环境大气对积云发展的影响

为了能更实际客观地模拟天气的发展变化，在胡志晋教授的一维时变积云数值模式的基础上考虑了环境大气与积云群的发生、发展及降水之间的相互作用，保留了原模式所有的微物理过程，建立了一维积云时变套柱模式。此模式不仅能模拟积云，还可以模拟积云在层状云中发展变化，以及模拟环境大气具有辐合辐散场时积云的发展。

Effect of Environmental Atmosphere on the Development of Cumulus

A one-dimension cumulus time-varying support and guided cylinder model is established in order to simulate more objectively the development and change of weather on the basis of one-di- mension time-varying cumulus numerical model, of which all the micro-physical process are kept, invented by professor Hu Zhijin, taking into account the interactions among environmental atmo- sphere, the generation and development of cumulus group and raining. This new model can not on- ly simulate cumulus, but also the development and change of cumulus in sheet cloud, as well as the development of cumulus when there is convergence and divergence fields in the environmental atmospbere. It is valuable in simulating weather development.
