In studies aimed at identifying indicators to predict the risk for non-communicable
diseases in urban affluent population, mid-arm circumference and neck circumference,
apart from BMI, were found to be good indicators to predict the risk of hypertension.
2000 school children from low socio-economic class were studied for anthropometry
and blood pressure. High prevalence of high Systolic Blood Pressure in them indicated
1) low body weights but relatively high body fat percentage and 2) developmental
origin of adult diseases. Early-life under-nutrition and risks for adult diseases
have shown that subjects who experienced stunting in early life (0-4 years) but
had higher adult BMI showed higher risk for dislipidemia. To reduce the prevalence
of anaemia among young rural girls, recipes of green leafy vegetables were standardized
and demonstrated (Figure 10.1). This resulted in the reduction of prevalence of
anaemia from 75 to 47%.

- Amylolytic
methanogenic strains with optimum amylolytic activity at 10ºC and cellulolytic
strains with optimum cellulolytic activity at 20-25ºC were identified. Microbial
ecology and biodiversity conservation programme led to: 1) genotyping of 50 alkaliphilic
and haloalkaphilic bacteria isolated from Lonar lake, Buldana, Maharashtra, 2)
developing of enrichments of psychrophilic methanogens from sediments of lakes
in Leh and Ladakh, 3) identifying and isolating of two hydrogenotrophic and one
acetoclastic methanogen from Lonar Lake, 4) isolating of thermophilic actinomycetes
from Pashan Lake, Pune.
- In plant biodiversity studies, chemical and DNA
profiling was done for 'Chirayat', 'Kutki' and 'Shankhapushpi' complexes. A list
of 38 endemic taxa occurring in Ratnagiri district was compiled. Nutraceutical
studies on wild fruits of Ziziphus ('Ber') were found promising for prebiotic
properties. Germplasm of Jatropha spp., Caesalpinia crista and Calophyllum inophyllum
were collected from Western Maharashtra for evaluation. The oil content in Jatropha
spp. varied between 31.48- 45.54%. Based on leads from Ayurvedic literature, the
ethanol extract of Dalbergia lanceolaria bark was investigated for analgesic and
anti-inflammatory activity. Plant extracts of Artemessia, Caesalpinia, Blumea
and Wagatea spp. showed free radical scavenging activity and hepatoprotective
activity against ethanol induced liver damage in liver slice culture.
- In soybean improvement programme, mutant lines with high oleic acid content
(>40%) were identified for improvement of oil quality. In 15 frontline demonstrations
conducted on farmers' fields, improved practice recorded 31% higher seed yield
than farmers' practices. 300 quintal breeder seed production was undertaken. In
the wheat programme, recently released durum wheat variety MACS-3125 was the highest
yielding durum in the zone (Figure 10.4). Bread wheat variety MACS-6145 possessing
excellent grain quality and resistance was notified for rainfed cultivation in
North-Eastern Zone. In studies on identification of markers linked to gluten strength
in durum wheat, four protein markers, one STS marker for low molecular weight
glutenin and two microsatellite markers showed significant association with the
trait and explained 7- 34% variation in the trait value.

In fungal taxonomy, taxonomic accounts of 38 species of the lichen genus Graphis,
including 20 species new to science have been prepared. In order to explore the
possibility of PUFA production in submerged as well as solid-state fermentation,
Thamnostylum sp. and Conidiobolus coronatus were screened using modified medium
and in different incubation periods showed the presence of ALA. In-vitro sporulation
in a non-sporulating endophytic fungus was carried out and six endophytic fungi
were successfully identified.

| Figure 10.5: Pieces of trisected hydra were irradiated separately
at 500 J/M2 UV at 254 nm and regeneration was monitored over a period of 5 days.
UV irradiation was found to induce ectopic foot formation in the middle pieces.
