华南地区几种降水产品的对比分析
|
摘要
对华南地区3种比较常用的降水产品(CMAP、GPCP、TRMM)进行了比较和分析。结果表明,在华南地区,这3种降水产品测出的降雨量在空间上具有一致的大尺度分布特征,在时间演变上具有一致的演变趋势,都能很好地反映雨带的季节性迁移特征和华南汛期的降雨特征;但是在不同的具体区域,三者的细节特征差异还是比较显著的,相比较而言,GPCP和TRMM具有更为一致的空间分布特征;在地形复杂的区域,TRMM具有更良好的表现能力。
Three precipitation products widely used in south China( CMAP,CPCP and TRMM) are compared and analyzed. The results are shown as follows. The three products are all able to show consistent large-scale spatial distribution and temporal evolution trends in the amounts of rainfall in this region and reflect seasonal migration of rainbands and precipitation characteristic of the raining season in south China.Significant differences remain,though,in detailed characteristics for different parts of the region. While CPCP and TRMM are better in capturing consistent spatial distribution,TRMM performs better in reproducing features in regions with complicated terrain.
