CINRAD CB产品与自动站资料在人工增雨中的应用

利用高空、地面环流形势图和新一代天气C波段雷达产品中的反射率因子、径向速度产品以及自动站资料,对2011年7月29日大同地区一次大范围降水过程中人工增雨作业条件和效果进行综合分析.在同一环流背景条件下,通过雷达跟踪监测、雷达回波动画显示、作业前后回波强度比较、作业点与未作业点之间的比较,利用自动站数据,对增雨作业的效果进行综合分析比较结果表明此次大范围连续性降水的形成与适宜的人工增雨有一定相关性.

Application of CINRAD/CB and Automatic Station Data to Weather Modification

Based on the circulation patterns in the upper air and at surface, C band Doppler radar products such as reflectivity factor and radar velocity, and automatic station data in Datong, the large area precipitation process on 29 July 2011 is analyzed. The operational conditions for weather modification operation are investigated based on automatic station data. The effect of the weather modification operation is examined scientifically through radar tracking and observing, radar echo animation demonstration, echo strength comparison before and after the operation, and comparison between operation spot and non operation spot, combined with automatic weather station data.The results show that there is certain correlation between the large area continuous precipitation and artificial precipitation enhancement operation.