Out of seven such cases, two showed duplicated feet at the usual location (a,b),
two showed `twin' feet at the usual location (c,d), while the remaining three
showed beginning of foot formation in the middle of the body column (e-g). Note
an unusually large area showing foot-specific staining in the middle of the body
column in addition to the normal foot in one case (g). The remaining 17 irradiated
middle pieces did not exhibit ectopic foot formation (h) |
- In developmental biology, the effects of UVC and UVB on growth and pattern
formation in hydra were studied. UV irradiation interfered with pattern formation
in regenerating hydra, possibly by changing positional values, and promoted budding
in intact hydra. This is the first report on induction of ectopic feet formation
by UV in regenerating hydra and opens up the possibility of using UV irradiation
as a tool to understand pattern formation in the enigmatic hydra (Figure 10.5).
The results indicate that functional interaction between cytoskeletal components
and cell surface architecture evolved early in evolution.
- The Palaeobiology
Group has established 1) a permineralized palm leaf Hyphaeneorachis nawargaoensis
gen. et sp. nov., 2) the taxon Cocosoidocarpon indicum gen. et sp. nov. for a
small sized coconut having 'three eyes', 3) a unique entire and matured soboliferous
acaulescent palm Appamahabalea uhlii gen. et sp. nov. Aggluntinated foraminifera
of Lower Cretaceous age were found with the lower Palaeolithic tools at Attirampakkam,
Tamil Nadu. Palynological analysis of subsurface sediments from Hadi mangrove
swamps, Sindhudurg, Maharashtra yielded information about the ecological shifts
during the Early Holocene- Late Holocene Period.

| Figure 10.6: Template used and the optical storage
pattern realized employing the dual-frequency photonic switch | Synthesis
of materials with novel properties Functionalized dimers based on a naturally
available cholesterol moiety were synthesized in which mono, di and trialkoxy
salicyladimine mesogenic segments were tethered to the cholesterol part with flexible
alkoxy chains of different lengths. This covalent linkage through its parity and
length plays a crucial role in determining the phase behaviour. Confined
geometry experiments The delicate balance for self-assembly in liquid crystalline
systems can be tipped when the material is confined in finite-size geometries.
Our x-ray structural measurements showed that the extent of layering, the range
of the layered phase, etc. can be tuned by the dimensions of the containing medium. The
Centre has been working on various topics of the basic and applied aspects of
liquid crystals. Apart from designing and synthesizing new molecules with novel
architectures exhibiting specifically targeted functionalities, the research work
is being focused on many frontier and thrust areas of soft condensed matter science.
A notable mention is that of photonics, in which light can be controlled by light
as a stimulus. The Centre is at the forefront of research in this nascent field
and has already demonstrated the importance of photo-driven isothermal phase transitions.
On the application side, the Centre is not only working on devices based on new
principles but also developing better driving technologies for the now ubiquitous
Liquid Crystal Display devices. Emphasis is being given to nondisplay based applications
also such as optical storage devices, anisotropic electric conductors, etc. Other
Initiatives CLCR has also entered into an MOU to provide technical advice
and characterization services to Bharat Electronics Ltd., a premier public sector

materials, metal-glass composites, metal complexes, organic photodetectors and
magnetic materials has been undertaken. Low temperature (~4K) magnetic susceptibility
measurement of Cd-doped CMRs material revealed cluster glass behavior. Glassy
dynamics of lanthanide oxides and magnetization studies of synthesized nanostructured
iron oxides were analyzed. Structural and optical properties of ZnO-based heterojunctions
were investigated. Tunability of molecular rectification in donor-acceptor assemblies
and the effect of various substitutes in organic photodetectors were studied.
Methodologies suitable for ab-initio structural studies of metal complexes and
organic compounds from laboratory Xray powder diffraction data were developed. Department
of Organic Chemistry Concise enantioselective synthesis of furano lignans
(-)-dihydrosesamin and (-)-acuminatin and furofuran lignans (-)-sesamin and (-)-methyl
piperitol was achieved by radical cyclization of epoxides. A divergent protocol
has been developed for entry into bacillariolide I and II, inhibitors of the enzyme
Phospholipase A2, towards designing non-steroidal anti-inflammatory drugs. Direct
condensation of coumarins with acetone and chloroform in presence of base has
furnished a novel variant of the Bargellini reaction affording an expeditious
aproach to o-carboxyvinyl-phenoxy isobutyric acids. The utility of this method
has been demonstrated. A green protocol for the stereoselective debromination
of *vicinaldibromides by [pmIm]BF4 under Microwave Irradiation was developed.
