Tropical Disturbance Adds Rain To Philippines

On April 21, 2014 at 2219 UTC the TRMM flew over stormy weather within a tropical disturbance near the Philippines. Precipitation from this tropical low adds to above normal rainfall for the Philippines during the past 30 days. Heavy rainfall with the slow moving remnants of tropical depression Peipah caused flooding in the Philippines earlier this month. TRMM's Precipitation Radar data were used to make a 3-D vertical slice through the tallest thunderstorm towers in this area of stormy weather. This slice shows that some storms were returning radar reflectivity values of greater than 52dBZ

Tropical Cyclone Ita Drenches Australia

After coming ashore this past Friday tropical cyclone ITA dropped heavy rainfall over the weekend that caused flooding in many areas of northeastern Australia's state of Queensland. IDA has now moved back into the Coral Sea. The analysis above shows a TRMM-based near-real time Multi-satellite Precipitation Analysis (TMPA) made at the NASA Goddard Space Flight Center. This analysis used TMPA precipitation data from April 1-14, 2014 during the period when ITA formed in the Coral Sea and moved along northeastern Australia's coast. IDA's locations at 0600 UTC are shown overlaid in white. The

Powerful Tropical Cyclone Ita Hits Australia

As predicted, powerful tropical cyclone ITA hit the Queensland coast of northeastern Australia late Friday (local time). At that point ITA was a category four on the Saffir-Simpson hurricane intensity scale with winds estimated at over 120 kts (about 138 mph) . This intensity was down slightly from ITA's estimated peak sustained wind speed of 135kts (about 155 mph) when the dangerous tropical cyclone was approaching Australia. The TRMM satellite passed almost directly above as tropical cyclone ITA was approaching the Queensland coast on April 11, 2014 at 0523 UTC. At the time of this TRMM view

TRMM Sees Powerful Tropical Cyclone Ita Approaching Queensland, Australia

Tropical cyclone ITA, located in the Coral Sea northeast of Australia, continues to intensify while heading toward the northeastern coast of Australia. ITA was seen twice by the TRMM satellite on April 9, 2014. The tropical cyclone's wind speeds had increased from 65kts (about 75 mph) with the first pass at 0536 UTC to 80kts (about 92 mph) when viewed again at 1528 UTC. ITA is predicted to continue becoming more powerful and have sustained winds of 135 kts (about 188 mph) before hitting Australia's Queensland coast tomorrow. TRMM's Precipitation Radar (PR) instrument sliced through ITA's eye

Tropical Cyclone Ita Intensifies

The TRMM satellite flew above intensifying tropical cyclone ITA in the Coral Sea near the southeastern tip of Papua New Guinea on April 9, 2014 at 0536 UTC. The tropical cyclone had developed a large but well defined eye and had sustained winds estimated at 65kts (about 75mph). Rainfall derived from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) data was used in the analysis shown here. TRMM PR data unveiled rain falling at a rate of over 99mm/hr (about 3.9 inches) within ITA's feeder bands over the coast of southeastern Papua New Guinea. TRMM PR found that tall thunderstorms in

TRMM Sees Severe Weather

The TRMM satellite flew over the southeastern United States on April 7, 2014 at 1300 UTC (9:00 AM EDT) when a line of intense thunderstorms was moving through the area. Tornado watches were in effect over much of the area. A possible tornado, associated with the same weather system, caused destruction and injuries when it moved through southern Mississippi earlier at about 2 AM EDT. TRMM's Precipitation Radar (PR) data revealed that rain was falling at a rate of over 130mm/hr (about 5.1 inches) in one severe thunderstorm near the Alabama and Florida panhandle border. A radar reflectivity value

Tropical Cyclone Hellen's Lively Remnants

Powerful tropical cyclone Hellen rapidly weakened after hitting northwestern Madagascar but Hellen's remnants have recently started to show signs of life. The TRMM satellite flew over these remnants in the Mozambique channel on April 2, 2014 at 0143 UTC. A rainfall analysis using TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments found that some strong convective thunderstorms had developed in the area. It was revealed by TRMM PR data that rain was falling at a rate of over 75 mm/hr (almost 3 inches) in a few locations.

Tropical Cyclone Hellen

Tropical cyclone HELLEN formed in the Mozambique channel northwest of Madagascar on March 28, 2014. HELLEN became a very powerful tropical cyclone with peak sustained winds of 130kts (about 150 mph) on March 30, 2014. HELEN's eye came ashore in northwestern Madagascar On March 31, 2014 with winds predicted to be about 95kts (~109 mph). HELEN is now expected to gradually weaken over northwestern Madagascar while moving southwestward and be over the Mozambique Channel again on April 1, 2014. The TRMM satellite passed above HELLEN on March 30, 2014 at 1747UTC when the tropical cyclone was close

Gillian Has Second Life

Tropical cyclone Gillian re-generated in the South Indian Ocean south of Indonesia on March 21, 2014. Gillian had peak wind speeds of about 140 kts (about 173 mph) on March 23, 2014 making it a Category 5 hurricane on the Saffir-Simpson Scale. The TRMM satellite flew above GILLIAN when the tropical cyclone was intensifying on March 23, 2014 at 0304 UTC. Data from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments were used in the rainfall analysis on the above left. TRMM PR revealed that Gillian had very intense storms in a well defined eye wall producing rain at a rate of

Gillian's Persistent Remnants

The persistent remnants of tropical cyclone GILLIAN have moved westward over 2700km (about 1674 miles) since forming in the Gulf Of Carpentaria on March 8, 2014. GILLIAN's coherent remnants were located just to the southeast of the Indonesian island of Java when the TRMM satellite flew over on March 20, 2014 at 0415 UTC. TRMM's Precipitation Radar (PR) instrument revealed that intense convective storms in this area were still dropping rain at a rate of over 97 mm/hr (about 3.8 inches) and returning radar reflectivity values of over 51dBZ. TRMM PR data were used in the simulated 3-D view on the
