%X A one-dimensional steady state cumulus cloud model, by considering both cumulus uporaft anddowndraft, has been applied to diagnose the bulk properties inside the cumulus cloud clusters of theMeiyu quasi-stationary front. The vertical structures of several characteristic values of cumulus clouds,e.g. cumulus mass flux, temperature excess, water vapor mixing ratio excess and liquid wate contenthave been studied. The condensation and evaporation processes ofcumulus clusters and the processes ofvertical transports on energies are also discussed. Results show that although the mass flux of ti ie Meiyufront cumulus cloud is larger than that of the tropical deep convective cumulus cloud, but the cumulusclouds of the Meiyu front can only reach a height much lower than the tropical clouds. The 1 frecipitation efficiency in Meiyu front cumulus clouds is about 50%. The vertical flux of latent heat d )minatesthe total energy vertical flux. Its magnitude is greater than that of the tropical disturbance.
