Click here to view higher resolution version TRMM Eyes Tornadic Thunderstorms There were more than 65 tornadoes reported in the Oklahoma, Texas and Kansas area by late wednesday March 28, 2007. The images above are from TRMM data captured as the satellite passed over this area on Thursday March 29 at 2035UTC (3:35 PM local time). This was close to the time (4:20 PM) that a tornado touched down in northwestern Oklahoma City. The main image above shows the horizontal distribution of rain intensity looking down on these storms. Rain rates in the center of the swath are from the TRMM Precipitation Radar (PR), while those in the outer portion are from the TRMM Microwave Imager (TMI). The rain rates are overlaid on infrared (IR) data from the TRMM Visible Infrared Scanner (VIRS). The image inset at the bottom was made from data taken at the same time and shows a 3D view of the storms courtesy of the TRMM Precipitation Radar (PR). The Tropical Rainfall Measurement Mission (TRMM) satellite uses it's Precipitation Radar (PR) instrument to measure precipitating ice and rainfall inside clouds. The colors indicate the relative height of rain cells (15 dBZ echo surface) embedded within the storms.
TRMM is a joint mission between NASA and the Japanese space agency JAXA.
