利用常规气象观测资料和NCEP1°×1°再分析资料，对2011年6月22-23日豫南暴雨过程进行分析，结果表明：此次河南区域暴雨是由高空后倾槽、中低层冷式切变线以及西路冷空气共同影响所致。夏季冷式切变线暴雨的低层有明显北风冷垫作用，水汽主要来源于对流层中低层。水平螺旋度的变化对天气系统的移动和发展具有较好的指示作用；垂直螺旋度的变化对降水的落区和强度预报具有较好的参考价值；暴雨区主要发生在高螺旋度与较高对流有效位能（h垂直〉10×10-8hPa·s-2、CAPE〈1500J·kg-1）相配合的环境中。

Based on the conventional meteorological observational data and NCEP 1°×1° reanalysis data, the weather process of regional heavy rain occurred in the south of Henan from 22 to 23 June, 2011 were analyzed. The main conclusions are as follows. The backward-tilting trough in the middle and high levels, cold shear-line in the middle and low level and the west path of cold air in the surface are the mainly influence systems. One of the causes of rainstorm for cold shear-line is the cold pad caused by the north wind in the low level. The main source of water vapor is in the middle-low level. Changes in the horizontal helicity can reflect the movement and development of the mainly influence system ; and changes in the vertical helicity has a good reference value on the forecast of rainfall area and precipitation intensity ; heavy rain areas are in the energy environment of the largest helicity compatible with larger convective available potential energy（hvertical〉 10 × 10-8 hPa · s-2, CAPE 〈 1500 J · kg-1）.
