The Tropical Rainfall Measuring Mission (TRMM) satellite captured this
image of Typhoon Dujuan just after it had brushed the southern tip of
Taiwan where it was responsible for two fatalities. The image was taken at
22:33 UTC on September 1, 2003. At the time, Dujuan was still
classified as a powerful Category 4 storm with winds estimated at near
135 mph and was moving west-north-west towards the coast of China. The
image gives a top down view of the storm. Rainfall rates from the TRMM
Microwave Imager (TMI) are overlayed on TRMM Visible Infrared Scanner
(VIRS) data (white areas). It shows that all of the deep convection and
heavy rain rates (darker red areas) that are responsible for providing
the heat energy needed to the fuel the storm are present only in the
outer rain bands on the south and east sides of the storm. Susequently,
Dujuan began to weaken as it approached the coast of China.
TRMM is a joint mission between NASA and the Japanese space agency, NASDA.
