Typhoon Rumbia had weakened to a tropical storm and moved over southern China when NASA’s TRMM satellite flew above on July 2, 2013 at 0316 UTC and measured its rainfall rates.

An analysis of rainfall from TRMM Microwave Imager (TMI) and Precipitation (PR) data shows that Rumbia was dropping rain at a rate of over 92mm/hour (~3.6 inches) in areas of southern China near the Gulf of Tonkin. An intense but narrow feeder band near Hong Kong is shown streaming heavy rainfall into China from the South China Sea.

An image showing a 3-D slice through of tropical storm Rumbia was created at NASA’s Goddard Space Flight Center in Greenbelt, Md. using TRMM Precipitation Radar data. Those data showed that the thunderstorms nearRumbia’s center of circulation were then reaching heights mainly below 13 km (~8.1 miles). Some powerful thunderstorms in the feeder band near Hong Kong were found to reach to heights of 15 km (~9.3 miles).