Free radical-promoted conjugate addition of activated bromo compounds was explored
using titanocene(III) chloride as the radical initiator. Influence of alkoxy and
acetoxy groups at the homoallylic position in facilitating RCM of 1, 6-dienes
has been established. This phenomenon has been exploited for the synthesis of
carbocyclic core of the nucleoside BCA. Department of
Theoretical Physics Generic Einstein-Maxwell-Kalb-Ramond actions have been
studied the area of high energy physics and cosmology and conditions derived under
which they give rise to static spherically symmetric black hole solutions. Also,
the large fine tunings of phase parameters of generic low energy supersymmetric
models has been reduced significantly by identifying a cancellation in the flow
of the bilinear Higgs coupling. In the area of condensed matter physics, a spin
spin Hall effect has been predicted. The importance of taking into account the
turbulent characteristics of the flow when accretion around a massive object is
considered has been established. The presence of overlapping transfer RNA genes
in archael methanogens has been reported. Other Initiatives

Indian Institute of Astrophysics,
Bangalore The Indian Institute of Astrophysics (IIA) is devoted
to the study of Astronomy, Astrophysics and allied topics. The headquarters were
established in Bangalore and new field stations were established at Kavalur and
Gauribidanur. During the last decade, the Institute has identified a superlative
site for astronomy in the trans-Himalayan region of Ladakh and established the
Indian Astronomical Observatory (IAO) at an altitude of 4500 m on Mt Saraswati,
Hanle. Initially the observatory is equipped with the 2-m Himalayan Chandra Telescope
(HCT) operated remotely from the Centre for Research & Education in Science
& Technology (CREST), the newly set up campus of IIA in Bangalore. During
the year 2005, a total of 10 research papers have appeared in leading international
journals, apart from papers presented at conference proceedings and results disseminated
through international circulars. During 2005, the telescope was equipped with
an autoguider to track objects precisely over long durations. The Institute has
also expanded its operations into Space Astronomy through the UltraViolet Imaging
Telescope (UVIT) and the Indo-Israeli TAUVEX payloads, and into the ground153
based gamma-ray astronomy collaboratively with the Tata Institute of Fundamental
Research (TIFR), Mumbai, and the Bhabha Atomic Research Centre (BARC), Mumbai. Research
in a broad range of topics continued during the current year in the areas of observational
astrophysics. Major Scientific Achievements and Highlights
The installation of two units of the HimAlayan Gamma Ray (HAGAR) telescope
array at IAO, Hanle was completed (Figure 10.7). HAGAR consists of seven such
units located at the centre and corners of a hexagon of 50 m sides, situated in
the Nilamkhul Plain (4300 m above msl) at the base of Mt Saraswati. Each unit
consists of 7 light collectors of 90-cm diameter fixed on a single mount. The
detection technique maps the cone of Cerenkov radiation resulting from the interaction
of the celestial gamma-rays with the earth's atmosphere. The designing of the
UVIT payload has progressed well and the Preliminary Design Review is scheduled
in February 2006. UVIT, consisting of two co-aligned 40-cm diameter ultraviolet
imaging telescopes, forms a part of the multi-wavelength astronomy ASTROSAT Mission
scheduled to be launched by ISRO in early 2007. IIA is also participating in the
Indo-Israeli ultraviolet imaging experiment (TAUVEX), which consists of three
co-aligned 20-cm diameter telescopes. TAUVEX hardware is built by El-Op, Israel,
whereas the software for data acquisition and reduction is developed by IIA. The
payload is scheduled to be launched by ISRO on GSAT-4 in the year 2006. 
