利用Micaps、 NCEP再分析资料、 FY—2C卫星和多普勒雷达等资料， 对2010年6月初广西一次特大暴雨过程进行了分析。结果表明: (1) 850 hPa低涡切变、 500 hPa高原槽和地面静止锋是此次强降雨的主要影响系统。较强的能量锋区、 中低层明显的对流不稳定层结及高层下伸呈漏斗状分布的θse和明显的湿度锋是中尺度对流系统产生的有利天气模型， 而高对流有效位能、 较低的自由对流高度、 较大的低层湿度和垂直风切变， 有利于强降水超级单体的发生、 发展。(2) 贵州西部-河池向东南方向移动的中尺度对流系统（MCS）云团与桂东南西北上的MCS云团在桂中合并后发展为中尺度对流复合体(MCC)， 该MCC在桂中长时间停滞后缓慢东移、 南压是此次过程的主要云图特征。(3) 雷达回波显示， 此次过程期间广西中西部地区形成了大范围的积层混合型降雨回波， 其入流区呈西北—东南向的强回波带上有多个强对流风暴发展， 强回波带前期长时间稳定少变及后期缓慢偏东移造成的\!列车效应\"， 是广西中西部地区出现大范围暴雨—特大暴雨和强雷电天气的重要原因。位于来宾市强降水超级单体风暴属于低质心对流系统， 在发展阶段， 风暴呈超级单体回波钩状结构， 并包含着一个与低层弱回波相联系的前侧“V”形缺口， 相应的径向速度图上出现弱中气旋； 在强盛阶段， 风暴呈波状， 反射率因子由低往高向低层入流倾斜， 其右前侧和左后侧分别存在“V”形缺口， 低层入流位于风暴前侧的“V”形缺口上， 相应的径向速度图上是一个中等强度、 发展成熟的中气旋， 后侧有较强的下沉后侧入流。

Using the CINRAD-SA Doppler radar data， Micaps conventional weather chart， NCEP data， and FY-2C satellite products， a heavy rainstorm produced by mesoscale convective complex in Guangxi in early June 2010 is analyzed. The results show that:  (1) The predominate influencing system of this case is 850 hPa vortex and shear line, 500 hPa plateau trough and surface stationary front. The stronger energy front, obvious convective unstable stratification on middle and lower levels, and the upper-level θse being downward extension and showing funnel-shaped distribution, and apparent moisture front are the favorable weather model of mesoscale convective system, and high CAPE, lower free convection height, high humidity on lower level, high vertical wind shear are favorable to the occurrence and development of heavy precipitation supercell. (2) The MCS cloud of mesoscale convective system slowly moving southeast from western Guizhou to Hechi and the northwestward MCS cloud in southeastern Guangxi combines  in Central Guangxi to develop the mesoscale convective complex, which slowly moves eastward after the long time stagnation, the southward is the main cloud image characteristics in the heavy rainstorm process. (3) Radar data analysis shows that a wide range of laminated hybrid rainfall echo range is formed in central and western regions of Guangxi during the rainstorm process，  which have a lot of convective storm development on inflow side of strong echo belt, and strong echo belt that is stability and few changes of long-time and post-train are important reason to produce heavy rainfall and strong lightning in the central and western regions of Guangxi. The heavy precipitation supercell storm in Laibin is low-quality mind convective system. At the development stage, the storm shows a supercell storm hook echo structure, and contains a low-level weak echo  and associated front ‘V’ notch echo, and a weak mesoscale cyclone in the corresponding radial velocity image; at the strong phase, the storm is wavy, reflectivity factor from low to high inflow to the lower slope,  being ‘V’ notch echo on the right front and left rear side， the lower inflow side in the front ‘V’ notch echo of the storm, and it is a medium strength and well-developed mesoscale cyclone in the corresponding radial velocity image, being strong sinking inflow in the back of the storm.
