| 摘 要： | 在Ａｎｔｈｅｓｅｔａｌ．的中尺度模式基础上引入胡志晋的双参数层状云模式并重新编制了程序，构成一个包含三种水相态和比较详细云物理过程的三维层状云系模式。为保持在较长时步中计算的稳定和精度，对微物理过程的计算采用混合格式，少数过程采用时间分裂格式，在相变过程的处理上设计了同时计算不同相态相变的参数化方案，按Ｌａｇｒａｎｇｉａｎ方法设计了粒子下落格式。用干模式、积云参数化模式、两相显式模式和本文模式对两个中尺度低涡个例作了模拟，对比分析不同模式的模拟能力。结果表明本文模式对涡环流结构、云场和降水分布的摸拟比其他模式更合理，更接近实况。

| Abstract: | three dimensional model of stratiform cloud system is constructed by mesoscale atmospheric model of Anthes et al. and two-parameter stratiform cloud model of Hu et al. which include three phases of water and detailed cloud microphysical processes. The hybrid-scheme and the time-split scheme are used for calculating the microphysical processes. A Lagrangean scheme is designed for calculating the falling of particles. The simulated results of 2 mesoscale vortex cases using this model are analyzed and compared with other models. It is shown that more resonable simulated structures of circulation, cloud system and surface precipitation can be given by this model. |
