中文摘要:根据郭晓岚的积云对流加热方法,计算积云对流对MCC加热、增湿的贡献。估计其降水效率,从而推算MCC的降水量。计算结果与实际降水量及降水分布比较接近,可用于MCC6~12h的降水估计和预报。

MCC RAINFALL CALCULATION BASED ON CUMULUS CONVECTION SCHEME
Abstract:Following Kuo’s cumulus convection scheme,the contribution of cumulus convection to heating and humidifying a mesoscale convective complex(MCC)is investigated for itsrainfall efficiency,thereby estimating MCC precipitation, Results show that MCC rainfall calculation based on the developing stage is close to the reality both in quantity and distribution such that it serves to make estimation and prediction of MCCprecipitation for 6~12h in advance.
