利用常规观测、加密自动气象站以及NCEP/NCAR再分析资料，分析了抚顺2014年6月16—18日的暴雨过程。结果表明，此次暴雨过程是一次连续性降水过程，具有雨量大、持续时间长、范围广等特点，且降水分布比较均匀。地面倒槽、低层切变线和高空冷涡是形成暴雨的主要影响系统。此次降水无明显低空急流，850 hPa切变线为降水提供了动力条件，风速辐合为降水提供了水汽条件，同时低层具有较大的比湿和相对湿度场，水汽通量散度值表明水汽输送较好。此次暴雨抚顺地区有较大的K指数和对流有效位能（CAPE），850 hPa有θse高值区，反映不稳定能量条件较好。

This paper analyzed a rain-storm process in Fushun during June 16—18 in 2014 according to the data from conventional observation, encrypted automatic weather station and NCEP/NCAR reanalysis data. The results re-vealed that this rainstorm lasted for a long time and affected an extensive area. The heavy precipitation was evenly dis-tributed in Fushun region. A low-level inverted trough, a low-level shear line and a high-altitude cold vortex were the weather systems determining the forma-tion of the rainstorm in Fushun. As there was no obvious low-level jet, the shear line at 850 hPa and wind speed conver-gence provided the power and moisture conditions for this precipitation, respec-tively, while the high specific humidity and relative humidity at low altitude pro-vided suitable water vapor conditions. The water vapor flux divergence values also proved better circumstance for the transfer of water vapor. The high K in-dex, strong convective available potential energy (CAPE) and high θse areas all proved the better conditions of unstable energy during the rainstorm in Fushun region.
