The seasonal distributions of accumulated rainfall from rain gauges and TRMM 3B42 are shown in Figures 6 and 7, respectively. While the patterns of seasonal rainfall are similar, there are seasonal and regional differences. In the North and South region,the gauge estimates are higher than 3B42. 3B42 is much higher during JJA than the gauge, except for the East region. It is not clear the extent to which the discrepancy is due to the coastal stations in the east region.
