TRMM

For the second day in a row deadly tornadoes hit the the southern United States. Mississippi was the hardest hit with nine people killed by tornadoes that hit Tupelo. The TRMM satellite had two good views as extreme weather continued moving through the area on Monday April 28, 2014 at 11:00 PM CDT (April 29, 2014 at 0400 UTC) and early Tuesday April 29, 2014 at 00:38 AM CDT (0538 UTC). Rainfall derived from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) data is shown overlaid on GOES-EAST infrared satellite images captured on April 29, 2014 at 0402 UTC and 0532 UTC.

The TRMM satellite flew over the southern United States on April 28, 2014 at 0454 UTC (April 27, at 11:54 CDT) and April 28, 2014 at 0632 UTC (1:32 AM CDT). At both times severe weather pushing through the central and southern United States was observed by the satellite. Tornadoes associated with these areas of powerful thunderstorms killed at least 16 people with 14 deaths reported in Arkansas. Rainfall from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments is shown above overlaid on GOES-EAST infrared satellite images received at close to the same time. The locations of

Tropical cylone Jack had weakened to a tropical depression when the TRMM satellite passed above on April 22, 2014 at 1120 UTC capturing data used in the images above. The approximate location of JACK's center is shown as a red circle. Almost all rainfall near the the tropical cyclone's center had ceased but TRMM PR found that Jack was producing rain at a rate of over 130mm/hr (about 5.1 inches) in outer bands.

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

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

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

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

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

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

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.
