| 摘 要： | 利用常规观测资料、NCEP再分析资料、卫星资料、雷达以及区域自动气象站资料对2012年8月3~4日桓仁地区大范围强降水的形成和演变特征进行分析。结果表明,此次大暴雨过程是副热带、西风带、热带系统共同作用的结果。200 hPa高空急流入口区与低空急流出口区相叠,有利于上升运动的维持和发展;大暴雨发生在低空急流核的前方,水汽通量高值区与强水汽辐合中心重合处,并与850 hPa以下θse≥345 K的高值舌区有很好对应关系。

| Abstract: | Using the conventional observation data during Aug.3-4,NCEP reanalysis data,satellite data,radar and automatic weather station data,the formation and evolution characteristics of the large-scale heavy precipitation in Huanren County during Aug.3-4,2012 were analyzed.It was obtained that the process of the heavy rainfall subtropical westerly belt,the result of tropical systems.200 hPa jet stream entrance area stacked with low-level jet exit area,in favor of the maintenance and development of upward motion; heavy rain occurred in the front of low-level jet nuclear,high values of water vapor flux coincides with strong moisture convergence center,and has good correspondence with the following 850 hPa θse ≥ 345 K high values tongue area. |
