| 摘 要： | 利用常规气象观测资料、自动站资料及卫星资料，从大尺度环流背景和水汽、动力、热力条件出发，对2013年8月底东北冷涡影响下秦皇岛两次降水过程进行对比分析。结果表明：由于处在东北冷涡发展的不同阶段，中低层温度场配置不同，两次过程降水特点极不相同。8月27日降水是一次连续的区域性降水过程，以层状云降水为主，降水均匀连续，8月31日至9月2日是冷涡后部西北气流影响下的数日局地性对流降水，具有很强的突发性。

| Abstract: | Using conventional meteorological observation data, automatic station data and satellite data, by analyzing the large scale circulation background, the water vapor distribution, dynamic and thermal conditions, two rainfall processes were analyzed under the background of northeast cold vortex in late Aug 2013.The results showed that the presentation of two rainfalls have obvious difference because there are different configuration in the temperature field of low-middle layer in the different developing stages of cold vortex. A regional continuous rainfall took place on august 27, it presented the characteristic of stratiform cloud rainfall, and being stable and continuous. The rainfall from August 31to September 2 can be determined scattered local convective rainfall with uncertain nature in several days due to the impact of northwest airflow in back of the cold vortex. |