Figure 10.7: One of the two units of the HimAlayan Gamma Ray (HAGAR) Telescope
array installed at the IAO, Hanle. The telescope will have a total of seven units,
one located at the centre and six at the corners of a hexagon of 50 m sides
Fabrication
of the eight-stage modulation scheme polarimeter for the Vainu Bappu Observatory
is in progress. Work on building a WARM (White light Active Region Monitor) telescope
for imaging of the Sun on high temporal basis is in progress. Designing of mechanical
layout of the coelostat and its electronic control drive is completed. Imaging
of the Sun on fast mode is expected to throw light on the pre-flare build up of
non-potential energy in an active region. Sun and the
Solar System The program for digitization of photographic data at Kodaikanal
Observatory has been in progress. Recent observations indicate that line intensities
in coronal holes are affected in the lower transition region and even in the chromosphere.
IIA used the daily Calcium K filtergrams from Kodaikanal to probe the signatures
of coronal holes in the chromosphere. Analysis of the data obtained from Brazil
during the solar eclipse of 3rd November, 1994 at 1.5 GHz, showed that a source
of angular size of 12 arcsec was associated with the active region AR 7798. Investigations
of the dust morphology of comet 2001Q4 have been completed. The VBO data clearly
shows the location of the dust plume that occured about 9 hours after the impact. Stars
and Stellar Systems An analysis of ultraviolet spectra of Extreme Helium
Stars has provided new clues to their origins. A new photometric method was derived
for measuring the distances to interstellar clouds that uses multi-band (B,V,R,I,J,H,K)
photometry of stars in the region of the clouds and an extinction law. This method
was used to determine distances to 9 interstellar clouds to an accuracy of about
15 - 20 %. Photometric observations to detect the halo of the LMC were obtained
using the 4.0m and 1.0m telescopes at CTIO, Chile in October 2005. Photometric
observations of 8 candidate old open clusters in our Galaxy were obtained using
the HCT in August 2005. Classical novae V1663 Aql, V476 Sct and V477 Sct, three
new novae in outburst discovered in 2005 were spectroscopically monitored using
the 2m HCT (Figure 10.8). In addition, an extragalactic nova, Nova M31 #14 was
also monitored spectroscopically. An Indo-Japanese collaboration for studies of
low redshift core collapse supernovae was established. The peculiar type Ib supernova
SN 2005bf was observed around maximum using the 2-m HCT. 
Figure 10.8: M 51, a spiral galaxy in which a supernova SN 2005cs erupted. This
image was obtained in the R band with the 2m HCT. The supernova which is a sub-luminous
Type IIp has been extensively followed by us both photo-metrically and spectroscopically
A
programme for coordinated, two-station monitoring of radio quiet quasars (RQQs)
has been going on with NCRA. Optical monitoring of these objects is being done
using the 2m HCT and the 1m ST of ARIES. Scientists have been working on radio
pulsars-theory and observations. From the observed pulsar profiles, methods for
estimating the rotation effects such as aberration-retardation on the phase shift
of pulse components have been developed. Non-accelerator
Particle Physics A variety of topics in non-accelerator particle physics
and atomic astrophysics were studied. Investigations were conducted on two important
probes of physics beyond the Standard Model- parity non-conservation (PNC) in
atoms and electric dipole moments (EDMs) of atoms. The work on PNC in Ba + has
reached an accuracy of less than one percent. Research was conducted on a new
approach to the high precision calculation of ground and excited state atomic
properties that are relevant in the study of fundamental symmetries and different
astrophysical processes. Theoretical Astrophysics The
analytical formulae derived for the scattering phase matrix have been studied
