Morphology of Rain Clusters Influencing Rainfall Intensity over Hainan Island

Continuous observations from geostationary satellites can show the morphology of precipitation cloud systems in quasi-real-time, but there are still large deviations inversion precipitation. We used binary-connected area recognition technology to identify meso-?-scale rain clusters over Hainan Island 1 June 2000 31 December 2018, based on Global Precipitation Measurement (GPM) Integrated Multi-satellitE Retrievals for GPM data. defined and statistically analyzed parameters reveal typical morphological characteristics clusters, explore relationship between rainfall intensity clusters. found that long axis land were larger than those ocean, continental usually square shape. Rain with a longer concentrated northern side mountains was eastern sides mountains. The variation time more dramatic oceanic 14:00 21:00 April September increased winter. There clear positive correlations area, shape maximum rate. had higher correlation rate establishment helps us understand laws improve prediction this region.
