利用常规气象观测资料,区域自动站逐时资料和多普勒雷达资料,以及NECP/NCAR再分析资料等,对2012年6月27日石嘴山市降水天气过程进行分析。分析表明,500hPa高空槽过境为降水提供较好的冷空气条件；500hPa来自孟加拉湾的西南暖湿气流和700hPa的偏南风急流带为降水提供较好的水汽条件；地面气压场的倒槽形势也为低层的辐合上升提供动力条件。

Using the conventional meteorological data and regional automatic station hourly data and Doppler radar data, and reanalysis data of NECP/NCAR , a rain weather process occurred during June 27, 2012 in ShiZuishan was analyzed.Analysis shows that the upper trough at 500hPa provides cold air condition for precipitation ; the warm wet air in the southwest current at 500hPa witch is come from the bay of Bengal and partial southerly jet at 700hPa provide fine water vapor conditions for precipitation;surge chamber at ground pressure situation for the low layer convergence rose provide dynamic conditions.
