TYPHOON NEOGURI HEADS TOWARD SOUTHERN CHINA

KML ( SHOW IN GOOGLE EARTH)
Typhoon Neoguri, the first typhoon of 2008 in the western Pacific, is shown in the image above as it was heading toward the Chinese island of Hainan. The Tropical Rainfall Measuring Mission (TRMM) satellite flew directly over Neoguri at 0729 UTC on the 17th of April and captured those data that were used to make the image above. Neoguri was a category 2 typhoon with wind speeds of about 90 knots (104 mph) when viewed by the TRMM satellite. Neoguri weakened as expected after hitting Hainan but three persons were killed due to strong winds and a mud slide caused by tropical storm Neoguri as it came ashore in South China's Guangdong province. Neoguri formed into a tropical depression on the 14th of April over the Sulu Sea in the southwestern Philippine islands. The TRMM image above provides a "top down" view of Neoguri showing rainfall rates within the typhoon from the TRMM Precipitation Radar (PR) in the inner swath and the TRMM Microwave Imager (TMI) in the outer swath overlaid on Infrared (IR) and Visible (VIS) data from the TRMM Visible Infrared Scanner (VIRS).

TRMM Precipitation Radar data received at the same time as the "top down" view were used to make the 3-D image shown just above. This image shows the vertical structure of typhoon Neoguri with powerful thunderstorm towers seen reaching to above 15km (9.3 miles) in the eye wall of typhoon Neoguri.

The Tropical Rainfall Measuring Mission (TRMM) is a joint mission between NASA and the Japan Aerospace Exploration Agency.
