| 摘 要： | 利用天气实况和NCEP再分析资料,对2010年7月19～22日辽宁区域性大暴雨、局部特大暴雨天气过程进行了分析。结果表明,副热带高压稳定偏北是发生这次强降水过程的根本原因;西南涡北上为过程提供了充沛的水汽和热力辐合抬升条件,冷空气东移南下为过程提供了动力抬升条件;暴雨与高能舌有很好的对应关系,总能量分布对暴雨的落区有很好的指示作用。

| Abstract: | Based on the observational data and NCEP reanalysis data, a heavy rain process on July 19 to 22, 2010 in Liaoning Province was ana- lyzed. The results showed that, the subtropical high stable north is the root cause for occurrence of the heavy rainfall. Southwest Vortex northward provided abundant water vapor and thermodynamic convergence lifting conditions, cold air eastward and southward provided dynamic lifting condition. The heavy rain mainly distributed in the tongue area of high energy, the total energy is a key index to predict the rainfall area. |
