从天气实况和环流特征入手,并以各家数值预报为主要的预报依据,对通辽市某次降水过程进行了认真的分析,通过分析得出此次天气过程是高空冷槽与地面倒槽共同作用产生的降水,因系统深厚,移动缓慢,有大范围由南向北的水汽输送和辐合,使过程降水量大,持续时间长.

From the aspect of weather observation and circulation features and based on various numerical predictions, this paper analyzes the precipitation process in detail, reaching a conclusion that the precipitation process is a combined action because of upper cold trough and surface inverted trough. Because the deep system is moving slowly and a wide range of moisture is also transporting and converging from south to north, it rains quite heavily and the process lasts for a long time.
