摘要:
利用山东省22个基本（准）气象站1981-2017年汛期（6-9月）逐日降水数据，运用降水集中度指数Q，统计分析了山东汛期降水分布的时空变化特征，并分析了有效降水、强降水和极端降水等不同强度降水日数和降水量的分布特征和变化趋势。结果表明：鲁中山区至鲁东南一带汛期Q指数相对较小，降水相对均匀，山东半岛北部沿海和鲁西地区汛期Q指数相对较大，降水相对集中。山东省中西部大部分地区Q指数呈减小趋势，降水量和降水日数多为增加趋势，山东半岛沿海地区Q指数呈增加趋势，降水日数减少，降水呈更为集中的趋势。大部分地区不同强度的降水量和降水日数呈增加趋势，山东半岛沿海地区强降水和极端降水日数增加趋势更为明显，会导致该地区降水更加集中。
Abstract:
Based on daily precipitation data at 22 basic meteorological stations in Shandong Province during the period from 1981 to 2017, the changes in distribution of precipitation in flooding season in Shandong Province were comprehensively analyzed using the concentration index(Q), and spatial-temporal distribution characteristics and changing trend of different grads precipitation were analyzed. The results indicated that the regions with smaller Q indexes were middle Shandong and south-east Shandong and the areas with the bigger Q indexes were northern coast of Shandong Peninsula and western Shandong; the Q indexes presented the decreasing trends in most regions of middle-west Shandong and increasing trends in coast regions of Shandong Peninsula; the total amount of precipitation and days precipitation in most regions presented the increasing trends; days of strong and extreme precipitation were more obvious and precipitation was more concentrated in coast regions of Shandong Peninsula.
