ISRO has already identified and selected sites in cosultation with Agricultural universities of southern states and installed AWS. Agrometeorological units of state Agricultural Universities disseminate daily [local] forcast in collabaration with IMD. [Ref:www.imd.gov.in]But ISRO installing Dopplar Weather Radar [DWR] is a new information; That too at Cherapunji the world's wettest place. If it is true ISRO must consider installing DWR at Kanyakumari, Chinna Kallar,and other meteorological vantage locations in the west.
Note that there is NO DWR in the west coast.
However, by instaling DWR at high mountain ranges, there is every possibilities that the signals will be reflected by mountain range. But I do not know the principles of DWR. I believe that installing DWR at KANYAKUMARI will definetely help understand the South West monsoon and the study of winds and other weather pattern in Indian Ocean.

"96B" - Update

The stationery movement of clouds may perphaps be due to the presence of HIGH pressure ridge hovering over NW & adjoining central India at 850 hPa level. Further the 300 hPa & above level winds are strong SWly and trying to drag it away from East Coast.



Today [10.12.2009/0300 UTC] surface charts depicts two or thre isobars closer by, thus indicating more Pressure Gradient Force (PGF)acros isobars. Obviously surface wind force will be stronger in the coast and (land too) and tides will be higher than normal during this period.

THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 6.2N 84.2E,
IS NOW LOCATED NEAR 6.5N 84.1E, APPROXIMATELY 254 NM EAST OF
COLOMBO, SRI LANKA. ANIMATED VISIBLE SATELLITE IMAGERY SHOWS 2
DISTINCT COMMA-SHAPED AREAS OF SUSTAINED AND DEEPENING CONVECTION
BEGINNING TO WRAP INTO AND ORGANIZE AROUND A CONSOLIDATING LOW LEVEL
CIRCULATION CENTER (LLCC). A 100425Z ASCAT PASS SHOWS WEAK WINDS AT
THE CORE OF A DISTINCT CIRCULATION CENTER WITH STRONGER (15 TO 25
KNOT) FLOW LOCATED APPROXIMATELY ONE DEGREE TO THE NORTH AND SOUTH
OF THE LLCC. COLOMBO (VCBI) IS CURRENTLY REPORTING SEA LEVEL
PRESSURE AT 1006 MB, WHICH REPRESENTS A 1 MB DECREASE FROM 24 HOURS
AGO. SUSTAINED WINDS ARE OUT OF THE NORTH-NORTHWEST AT 08 KNOTS. THE
UPPER LEVEL ENVIRONMENT IS CONDUCIVE FOR FURTHER DEVELOPMENT WITH
LOW VERTICAL WIND SHEAR AND STRONG RADIAL, AND ENHANCED POLEWARD,
OUTFLOW. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1004 MB.
THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS UPGRADED TO FAIR

NCMRWF - predicts very heavy showers for North Tamilnadu and South Andhra coast from 12-Dec to 15-Dec.

India to deploy more Doppler radars for weather forecast .. http://is.gd/5hOhX
Here's "96B" rain rate near Srilanka coast .. http://ping.fm/TAuUv
"96B" cloud mass is getting huge, now covering 90% of south Bay .. http://yfrog.com/auencj
Chennai - Mild day till now 3:03pm, with minor cloud formation and stiff wind from north-east. Cloud movement direction is also from North-E
NCMRWF predicts that the present "96B" will lay centered over north TN coast on 13-Dec.. http://ping.fm/6yvQK
Latest satellite shows "96B" has started affecting North-east Srilanka.. And it has slightly moved to west.. http://yfrog.com/1y5u3j
Almost every GFS predicts heavy showers for North TN and south Andhra coast from 12-Dec to 14-Dec .. http://yfrog.com/35k96j
METEOSAT-5 shot 10-Dec, 5:30AM IST.. shows big mass of Heavy cloud formation over "96B".. http://yfrog.com/4fmosg
METEOSAT-7 shot 10-Dec, 5:30AM IST.. shows big mass of Heavy cloud formation over "96B".. http://yfrog.com/4fmosg
Still GFS models predict heavy widespread showers for Central, north TN coast and into South Andhra coast.. till 14-dec-09
"96B" .. will move north-west from 11-Dec and will die near south-Andhra coast on 13-Dec.. http://ping.fm/pCmnE
How many more days this NON moving "96B" over Bay will last? .. All GFS models suggest that "96B" will MOVE west towards Land on 12-Dec-09.
"96B" in fact has moved slightly SOUTH.
Latest satellite shot of "96B" .. slightly disorganized and NO sign of movement towards land or into Bay .. http://ping.fm/Q2GGg
Chennai - A clear morning with slightly low temperature than yesterday morning .. 23.4°C (5:47am)
