These are images of concentrated heavy rain over Korea observed by TRMM Precipitation Radar (PR) on July 31, 1998 during the period 10:12pm to 10:16pm (JST). The heavy rain front in middle and eastern China moved to the east without weakening, bringing great damage, landslide casualties, and muddy streams to the southern part of Korea. According to the newspaper, the highest recorded precipitation was 226 mm in Soon Cheon, Cheon Ra Nam-Do. 202mm of precipitation occurred in San Cheong, Kyung Sang Nam-Do, and 103mm in Hae Nam, Cheon Ra Nam-Do. These precipitation estimates are for the night of July 31 up to 7pm on August 1. A record Korean precipitation rate of 128 mm/hour was also observed in Soon Cheon, Cheon Ra Nam-Do.
The left image shows the horizontal distribution of rain at an altitude of 2.0km. The right image shows the vertical cross section of rain. This example highlights the fact that with TRMM PR it is possible to observe rain rates at different heights in precipitation system. In this case, the image presents rain rate information for different heights along a 14km vertical column.
