黄河流域极端降水特征分析OACSCDCSTPCD
Analysis of characteristics of the extreme precipitation in the Yellow river basin
利用黄河流域1965-2012年252个观测站日降水资料，分析了黄河流域年极端降水、汛期日极端降水的时空分布特征。研究结果表明：黄河流域年极端降水在空间分布上呈现出从东南向西北递减的特点，不同区域的年极端降水强度有显著空间差异，下游大汶河年极端降水强度最大，内蒙杭锦后旗临河一带年极端降水强度最小。极端降水站数偏多的年份，该年黄河流域总降水量也趋于偏多。汛期日极端降水强度从黄河上游到下游逐渐增强，主要发生在7-8月。
Based on the daily precipitation data in the 252 observational stations from 1965 to 2012 in the Yellow River Basin, the temporal-spatial distribution characteristics of annual and daily flood season ex-treme precipitation were analyzed. The results showed that:the spatial distribution of annual extreme pre-cipitation reduced gradually from southeast to northwest of the Yellow River Basin. There were significant spatial differences in the intensity of annual…查看全部>>