in the limiting cases of Zeeman and Hanle regimes in the two level case with angular
momentum 1 for the upper level and 0 for the lower level. Relativistic Fock-space
Coupled Cluster and multi-reference many body perturbation methods were developed
and applied to compute transition energies and related properties for closed shell
atoms. A scheme was also developed to compute P,T-odd interaction constant for
diatomic polar molecule containing heavy elements (YbF and BaF). Other
Initiatives A total of 73 research publications have appeared in research
journals, and 38 in conference proceedings. The observational and infrastructure
facilities at all the field stations were strengthened further. Special mention
may be made of the installation of a 30 kWp solar photovoltaic array at Hanle
to supply electric power to the HimAlayan Gamma Ray (HAGAR) telescope project
under development. An Indo-Chinese workshop on 'Recent Advances in Solar
Physics' was organized in November 2005. Considerable progress was achieved in
planning new solar initiatives at IAO, Hanle, and in the preparations for coordinated
activities during the International Heliophysical Year (IHY-2007). A Memorandum
of Understanding is in preparation for a larger project of Major Atmospheric Cerenkov
Experiment (MACE) coordinated by BARC in collaboration with TIFR and IIA. A twoday
mini-workshop was held in IIA, Bangalore in November to discuss the Gamma Ray
Astronomy and future prospects in the country. 21 young scientists are being
trained in the Institute towards their Ph.D. degrees; another four have submitted
their Ph.D. thesis during the current year. The members of the Institute continued
their teaching activities in the Institute, Joint Astronomy Program at the Indian
Institute of Science, Bangalore University and other centres. Several scientists
offered advanced level courses to students in universities and trained them in
Astronomy and Astrophysics. The Human Resource Development is also continuing
through the research and engineer trainee programmes, summer project students
programme, degree project programme, visiting Ph.D. students programme, etc. Indian Institute Of Geomagnetism,
New Panvel, Mumbai The main areas of research at the Indian Institute
of Geomagnetism (IIG) are: Observatories and Data Analysis, Upper Atmospheric
Sciences, and Solid Earth Geomagnetism. The instrumentation division of IIG is
involved in development and maintenance of various instruments used for observations
in the above areas. Major Scientific Achievements and
Highlights Observatories and Data Analysis The
Institute continued to operate nine magnetic observatories at different locations
in the country, where magnetic field variations were continuously recorded. An
Induction Coil Magnetometer was deployed at IIG's Laboraory at Allahabad. Ranges
and amplitudes computed for magnetic storms were classified with reference to
their occurrence features at Indian stations, and forwarded to World Data Centre
(WDC), Colorado, for inclusion in the Geophysical Data Bulletin. The final definitive
data for Alibag up to December 2004 were forwarded to the Danish Meteorological
Institute, for inclusion in the Annual CD-ROM brought out by them. Eighteen magnetic
compasses of Landing and Datum type, received from Indian Navy, were calibrated
at magnetic observatory Alibag. A comparative study of secular variation
of the main geomagnetic field, at Alibag (10o N dipole latitude) and Indian Antarctic
station, Maitri (67o S dipole latitude) showed that at Alibag no significant 156
DST ANNUAL REPORT 2005-2006 decrease was seen in the last century, whereas at
Maitri the magnetic field decreased by about 2500 nT in the last two decades (Figure
10.9).

locations are also shown. redistribution of water vapour that compete with the
dominant migrating tide to induce the observed inter-annual variability in the
diurnal tide found during the El Nino-La Nina years of 1997-1999.
