Abstract:
Distribution and variation characteristics of mesoscale precipitation of tropical cyclones landed in Hainan during 1996-2005 are studied with the dat a of hourly precipitation from satellite and surface observation. Based on the d ifferent moving pathways, the landing cyclones can be divided into four major ca tegories. The analysis of four different types in seven cases indicates that the re is a distinct variation of mesoscale precipitation distribution before and af ter tropical cyclones landfall. The results show that the mesoscale precipitatio n distributes quasisymmetrically near the center of tropical cyclones in 10 hou rs before landfall，but after 10 hours mesoscale precipitation distributes asymmetrically near the center of tropical cyclones or far a way center of tropical cyclones. The intensity variation of maximal precipitation center is obvious during the la ndfall course.
