Abstract :
Using a data clustering method, monthly statistics are calculated from rain rate estimates of the TRMM Precipitation Radar. The statistics show how the following variables change with the size of a rain event: convective rain rate, total rain rate, and convective rain fraction. On average, the convective rain fraction is found to be greatest for small mesoscale events covering 103 km2, while rain rate increases monotonically with the size of the rain event.
