利用降水实况数据和NCEP（1°×1°）再分析资料对黄石地区2010年7月11日暴雨过程分别从水汽、热力、动力条件着手进行了诊断分析。分析结果表明：本次梅雨期暴雨的水汽累积过程从10日开始，降水期间上空有水汽通量辐合中心存在，并有低空急流与水汽辐合中心配合；暴雨期间，湿层厚度一直延伸至600hPa：850、700、500hPa的假相当位温θse在鄂东南均超过了350K，且500hPa与850hPa的θse差值为正值，表明该次降水是一次稳定的暴雨过程；暴雨期间中低层形成了明显的θse能量锋区；湿位涡分析表明：湖北黄石处于高温高湿的对称不稳定区，不稳定能量大量释放，产生强烈的上升运动，造成暴雨。

Using precipitation data and NCEP (1°×1°) reanalysis data to make a moisture, heat and power conditions' dagnosis and analysis of a heavy rain process in Huang Shi area on July 11, 2010. The results show that: the water vapor accumulation of Meiyu period rainfall process began on July 10, 2010, there existed a water vapor flux convergence in the center of the presence during precipitation, with a lowlevel jet and moisture convergence center; the wet layer thickness from the ground closed to the height of 600hPa.Generally, when the wet layer thickness reach to the height of 600hPa, it will be conducive to the occurrence of heavy rain; the pseudo-equivalent temperature of 850.700.500hPa in the southeastern of Hubei Province all exeessed of 350K, and the difference of the pseudo-equivalent temperature between 500hPa and 850hPa was positive, indicating this rainstorm was a steady rain precipitation process: and there formed a clear θse energy frontal zone in the lower-troposphere during this heavy rainfall; the analysis of moist potential vorticity showed that: Hubei Huangshi lied not only in a convective instability area including higher temperature and humidity, but also in a symmetric unstable region, the instability of energy released in large quantitis resulting in a strong upward motion, and resulting in heavy rain.