Upper
Atmospheric Sciences A two-dimensional electrostatic particle code using
curvilinear coordinates is being developed to study the auroral electron acceleration
mechanism. Simultaneous observations of equatorial spread F (ESF) irregularities
made using 18 MHz HF radar at Trivandrum and two spaced receivers at Tirunelveli
that recorded ionospheric scintillations on a 244 MHz radio wave signal transmitted
from a geostationary satellite, were used to understand the evolution of spatial
structure in ESF irregularities in the post-sunset equatorial ionosphere. Analysis
of night airglow data of OH (8,3), OH(6,2) and OH(7,2) bands, from Kolhapur, was
continued to infer the temperature of the mesosphere and validate atmospheric
models. An airglow photometer to monitor F-region atomic oxygen emission at 630.0
nm was made operational at the Equatorial Geophysical Research Laboratory (EGRL)
of IIG at Tirunelveli. Analysis and interpretation of existing datasets from 2001-2004
of atmospheric air-earth current measurement at the Indian Antarctic Station,
Maitri, was carried out for understanding some features of the global electric
circuit. Instruments and techniques were developed to measure the atmospheric
conduction current. Long-term MLT radar observations of the diurnal tide
at 86 km over Tirunelveli during the years 1993-2004 exhibited a pronounced annual
cycle that was modulated on inter-annual time scales. Removal of composite seasonal
cycle yielded 'anomalies' in the diurnal tide over Tirunelveli that were compared
with the quasibiennial oscillation (QBO) wind at 30 hPa derived using the Singapore
radiosonde data and satellite derived Outgoing Longwave Radiation (OLR) anomalies
over this region (Figure 10.10). Lower atmospheric large-scale convective systems
originating in the southern tropical latitudes over the western Pacific region
in response to the El Nino Southern Oscillation (ENSO) possibly facilitate excitation
of non-migrating tides through latent heat release or large-scale

Solid Earth Geomagnetism In magneto-telluric
(MT) surveys conducted in the Andaman region; a major NNE-SSW trending thrust
zone, with eastward dip of about 60 degrees, was delineated. MT studies in the
Lower Assam valley and Shillong Plateau identified thrust zones corresponding
to Oldham and Dauki faults. Analysis of MT data collected in the Kaladgi basin,
shows a strike direction of N45°W which is close to the major geological strike
direction of the study area. Preliminary results of the Geomagnetic depth sounding
data over Andaman suggest presence of conductivity structure between Car Nicobar
Islands and Little Andamans. Curie isotherm depths were estimated from aeromagnetic
anomaly map over certain regions in India (Figure 10.11). The mobile belts had
shallower Curie isotherm when compared to the cratons. The depth estimates matched
those calculated from the MF4 lithospheric model of Champ satellite.

in the Central Indian region. Brown represents magnetic sources associated mainly
with iron ores, trap flows, charnockites. Various fault, shear, and thrust zones
are also indicated
Third repeat geomagnetic survey conducted in Jabalpur-Kosamghat
area observed higher annual changes in the total magnetic fields along the identified
Satpura conductor could be due to fluids trapped in the crust. The environmental
magnetism group carried out field surveys of Mumbai and Navi Mumbai for studying
pollution characteristics using magnetic measurements. Analysis of Loess samples
of central higher Himalaya has yielded a monsoon climate record for the past 20Ka
(Figure 10.12).

record over Indian subcontinent: Climate sensitive mineral magnetic ratio called
S-ratio reflects accurately the palaeoclimatic changes over the entire Indian
subcontinent. High magnetic ratios corresponding to high 'magnetite to haematite'
ratios are found in the wet spell sediments and vice versa. The S-ratio record
of the Himalayan Dhakuri loess clearly outlines key climatic events over the past
20 ka revealing step-wise improvement in SW monsoon since Last Glacial Maximum
(LGM), culminating in its establishment around 9 ka. | Palaeomagnetic
investigations were carried out on the dyke samples of Bundelkhand craton, Nasik
and Kutch. Initial phase of Deccan magmatism was identified in these studies.
IIG's first global positioning system (GPS) campaign in Andaman and Nicobar Islands
was carried out. GPS field campaigns were also undertaken in Garhwal and Kumaon
regions of Middle Himalayas to study crustal motion in these regions. Other
Initiatives Instrumentation Division Coil designs
for a declination-inclination (dI-dD) magnetometer were finalized and submitted
to CDM BARC for fabrication. Two PPMs with 1 nT sensitivity were assembled for
making observations in Antarctica. Two single board based data-loggers and one
Fluxgate Magnetometer were also assembled. Antarctica
Expedition One IIG staff member, who participated in the XXIV Indian Antarctic
Expedition, is in Antarctica through the winter period, to carry out IIG's experiments
related to monitoring of magnetic field variations by DFM, decrease in total magnetic
field by a PPM, atmospheric absorption by riometer, and airearth current measurements.
