摘　　要：本文用一个适合中─β尺度天气系统研究的三维非静力全弹性模式通过对理想环境大气中垂直风切变的不同分布进行数值模拟试验，结果表明：环境风场在风暴的发展演变中具有很大的影响作用，特别是低层民垂直切变值的大小决定了对流风暴的类型和发展演变的主要特征。In this paper, numerical simulation, based on different vertical wind shear distributions in ideal ambient atmosphere, was completed with a three-dimensional, nonhydrostatic and compressible fluid model, Which can be used for research of the meso-β scale weather system. The tentative expermental results show that the environmontal wind can remarkably affect the storm development and evolution,and that the type and main feature of the storm depend Considerably on the vertical wind shear in lower atmosphere layer.
