ABSTRACT
The data from the Tropical Rainfall Measuring Mission (TRMM) satellite has provides valuable information for tropical cyclone (TC) research. In this study, the convective rainfall properties of the TCs are analyzed by using TRMM data. The convective and stratiform regions in the TCs are associated with high- and low-intensity rainfall, respectively. The convective regime is characterized by the release of significant amount of latent heat at all heights in the troposphere compared with the stratiform regime, where cooling is observed at lower height (~1–2 km). The stratiform region covers a very large area compared with the convective regime. The vertical cross-section of the convective towers reached up to the height of 16 km. High reflectivity of up to 55 dBZ and the corresponding rain of around 120 mm/h were observed. The maximum value of occurrence is 20 mm/h.
Key words: Tropical Rainfall Measuring Mission (TRMM); tropical cyclone (TC); rainfall; radar reflectivity.
