地形和下垫面性质对降水时空分布的影响

摘要

According to the precipitation data of Naiman Meteorological Bureau and Qinglongshan Meteorological Bureau from 1971 to 2010, effects of land and underlying surface properties of two different locations of the linear distance of less than 50 km on the spatial and temporal distribution of precipitation were analyzed and compared. Results showed that there were differences in the year, month and ten days average precipitation, and the emergence times of their change range and extreme value were different.%根据内蒙古奈曼旗气象站和青龙山气象站1971—2010年的降水资料,对比分析了直线距离小于50km的两地不同地形和下垫面性质对降水时空分布的影响。结果表明,降水年、月、旬平均值均存在差异,变化幅度及极值出现时间各有不同。
