Abstract:
Distribution and variation characteristics of mesoscale precipitation of tropical cyclones landed in Guangdong are studied with the data of hourly precipitation from satellite and surface observation. The results indicate that the distinct variation of mesoscale precipitation distribution between before and after tropical cyclones landfall occurs. Mesoscale precipitation distribution became more asymmetrical after tropical cyclones landfall varies with time. The mesoscale precipitation distributes quasi-symmetrically near the center of tropical cyclones in 10 hours after landfall. But it happens after 10 hours that mesoscale precipitation distributes asymmetrically near the center of tropical cyclones or far away center of tropical cyclones.
