地面气象观测中多普勒雷达回波资料的利用

Application of Doppler Radar Echo Data in Ground Meteorological Observations

多普勒天气雷达实时回波通常被广泛应用于短时、临近天气预报、人工增雨(雪)等方面的业务中,事实上,掌握天气雷达回波的演变情况,对做好地面气象观测也是一个很好的辅助工具。通过对2009年4月4日一次强降水过程的多普勒天气雷达云团速度和强度特征分析,结果发现:强降水形成、加强、维持与消散的各个阶段在路径、速度和强度上有明显的体现。

Basing on the Doppler weather radar echo data on April 4, 2009, the speed and strength characteristics of convective clouds were analyzed. The results find that radar echo data in path, speed and intensity are indicative of the various stages （formation, development, maintenance and dissipation） of the heavy rain.
