摘    要:中尺度对流复合体(MCC)会给华北平原带来暴雨灾害。在对MCC普查的基础上,选取发生在华北平原上的3个典型个例合成出代表MCC发生前的环境场,并通过诊断分析考察了华北平原发生MCC的条件。结果表明,华北平原发生MCC的环境既不同于我国南方的MCC,也不同于北美。对于具有明显夜发性的MCC,所得到的MCC发生环境和条件,对预报当天傍晚华北平原是否有MCC发生有一定的参考价值。

关 键 词:中尺度对流复合体(MCC)    合成    发生条件

Abstract:The Mesoscale Convective Complex (MCC) can generate the torrential rainfall in the North China Plain. The composite synoptic environment before MCC genesis is obtained based on three typical MCCs selected from the general investigation of MCCs in the North China plain. Through diagnoses and analysis, the conditions of MCC development over North China plain are investigated. The results reveal that the synoptic environment of MCC development in North China plain is neither the same as in South China nor in North American. Since MCCs often occur at night, the results about the environment and conditions for MCC development are helpful in forecasting whether MCC will occur in the early evening of the day over the North China plain.
Keywords:Mesoscale Convective Complex (MCC) Composite analysis Development conditions
