摘　　要：分析2003—2015年宁夏人工影响天气作业情况.根据宁夏区域24个气象站1990—2015年日降水资料,用统计方法,对逐年降水量、月降水量、降水日和月雨型占比进行分析,研究26 a宁夏降水分布特征.结果表明,2003年后,大部分月降水量、降水日数增加,小雨、中雨出现的比例增加,大雨和暴雨出现的比例减少.对宁夏人工增加降水作业效果评估有一定的参考意义.The article analyzes the situation of artificial-influence-on-weather operation in Ningxia from 2003 to 2015.It analyzed annual and monthly precipitation,raining days and monthly rainfall pattern with statistical methods according to 24 weather stations daily precipitation data from 1990 to 2015 in Ningxia,and studied its precipitation distribution characteristics.The result shows that,the precipitation and rainy days increase in most months,the proportion of light rain and moderate rain increases,and the heavy rains appear low in proportion.It has certain reference significance on the evaluation on the effect of increasing artificial precipitation in Ningxia.
