Study of 1998 Heavy Rainfall over the Yangtze River Basin Using TRMM Data
用TRMM资料研究1998年长江流域暴雨

TRMM (Tropical Rainfall Measuring Mission) data have been made available to the public users since June 1998. In this paper, some preliminary research is reported for the case study of heavy rainfall over the Yangtze River Basin using TRMM data at 2140 UTC 20 July 1998. TRMM derived precipitation products are also compared with rain gauge observation, ground radar data and numerical model simulation results.It is shown that TRMM data can be easily used to monitor the heavy rainfall and have many applications.
