TRMM

Tropical cyclone Rusty's winds had increased to hurricane intensity when the TRMM satellite flew directly above on February 26, 2013 at 0654 UTC. A rainfall analysis derived from TRMM data is shown with the first image. Rain rates in the center of the swath are from the TRMM PR, while those in the outer swath are from the TRMM Microwave Imager (TMI). The rain rates are overlaid on a combination infrared (IR) visible (vis) image derived from the TRMM Visible Infrared Scanner (VIRS). TRMM PR found that the heaviest surface rain was coming down at a rate of over 138mm/hr (~5.4 inches). This

The TRMM satellite passed above an intensifying tropical cyclone in the South Pacific Ocean called Evan on December 11, 2012 at 1759 UTC. Evan is predicted to attain hurricane force winds on December 13, 2012 when it is moving through the Samoan Islands. An analysis of Evan's rainfall from TRMM's Precipitation Radar (PR) and Microwave Imager (TMI) shows that Evan already had an eye-like structure at the time of this TRMM orbit.

High winds, flooding and landslides from heavy rains with typhoon Bopha have caused over 300 deaths in the southern Philippines. The Tropical Rainfall Measuring Mission (TRMM) satellite's primary mission is the of measurement of rainfall in the Tropics. The TRMM-based, near-real time Multi-satellite Precipitation Analysis (MPA) at the NASA Goddard Space Flight Center monitors rainfall over the global Tropics. MPA rainfall totals are shown here for the period from November 28 to December 5, 2012 when typhoon Bopha was moving through the southern Philippines. Typhoon Bopha's track is shown

Typhoon Bopha pounded the Philippines with high winds and drenching rain when it crossed the island of Mindanao today. Numerous deaths and wide spread destruction have been reported. The TRMM satellite had a good view of Bopha moving into the Sulu Sea when it flew over on December 4, 2012 at 1420 UTC. This TRMM pass showed that Bopha still had good organization but Mindanao's rugged terrain had taken it's toll. Bopha's eye had been disrupted but TRMM Precipitation Radar (PR) data revealed that very heavy rain was still falling at a rate of over 85 mm/hr (~3.5 inches) near the center of the

At 0347 UTC today the TRMM satellite flew above a dangerous typhoon in the western Pacific Ocean called Bopha that is a threat to the Philippines. Bopha is predicted by the Joint Typhoon Warning Center (JTWC) to hit the island of Mindinao in the Philippines with winds of 135 kts (155 mph) later today. The first image shows a satellite view of typhoon Bofa with rainfall from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments overlaid on a visible/infrared image from TRMM's Visible and InfraRed Scanner (VIRS). This analysis shows that Bopha had a well defined eye with very

In the United States tornadoes develop most often in the spring when warm moist unstable air accompanies strong fronts and fluctuating upper-air systems. There is a also a slight increase in tornado activity in late October and November. Tornadoes form least often in December and January so the tornadoes that occurred yesterday over the south-eastern United States were unusual. The TRMM satellite was flying over on December 10, 2012 at 1743 UTC (12:43 PM EST) and captured data showing tornado spawning thunderstorms within a frontal system moving through Louisiana, Mississippi, Alabama, Georgia

The TRMM satellite has now been making highly accurate measurements of rainfall from space for fifteen years. TRMM can be used to calibrate rainfall estimates from other additional satellites. Those Rainfall data (3B42) are routinely created and stored at the Goddard Space Flight Center. The TRMM-based, near-real time Multi-satellite Precipitation Analysis (TMPA) at the NASA Goddard Space Flight Center can be used to analyze rainfall over a wide portion of the globe. The TMPA analysis above shows the estimated amount of rain contributed by named tropical cyclones over the western Atlantic in

The TRMM satellite flew above tropical storm Bofa on November 27, 2012 at 1601 UTC and collected data used in the image above. TRMM showed that tropical storm Bofa had an area of very intense convective storms near the center of circulation. TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) data revealed that rain was falling at a rate of over 70mm/hr (~1.75 inches) in that area. TRMM's Precipitation Radar (PR) also showed that powerful storms in the area of the developing eye wall were reaching to heights of about 17km (~10.6 miles).

Beginning this past weekend, parts of central and northern Italy received several days of heavy rain as an upper-level trough situated over western Europe down through the Iberian Peninsula in conjunction with a persistent area of low pressure at the surface over the northern coast of Africa brought a steady flow of warm, moist, unstable air northeastward across the country from the western Mediterranean. A stationary frontal boundary draped across the northern third of the Italian Peninsula provided the focus for showers and storms in that part of the country. The rains caused flooding in
