Amanda Weakening

Amanda Weakening
Once powerful hurricane Amanda was weakening to tropical depression intensity when the TRMM satellite passed above on May 29, 2014 at 1038 UTC. A rainfall analysis derived from TRMM data is shown overlaid on a GOES-15 enhanced infrared image. TRMM's Microwave Imager (TMI) found rain falling at a rate of slightly over 47 mm/hr (about 1.9 inches) in storms located between Amanda's center and Mexico's coast. Amanda's locations and intensities are shown in red.

Eastern Pacific Category Four Hurricane Amanda

Eastern Pacific Category Four Hurricane Amanda
The first hurricane of the eastern Pacific hurricane 2014 season, called Amanda, reached wind speeds estimated at 135 kts (about 190 mph) on May 25, 2014. This made it a category four on the Saffir-Simpson hurricane wind scale. Fortunately the powerful hurricane was over open waters well to the southwest of Mexico's coast when the maximum intensity was reached. The images above show data collected when the TRMM satellite passed overhead on Saturday May 24, 2014 at 2150 UTC. Rainfall data from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments are shown overlaid on a GOES-15

Lecture: Finding Hot Towers in Hurricanes

Owen Kelley, research scientist at NASA Goddard Space Flight Center,  discusses the science, the technology and the researcher who coined the term "hot tower" 50 years ago. During the past decade, NASA's Tropical Rainfall Measuring Mission satellite has been able to collect definitive statistics on the association of hot towers (towering thunderclouds) and hurricane intensification.

Hurricane Raymond's Copious Rainfall Analyzed

Hurricane Raymond's Copious Rainfall Analyzed
Powerful hurricane Raymond, located off Mexico's south-central Pacific coast, has weakened to a tropical storm. It has now started to move slowly away from the location where it has been parked since Monday October 21, 2013. Raymond dropped abundant rainfall in much of the same area already hit by deadly flooding and landslides with Hurricane Manuel last month. The rainfall analysis above was made at Goddard Space Flight Center using TRMM-based, near-real time Multi-satellite Precipitation data (TMPA) collected during the period from October 15 to 23, 2013. Rainfall totals greater than 125mm (

Hurricane Raymond Soaking Mexican Coast

A month ago hurricane Manuel caused caused landslides and extensive flooding along Mexico's Pacific Ocean coast. Recently formed hurricane Raymond is expected to cause heavy rainfall in nearly the same area. The TRMM satellite flew directly above hurricane Raymond on October 21, 2013 at 0111 UTC (October 20 at 6:11 PM PDT). TRMM Precipitation Radar (PR) data from that orbit shows that hurricane Raymond contained towering thunderstorms on the western side of the eye wall that were reaching to heights above 15km (~9.3 miles). TRMM PR also recorded precipitation in Raymonds eye wall that was

Deadly Manuel Becomes A Hurricane

Deadly Manuel Becomes A Hurricane
As predicted by the National Hurricane Center (NHC), tropical storm Manuel became a category one hurricane yesterday evening. Manuel, located over the southern Gulf Of California, was an intensifying tropical storm with maximum wind speeds of about 50kts (~57.5 mph) when viewed by the TRMM satellite on September 18, 2013 at 1845 UTC. Manuel had intensified and was a minimal hurricane, hugging Mexico's coast, with wind speeds of about 65kts (~75.8 mph) when seen again by TRMM on September 19, 2013 at 0116 UTC. Rainfall analyses that used TRMM's Microwave Imager (TMI) and Precipitation Radar (PR

Heavy Rainfall on Mexico's Pacific and Gulf Coasts

Mexico's Pacific and Gulf coasts are both being inundated by tropical cyclone rainfall at the same time. Tropical storm Manuel has dropped very heavy rainfall along Mexico's Pacific coast. 21 people have been reported killed in this area due to flooding and landslides caused by extreme rainfall. At the same time hurricane Ingrid weakened to a tropical storm and came ashore from the Gulf Of Mexico into the state of Tamaulipas near La Pesca, Mexico . The approximate 0000Z and 1200Z locations of the tropical cyclones are shown overlaid in white. The TRMM-based, near-real time Multi- satellite

Hurricane Ingrid Heads For Mexico

The TRMM satellite flew over on September 16, 2013 at 0227 UTC (10:57 PM September 16) when Ingrid was still a hurricane in the Gulf Of Mexico. Data collected by TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments show that rain was falling at a rate of over 100mm/hr (~4 inches) in strong storms near Ingrid's center.

Weaker Hurricane Humberto

Weaker Hurricane Humberto
Southwesterly wind shear has taken it's toll on hurricane Humberto. An eye was no longer distinct in data collected when the TRMM satellite passed over on September 12, 2013 at 1625 UTC (12:25 PM EDT). An analysis derived from TRMM Microwave Imager (TMI) and Precipitation Radar (PR) data shows that most of the precipitation with Humberto was then located in the northwestern quadrant. TRMM found that the most intense rain was falling at a rate of over 99mm/hr (~3.9 inches) at 22.4 North 28.7 West near Humberto's center. TRMM PR also found that the highest storm towers were reaching heights of
