TRMM

On November 1, 2013 at 1320 UTC the TRMM satellite had the second look at typhoon KROSA. KROSA weakened slightly when it passed over the northern Philippines but had started to intensify with this second pass over the South China Sea. The image on the left shows rainfall data collected by TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments overlaid on an enhanced infrared image. TRMM PR data revealed that rain was falling at a rate of over 116mm/hr (4.5 inches) in KROSA's eye wall. Radar reflectivity values greater than 50dBZ were found in the same area. The 3-D perspective

There has been some recent convective activity within tropical storm Raymond but southwesterly wind shear and cooler ocean temperatures are predicted by the National Hurricane Center (NHC) to weaken the tropical storm to a remnant low on Wednesday October 30, 2013. Raymond contained rainfall only in an area northwest of it's center of circulation when the TRMM satellite passed above on October 28, 2013 at 2337 UTC (4:37 PM PDT). Rainfall data from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) are shown overlaid on a combination visible and infrared image from TRMM's Visible and

Tropical Storm Lekima Tropical Storm Francisco The TRMM satellite flew above the centers of two tropical cyclones in the western Pacific Ocean early this morning. The first orbit saw super typhoon LEKIMA at 0745 UTC and with the next orbit tropical storm FRANCISCO came into view at 0919 UTC. Lekima was located southeast of tropical storm Francisco over the open waters of the Pacific. Precipitation data from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instuments are shown overlaid on infrared images from TRMM's Visible and InfraRed Scanner (VIRS). These rainfall analyses show the

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 (

Typhoon Francisco was headed toward the islands of southern Japan when the TRMM satellite had a good view on October 22, 2013 at 0933 UTC. Francisco was weakening and had estimated winds of less than 75kts (~86 mph) with this TRMM pass. An analysis derived from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments is shown overlaid on an enhanced infrared image from TRMM's Visible and InfraRed Scanner (VIRS). This analysis showed that the most intense rain was falling at a rate of over 75mm/hr (~3 inches) in a location well to the southwest of Francisco's center of circulation

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

Super typhoon Francisco is headed toward Japan as the country is still recovering from typhoon Wipha. The TRMM satellite flew above the western Pacific and caught a good view of super typhoon Francisco on October 20, 2013 at 0947 UTC. A precipitation analysis from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments found that rain was falling at the extreme rate of over 207 mm/hr (~8.1 inches) in an area of violent storms southwest of Francisco's eye. TRMM's Precipitation Radar (PR) discovered radar reflectivity values of over 53dBZ in heavy precipitation south of Francisco

The sixth super typhoon of 2013 called Francisco developed in the Western Pacific Ocean on October 16, 2013. The image on the left was made from data collected as the TRMM satellite passed over on October 18, 2013 at 1002 UTC when super typhoon Francisco was located west-northwest of Guam. A rainfall analysis that used data from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments is shown on the left overlaid on an enhanced infrared image from TRMM's Visible and InfraRed Scanner (VIRS). TRMM PR found that rain was falling at a rate of over 113 mm/hr (~4.5 inches) in powerful

At 1500 UTC (11:00 AM EDT) the National Hurricane Center (NHC) upgraded TD11 to tropical storm Jerry. Tropical Depression ELEVEN (TD11) developed in the central Atlantic Ocean on Saturday September 28, 2013. Southwesterly wind shear reduced TD11's strengthening until this morning. TD11 was having strong bursts of convection when the TRMM satellite flew over earlier at 0929 UTC (~ 6:29 AM Local Time). The image on the left shows a rainfall analysis that uses TRMM Precipitation Radar (PR) data from that orbit. It shows that rain was falling at a rate of over 150 mm/hr from some powerful

Western India has been having intense monsoon rainfall since September 21, 2013. This has resulted in widespread flooding in the west Indian state of Gujarat and reports of at least three related deaths. India had record breaking flooding in the northern state of Uttarakhand in June 2013 with more than 6,000 people killed. Near real-time TRMM Merged HQ/Infrared Precipitation (3B42) data were used in the rainfall analysis above. Rainfall total estimates from these space satellite data for the seven day period from September 20-27, 2013 were used. The highest totals of almost 800mm (~31.5 inches
