| 摘 要： | 利用华东地区97个气象站点,1998—2012年逐月降水资料和TRMM卫星降水产品,基于卫星结合雨量计降水估算方法,并考虑海拔高度对降水的影响,对华东地区的降水进行估算,得到研究区域降水的时空分布情况。通过误差验证,发现估算值与站点实测值之间具有较好的一致性,并且1、4、10月的估算值要好于7月的估算值。总体而言,该方法能够对华东地区进行较好的降水估算,并且能够反映研究区域的降水空间分布情况。

| Abstract: | Using the monthly rainfall data from 97 meteorological stations in east China and TRMM satellite precipitation products during 1998-2012, the spatial and temporal distribution of precipitation in research reigon was found by estimating the precipitation in east China and considering the influence of altitude on rainfall, based on the satellite and rain gauges combination method. Validation results show that estimation value was consistent with the measured one at relevant sites, and estimation in January, April and October were better than that in July. Overall, this method is available to estimate the precipitation in east China and to decrible spatial distribution of precipitation better. |
