Likely Tropical Cyclone near Philippines

Sunday, April 3, 2011

The TRMM satellite flew over an area of disturbed weather east of the Philippines on 3 April 2011 at 0129 UTC collecting data used in the image above. This area contains very intense thunderstorms with tops shooting to heights above 17 km (~10.6 miles). Heavy rainfall in these thunderstorm towers can provide the energy needed for tropical cyclone (typhoon) development.

Tropical Cyclone Bune

Friday, March 25, 2011

Tropical cyclone BUNE was southeast of the Fiji Islands and close to a category one on the Saffir-Simpson scale when the TRMM satellite passed above on 24 March 2011 at 1548 UTC. TRMM Microwave Imager (TMI) and Precipitation Radar (PR) data from this pass show that large rain bands around BUNE contained numerous intense thunderstorms. BUNE is expected to peak as a category two tropical cyclone with wind speeds of about 85 kts (~98 mph) on 26 March 2011 while moving over the open waters northeast of New Zealand.

TRMM’s TMI and PR instruments observed Cyclone Yasi as it developed from a Category 3 tropical cyclone (Feb. 1st, left), to a Category 5 event (Feb. 2nd) when it made landfall with wind gusts reported at up to 186 mph, and then finally as it began to dissipate on Feb. 3rd (right).

Stormfront approaching the city of Bangalore, India Source: Manish Bansal Constantly scanning the Earth’s surface, the GPM Microwave Imager (GMI) allows scientists to both track tropical cyclones and forecast their progression. Used by NOAA’s National Hurricane Center (NHC), the Joint Typhoon Warning Center (JTWC), and tropical cyclone centers in Japan, India, Australia and other countries, detailed microwave information provides data on the location, pattern and intensity of rainfall. Tropical Cyclone Eunice in the South Indian Ocean on January 28, 2015. GPM's Microwave Imager (GMI) found...