Experiments related to crustal deformation and glacier movement using Global Positioning
System (GPS) were carried out during the Antarctic summer. Two members from the
Institute were selected for the XXV Indian Antarctic Expedition. Capacity
Building One student was awarded a Ph. D. degree. Five students are working
towards their Ph.D. degrees. Two M.Sc. (Space Physics) students from Department
of Physics, Andhra University, Visakhapatnam, completed their project work on
"Airglow studies" in IIG in May and June 2005. Two students from Paramakaliany
College, Tenkasi, Tamil Nadu, are doing their M.Sc. project work at EGRL, Tirunelveli.
IIG scientists continued to conduct courses in the area of Space Physics, for
M.Sc. students of the University of Mumbai. Website First
phase of the WDC - Mumbai website was launched to facilitate access to hourly
data from the Indian magnetic observatories. Old magnetograms for the period 1901
to 1920 were converted into digital image files using a high-resolution digital
camera, as part of an IAGA project for retrieval of old magnetograms, and sent
to WDC, Kyoto. Public Outreach IIG along with seventeen
other major scientific institutions of the country participated in a five-day
Science Exposition, held at Nehru Science Centre, Mumbai, during 22-27 November
2005. Two popular science talks on "Current Global Warming: Can Schumann
resonance amplitudes provide the current temperature scale?" and "Some
nuggets of Geomagnetism and Paleomagnetism" were delivered by IIG scientists
during this exhibition. Publications and participation
in conferences Published 23 papers in reputed national and international
journals. Five papers, including 2 invited talks, were presented at the 11th International
Symposium on Equatorial Aeronomy, held in Taiwan in May, 2005. Twenty four papers,
including 2 invited talks were presented at the 10th Scientific Assembly of the
International Association of Geomagnetism and Aeronomy (IAGA) held at Toulouse,
France during July, 2005. At this conference, IIG scientists convened 2 sessions
and chaired 3 sessions. Ten papers, including 2 invited talks were presented at
the XXVIII Genral Assembly of the International Union of Radio Science (URSI)
held in New Delhi in October, 2005. Honours/Awards A
scientist was given a "Young scientist award" for 2005 by URSI during
its General Assembly in New Delhi. Long Service Award was given to a Senior Technical
Officer by IAGA for his dedicated services. Indian Institute of Tropical Meteorology,
Pune The Indian Institute of Tropical Meteorology functions as a
National Centre for basic and applied research in Tropical Meteorology. Its primary
functions are to promote, guide and conduct research in the field of Meteorology
and Atmospheric Sciences in all its aspects with special reference to the tropics
and sub-tropics. Major Scientific Achievements and Highlights The
highlights of the progress made in the on-going programmes during the year are
summarized below: Extended Range Weather Prediction Research For
seasonal prediction of Indian summer monsoon rainfall, a Neural Network Model
was developed using De-Bilt January temperature anomaly, sea ice extent anomaly
in Antarctic in winter, Northern Atlantic Oscillation (NAO) in the month of April
and tendency of Effective Strength Index (ESI), from January to April. The model
was tested for the period 2001 - 2004. The model well predicted the large deficient
years 2002 and 2004. The Heidk Skill score for the model was found to be 0.7.
By using the Neural Network Model, seasonal forecast for 2005 was prepared and
was found to be + 4%. Simulations of monsoon 2005 from both the Centre for Ocean
Land Atmospheric Studies (COLA) and Portable Unified Modes (PUM) models indicated
below normal seasonal monsoon rainfall over the Indian region. Seasonal
Prediction of Indian Summer Monsoon Experimental forecast of the seasonal
total (June - September 2005) of the Indian Summer Monsoon Rainfall (ISMR) for
the country as a whole was attempted, by using predictors selected only from sea
surface temperature (SST) field, Empirical forecast from this method can be obtained
three months in advance. The forecast obtained for the year 2005 ISMR was found
to be 12% below normal. Studies of Monsoons and Tropical
Weather System A simple regression equation was developed to predict the
date of onset of Indian summer monsoon over Kerala. The equation was used to predict
the date of onset over Kerala for monsoon 2005, by using the information of daily
thunderstorm activity over south peninsular India during April 2005. The equation
suggested 5 June as onset date for the year 2005 which was later observed to be
the same. Dendroclimatic Analysis over Western Himalaya Ring
width data of Cedrus deodara D. Don [Himalayan Cedar], collected from five locations
near Gangotri, Uttaranchal Himalaya were analyzed. Noticeable feature of all the
series was found to be unprecedented surge in tree growth after around A.D 1930.
