摘要
本文利用Micaps地面、高空及物理量场的常规资料、卫星云图等,对2019年6月26-27日黑龙江省中北部暴雨天气的成因进行分析,从环流形势、水汽条件、动力特征等方面对暴雨的产生进行讨论。结果表明:西南急流将黄渤海的水汽源源不断地输送至暴雨区;地面的辐合抬升作用及低层辐散、高层辐合提供了较好的动力条件;较长的持续时间是暴雨发生的必要条件。
In this paper,the causes of rainstorm in the middle and north part of Heilongjiang Province from June 26 to 27,2019 are analyzed by using the conventional data of MICAPS ground,high altitude and physical quantity field,satellite cloud map,etc.,and the generation of rainstorm is discussed from circulation situation,water vapor condition,dynamic characteristics,etc.The results show:the southwest jet carries the water vapor from the yellow sea and the bohai sea to the storm area to provide sufficient water vapor conditions;The uplift of the convergence of the ground,the divergence of the lower layer and the convergence of the upper layer provide better dynamic conditions;A longer duration is necessary for a rainstorm to occur.
