【摘要】 本文通过利用雷达资料对2016年7月9日发生在大同地区的一次增雨过程进行了详细分析。结果表明:速度图上出现辐合流场与强降水落区有着很好的对应关系,气流汇合的区域对应着降水量大值区。低层到中层显著的暖平流,为降水提供了丰富的水汽条件,气流汇合区域和零度层亮带可为人工增雨作业时机和部位提供可靠依据。因为气流汇合区域中的上升气流会把催化剂带到云中去,有利于催化的发生。更多还原

【Abstract】 Based on the C-Band radar data are used to analyze a process of increasing rain in Datong area on July 9, 2016. The results show that the convergence flow field on the velocity map has a good relationship with the heavy precipitation area, and the area where the airflow merges corresponds to the high precipitation area. The significant warm advection from the lower to the middle level provides abundant water vapor conditions for precipitation, and the air convergence area and the zero level bright zone can provide reliable basis for the timing and location of artificial rain increase operations. Because the updraft in the confluence area will bring the catalyst to the cloud, which is conducive to the occurrence of catalysis.更多还原
