摘　　要：以2013年2月17日-19日的一次人工增雨过程为例，详细分析了人工增雨数值模式产品对人工增雨作业的指导作用，认为模式产品能够给出未来24小时内的人工增雨作业条件，其24小时降水分布与地面降水实况非常相近，其柱云水量分布与卫星云图、雷达回波非常相似。利用模式每3小时的降水量、柱云水量和柱过冷云水量，可以分析出人工增雨作业条件较好的区域和时段，对人工增雨作业具有很好的指导作用。This paper investigated the application effects of rainmaking - model products on the operation of artifi- cial precipitation enhancement, based on a case study duringl7 - 19 February 2013. The study suggested that the model products could provide the rainmaking operation conditions for the next 24 hours, as the forecasting rainfall in the next 24 hour was similar to the actual distribution and the forecasting column cloud water content also resembled the images from satellite and radar. The optimal areas and periods could be ascertained by the model 3 - hour products of rainfall, column cloud water content and column supercooled cloud water content, which would play a guiding role in the operation of artificial precipitation enhancement.
