TRMM Has Second Look At Typhoon Krosa
On November 1, 2013 at 1320 UTC the TRMM satellite had the second look at typhoon KROSA. KROSA weakened slightly when it passed over the northern Philippines but had started to intensify with this second pass over the South China Sea. The image on the left shows rainfall data collected by TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments overlaid on an enhanced infrared image. TRMM PR data revealed that rain was falling at a rate of over 116mm/hr (4.5 inches) in KROSA's eye wall. Radar reflectivity values greater than 50dBZ were found in the same area.
The 3-D perspective view on the right shows KROSA's vertical structure based on radar reflectivity data from the TRMM Precipitation Radar (PR) instrument.
