| 摘 要： | 利用常规气象资料、NCEP 1°×1°再分析资料对阜新地区2013年7月1日和15日2次暴雨过程的物理量场特征进行对比分析，结果表明：副热带高压边缘偏南气流提供了较好的水汽条件；近地面层强辐合高层强辐散的配置增强了大气的抽吸作用，导致暴雨区上空较强的垂直上升运动，利于降水的加强；强降水发生在最大上升速度对应的地方而不是低层上升速度区；近地面层水汽通量和垂直螺旋度的分布与阜新暴雨落区有良好的对应关系；假相当位温大值区或等值线较密集区是暴雨多发区。

| Abstract: | By using the routine meteorological data and NECP 1° × 1° reanalysis data，we carried out contrastive analysis of the physical quantity of two rainstorm weather processes on July 1 and 15 in 2013 in Fuxin. The results showed that the edge of subtropical high southerly airflow provided good vapor conditions．Low-level convergence and high-level divergence field configuration enhanced the pumping effect of the atmosphere and led to strong vertical ascending motion over the heavy rain area. Precipitation occurred in the corresponding zone of local maximum rising speed, not the lower rising speed zone. The storm had a good corresponding relationship with the surface layer of water vapor flux distribution and the vertical felicity in Fuxin, zone of greater value of Potential Pseudo-equivalent Temperature was also prone to rainstorms. |
