TRMM

Tropical cyclone Fobane was located southeast of Reunion Island in the southwest Indian Ocean when the TRMM satellite passed over on February 11, 2014 at 0035 UTC. Fobane was very small but contained a few powerful convective thunderstorms near the tropical cyclone's center of circulation. TRMM's Precipitation Radar (PR) measured rain falling at a rate of over 68mm/hr (~2.7 inches) in these storms. The image above shows a simulated 3-D view using data from TRMM's Precipitation Radar (PR) instrument. Those data found a few of the powerful storms near Fobane's center were reaching heights of

The TRMM satellite had an excellent early morning look at Edilson on February 7, 2014 at 0237 UTC (~ 0628 local time) when it passed directly above the tropical cyclone . A rainfall analysis from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments is shown overlaid on an enhanced visible/infrared image from TRMM's Visible and InfraRed Scanner (VIRS). The area covered by TRMM's Precipitation radar (PR) data is shown in a lighter shade. Those data show Edilson south of Reunion and Mauritius Islands dropping it's heaviest rain at a rate of over 175mm/hr (~6.9 inches) in an

Tropical Cyclone Edilson was passing close to the islands of Mauritius and Reunion, in the south Indian Ocean, when the TRMM satellite flew above on February 6, 2014 at 0332 UTC. Rainfall from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments is shown overlaid on an enhanced visible/infrared image from TRMM's Visible and InfraRed Scanner (VIRS). TRMM TMI data showed that moderate to heavy rain was falling at a rate of over 30mm/hr (about 1.1 inches) just to the southeast of Mauritius. With sustained winds of about 55kts (~63 mph), Edilson is much weaker than deadly

Tropical storm Dylan was heading from the Coral Sea toward Australia's Queensland coast when it was viewed by the TRMM satellite on January 30, 2014 at 0214 UTC. The rainfall analysis above used data collected by TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments. Rainfall is shown overlaid on an enhanced visible/infrared image from TRMM's Visible and InfraRed Scanner (VIRS). TRMM's TMI data revealed that moderate to heavy rain falling at a rate of over 31 mm/hr (about 1.2 inches) was preceding Dylan's movement toward the Australian coast. Dylan's approximate past and

The TRMM satellite flew above a tropical low (91S) in the Mozambique Channel on January 28, 2014 at 1011 UTC. TRMM data collected with this pass may be helpful in evaluating this low for possible tropical cyclone formation. An analysis of rainfall from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments are shown on the left overlaid on a visible/infrared image from TRMM 's Visible and InfraRed Scanner (VIRS). TRMM PR measured rain falling at the rate of over 134.9 mm/hr (about 5.3 inches) in a band of powerful convective thunderstorms north of the center of circulation. A 3

People in the southern Philippines are used to heavy rainfall this time of the year but rainfall totals have recently been exceptionally high. A tropical low northeast of Mindanao has been an almost permanent feature on weather maps for the past week. It has caused nearly continuous rain in the area of northeastern Mindanao triggering floods and landslides that have caused the reported deaths of 34 people. The TRMM Multi-Satellite Precipitation Analysis (TMPA), produced at Goddard Space Flight Center, combines the rainfall estimates generated by TRMM and other satellites (3B42). The analysis

Tropical cyclone IAN meandered in an area of the Pacific Ocean between Fiji and Tonga as it intensified from tropical storm intensity with winds of 35kts (~41 mph) on January 5, 2014 to a deadly tropical cyclone with winds of 125kts (~144 mph) on January 11, 2014. Tropical cyclone IAN caused extensive damage and an unknown number of deaths when it passed through Tonga at the peak of it's intensity. The TRMM satellite provided excellent coverage of IAN with multiple passes directly above the tropical cyclone. Rainfall data collected by TRMM's Microwave Imager (TMI) and Precipitation Radar (PR)

Today the TRMM satellite passed above two tropical cyclones in the southern hemisphere. On January 10,2014 at 0117 UTC TRMM had a good daytime view of intensifying tropical cyclone IAN in the south Pacific Ocean east of Fiji with wind speeds over 90kts (~104 mph). Then at 0724 UTC TRMM passed directly above tropical cyclone Colin in the south Indian Ocean that was also intensifying with wind speeds estimated to be above 35kts (~40 mph). Rainfall derived from TRMM's Precipitation Radar (PR) and Microwave Imager (TMI) data was overlaid on Visible/Infrared images from the Visible and InfraRed

Tropical cyclone IAN became the first tropical cyclone of the 2013-2014 South Pacific season when it formed yesterday north of Tonga. The TRMM satellite passed above IAN this morning at 1133 UTC. IAN is a small tropical cyclone but TRMM's Precipitation Radar (PR) instrument found that IAN was dropping rain at a rate of over 113 mm/hr (~4.4 inches) in some areas. Since it was launched on November 27, 1997 TRMM's Precipitation Radar (PR) has been providing 3-D vertical profiles of rain and snow from the surface up to a height of about 12 miles (20 kilometers).
