一次冷锋降水过程消(减)雨催化试验

利用常规探空资料,结合雷达、卫星及自动站资料对2009年9月19-20日十一运会人工消(减)雨地面作业演练进行了分析。这次过程是一次比较稳定的小到中雨天气过程,为人工消(减)雨作业试验提供了有利的条件,通过9月19日晚系统前期和20日上午消(减)雨作业过量催化试验,对比分析作业前后的资料特别是直观的雷达探测资料,进行人工影响天气效果的物理检验,取得了比较明显的作业效果,为以后的消(减)雨作业催化试验提供了有益的尝试。

Seeding Experiment on Artificial Rain Reduction during a Cold-Front Precipitation Process

Combining the conventional sounding data with from radar, satellite, and the automatic weather station data, an analysis is made of the surface operation drills of artificial rain reduction during the 11th Chinese National Games between 19 and 20 September 2009. It is a relatively stable process with small to moderate rainfall, which provided good conditions for the experiments of artificial rain reduction. Based on the two excessive seeding experiments in at the night of 19 September and the morning of 20 September, the contrast is conducted between the radar data before and after operation. At the same time, the physical examination for the effect of weather modification is carried out. The results proved satisfactory, which can provide useful references for further weather modification experiments.
