Tropical depression 05B to bring moderate and heavy rainfall to Chennai
December 15th, 2009 - 1:57 pm ICT by ANIWashington, December 15 (ANI): Reports indicate that tropical depression 05B is dissipating on the coast of Sri Lanka today and over the next couple of days, but not before bringing some moderate and heavy rain over the next couple of days to some areas in Sri Lanka and the southeast coast of India, from Chennai, southward.
The measurements regarding 05B were made by the Tropical Rainfall Measuring Mission (TRMM) satellite, which is a joint mission between NASA and the Japan Aerospace Exploration Agency (JAXA).
The TRMM satellite passed over 05B when it was newly formed in the Bay of Bengal on December 11, 2009.
TRMM’s Microwave Imager (TMI) and Precipitation Radar (PR) instruments were used in the rainfall analysis.
That data is used to create visual images at NASA’s Goddard Space Flight Center, located in Greenbelt, Maryland.
The TRMM data showed a large area of rainfall near the center of the storm with some areas of intense rainfall greater than 50 mm/hr.
Tropical cyclone 05B, which had been predicted to impact the southeastern coast of India, weakened to a tropical depression while moving over northeastern Sri Lanka.
05B was producing heavy rainfall over areas of the southwestern Bay Of Bengal and eastern Sri Lanka when the TRMM satellite passed over on December 14, 2009.
The rainfall analysis was derived from TRMM’s Microwave Imager (TMI) and Precipitation Radar (PR) instruments and was overlaid on a combination infrared and visible image from TRMM’s Visible and Infrared Scanner (VIRS).
Chennai and southeastern India will see scattered thunderstorms over the next several days as the system winds down.
The areas in the southeast will experience scattered thunderstorms with light winds.
Some downpours could be heavy at times.
The current forecast calls for thunderstorms to diminish over southeastern India by Thursday, December 17. (ANI)
