How to separate the outgoing wind and precipitation from trmm
Based on the rainfall radar PR and TMI data of TRMM (Tropical Rainfall Measurement Mission), the three-dimensional structure characteristics of precipitation and various water particles in the development, maintenance and attenuation stages of Typhoon Nasha in 2005 were studied in detail. Through analysis, it is found that (1) most areas of typhoon precipitation are stratiform precipitation, but they contribute greatly to convective precipitation. (2) The average precipitation and the horizontal distribution of various water particles are also very different in different stages of the typhoon. In the development stage and maintenance stage of typhoon, the maximum water particle content is basically the same as the maximum average precipitation, that is, the maximum wind speed radius. (3) In different stages of typhoon, the average vertical profiles of various water particle contents are similar. The height of the maximum content of water particles in precipitation cloud system is related to the type of water particles.