Such anomalous behavior was not observed prior to A. D. 1930 which may be possible
due to the effect of enhanced winter warmth. Analysis of surface air temperature
over Western Himalaya indicated significant increasing trend in maximum and mean
temperature during 20th century. More warming during recent four decades was also
noticed in minimum temperatures in the region. Hydrometeorological
Studies of River Basins Under the project entitled Preparation of generalized
PMP Atlases over the Krishna and Indus river basins, based on a long period daily
rainfall data of 570 stations in and around the Krishna river basin 8 to 10 severe
rainstorms over each of 5 sub-catchments of the basin were analysed by Depth-
Duration (DD) or Depth-Area-Duration (DAD) depending upon orography of the region. Heliospheric
Current and Indian Summer Monsoon Actual rainfall data were bifurcated into
two groups (i) Rainfall falling under (-, +) crossing events and (ii) Rainfall
falling under (+,-) crossing events. Indian summer monsoon rainfall in all the
states was found to have an in phase relation with (-, +) crossing events. i.e.
magnetic sector boundary polarity towards the sun (heliospheric current) followed
by more summer monsoon rainfall activity. Cyclonic Storms
/ Depressions and Magnetic Sector Boundary Events A study was carried out
to examine the relationship between number of cyclonic storms and depressions
forming over tropical seas and Magnetic Sector Boundary (MSB) Crossing Events.
Studies revealed that number of cyclonic storms and depressions were found to
have in-phase relation in June and September and out-of-phase relation in October
and December with (-,+) and (+,-) MSB crossing events, respectively. Impact
of Tsunami on Surface Ozone The unusual changes were observed in ozone and
NOx concentrations after the giant tsunami waves struck at Tranquebar, a tropical
rural coastal site on the east coast (the Bay of Bengal) of southeast India on
26 December 2004. The average maximum of O3 concentration was found to be unusually
reduced by 45% at noon and minimum of O3 concentration increased by 164% in the
morning due to tsunami impact. The unusual diurnal variation of O3 was observed
up to 19 January 2005 after tsunami impact due to changes in the photochemical
production and destruction of O3. Similarly average daytime and nighttime NOx
also increased from 5.6 ± 0.35 to 9.5 ± 0.66 ppbv and 6.5 ±
0.22 to 9.2 ± 0.34 ppbv with 1 ó standard deviation due to tsunami
impact. Whistler Studies during Magnetospheric Disturbances Whistler
triggered emission at a low latitude station during moderate magnetic storm activity
was explained using the Doppler-shifted cyclotron resonance interaction between
whistler mode wave and counter streaming energetic electrons. The estimated wave
magnetic field, transverse resonant current and interaction length were found
to increase during disturbed magnetospheric conditions while the number of energetic
electrons participating in resonance processes under normal and disturbed conditions
remains approximately the same. Analysis of ARMEX Data Measurement
of ion concentration and electric conductivity during the ARMEX showed that the
value of polar conductivity was much higher during the monsoon than the pre-monsoon
season. Other Initiatives Organisation

External Cash Flow
The performance of ARCI
in terms of External Cash Flow (ECF) and other parameters has been creditable
during the year 2004-2005. In fact, if the performance of ARCI in the last 5 years
(from 2000-2001 to 2004-2005) is considered, the total ECF has been around Rs.60
crores. Further, the ECF has averaged Rs.33 lakhs per scientist per year while
the cumulative ECF has exceeded the salary and welfare cost of all our employees
over a 5-year period by a factor of 4.3. Jawaharlal Nehru Centre For Advanced
