#chennai - will have another cold night with a low of 20 deg C expected around morning. From Monday morning the low temp. will move above 21

"99B" - Still elongated North-South and with less convective activity.

"99B" - Still elongated North-South and with less convective activity.
8pm, Satellite IR shows less convective activity over North, West quadrant of the circulation. 
Signs of COLD Dry wind prevailing over N,W Bay is affecting the convective activity and further strengthening.
A weak circulation can also be seen over S-E corner of Arabian sea.


It's expected, around tomorrow evening the system will consolidate and move further West. Not expected to become as a Cyclone.  At the same time the cold dry winds from N-W India entering into N,W Bay will weaken or stop.

Due to the Dry winds present along N,W,W-central Bay the convective activity of the system will be concentrated over its N-E,S,E quadrant only till 2 /3-Dec.

Latest NOGAPS predicts LESS rainfall for central coast, Interior Tamilnadu from this system. 
But GFS model suggests good rain for central, N.Tamilnadu coast.. and it'll start from 3-Dec.


This weekend's outlook put up on blog...colder conditions expected.....system as a WML may move west...
http://rajesh26.blogspot.com

W.D over Kashmir has cleared off in a jiffy .. And NO W.D expected till 4 / 5-Dec.
If the Bay low survives and moves west .. showers expected to start along central,N.Tamilnadu coast from 3 / 4-Dec.. Till then COLD mornings
@dsanjeevkumar #chennai - records a low temp. of 19.5 deg C today morning.

"99B" - an elongated LOW pressure system now.

"99B" - is an elongated LOW pressure system now.
In next 2 days, it's expected to consolidate while moving west and may not develop into into a Cyclone.
Latest analysis by NOGAPS model suggests an elongated LOW extending from N-N-E to South along 90 E Longitude. But COLA analysis plots the circulation just North of 10th parallel.

AN AREA OF CONVECTION HAS PERSISTED NEAR 9.5N 90.9E,
APPROXIMATELY 670 NM EAST-NORTHEAST OF COLOMBO, SRI LANKA. RECENT
ANIMATED INFRARED SATELLITE IMAGERY SHOWS DEEP CONVECTION FLARING
OVER A DEVELOPING LOW LEVEL CIRCULATION CENTER (LLCC) EVIDENT IN A
292104Z  AMSU-B PASS. THIS DISTURBANCE LIES BENEATH AN UPPER LEVEL
RIDGE AXIS, WITH LOW VERTICAL WIND SHEAR AND FAVORABLE DIFFLUENCE
ALOFT. HOWEVER, THE LLCC IS EXPECTED TO MOVE WESTWARD INTO AN AREA OF
HIGHER VERTICAL WIND SHEAR AND WILL LIKELY ENTRAIN DRIER AIR PRESENT
ACROSS THE WESTERN BAY OF BENGAL IN THE DAYS AHEAD, LIMITING THE TIME
WINDOW FOR FURTHER DEVELOPMENT. MAXIMUM SUSTAINED SURFACE WINDS ARE
ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED
TO BE NEAR 1005 MB. BECAUSE THE LLCC IS JUST BEGINNING TO DEVELOP,
THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS LOW.

NOGAPS suggests a Depression over S-Central Bay on 3-Dec and will move towards N.Tamilnadu coast.

COLA model also suggests a Depression over S-Central Bay on 3-Dec and expects to move towards central Tamilnadu coast.

#chennai - 4pm, having a dry day with medium high cloud cover. No sunlight for most of the day today. Mild breeze from N-N-E. Temp. now 29 C

Monday, November 26, 2012


A Low is likely to form in the Eastern Bay, East of the Andaman Islands, by the 28th of November. Initially, on 29th, it will strengthen a bit, and move Westwards, and cover the Bay Islands.
I see some hindrance in the further westward track. As of today, the SST around the Islands is 30-31c. The SST progressively decreases as we move west. And, the SST, as we reach the Southern India coast is 28c and around 27c in the NE Indian coastline. That, would deter the further westwards track of the system beyond 93E. 
In fact, there is a 40% chance, that the system could even move Northwards along the Myanamar coast.
Let me stress, that is the synoptic situation today, and my track estimate is based on this scenario.

More in Vagaries...
Night temp for N,N-W,N-central India will be a bit higher from tomorrow due to the upcoming W.D .. It'll be normal again from 29/30-Nov.
Almost NO rain forecast for entire peninsula from 28-Nov ... http://ow.ly/i/1axTN

"03B" - kind of cyclone system in Nov-1992

The tropical disturbance ,that became TC09B was fwst identified on the 011800Z November
Significant Tropical Weather Ad~isory by JTWC as a broad area of convection in the Bay of Bengal.
As the tropical disturbance tracked north-northwestward, its convection increased in amount and organization.

JTWC issued a Tropical Cyclone Formation Alert at 0221002, and the first warning at
0300002. Intensification continued until the tropical cyclone stalled on 5 November. With increasing
wind sheer aloft over the cyclone, a weakening trend set in on 6 November which continued until
TC09B dissipated over water two days later. The final warning was issued by JTWC at 0718002.

Anti-cyclone over Maharastra will push strong winds into S.Andhra, N.Tamilnadu... this'll reduce the easterlies effect in these zones.

This is the Anti-cyclone and How it'll push winds into S.Andhra, N.Tamilnadu thereby pushing Easterlies to South.. http://ow.ly/i/19Kp9
