摘要
根据江西省2007-2008年人工增雨作业记录和南昌多普勒天气雷达产品资料,选取了621个人工增雨作业样本,运用统计和对比的方法对样本进行分析,获得江西省人工增雨作业条件的低层反射率、组合反射率、回波顶高、垂直积分液态水含量等参数指标,并建立人工增雨作业条件判别方程。
According to 2007—2008 rainfall enhancement operation records and Nanchang Doppler weather radar products of Jiangxi,621 rainfall enhancement samples were selected.Using statistical and comparative methods,these samples were analyzed and the indexes of reflectivity,composite reflectivity,echo top,vertical integrated liquid,etc.were obtained.The equation for differentiating rainfall enhancement condition was built up based on these indexes.
