摘要
利用2001年1~12月TRMM月降水量产品与我国622个台站的降水观测结果,分析了这2种资料所描述的我国降水分布的异同。结果表明,TRMM和地面站点观测的我国降水的空间分布形式大致相同,均能反映出我国降水的空间分布特征和季节变化特征,但2种资料在降水极值和极值区域范围大小等细节上仍存在一定差异,因此在使用TRMM数据前应该对其进行适当订正。
The TRMM monthly rainfall data and the monthly rainfall records observed by 622 stations in the mainland of China during the period from January 2001 to December 2001 were used to analyze similarities and differences of the precipitation in China.The comparisons indicated that the TRMM data is not obviously different from the observed data.They both can reflect the spatial distribution and seasonal variation of precipitation.However,there are still some differences in the extreme precipitations and the corresponding regional sizes.Therefore,we should make the appropriate revisions to the TRMM data before using it.
