中文摘要: 通过对1981～1991年春秋两季孟加拉湾低压影响云南强降水的16个个例的TBB资料进行等值线分析及云顶温度梯度、云降水效率的计算和对中-α尺度对流系统进行了尺度及结构分析、对云顶温度、温度梯度、地理区域与降水关系的分析，给出了一些孟加拉湾低压影响云南并造成强降水时的云图特征量与降水的相互关系。
中文关键词: 孟加拉湾低压，中尺度对流系统，降水
Abstract:By using of the TBB data of 16 cases during 1981-1991,the influence of Bengal Bay depression on the heavy rainfall in Yunnan province was analysed.The isotherm,temperature gradient of cloud top,and the effectiveness of cloud precipitation were calculated.The structure and cloud images of the mesoscale convective system causing heavy rainfall were also analysed.The relationship of the cloud image characters of the depression and heavy rainfall in Yunnan was described.
