| 摘 要： | 本文内容分两部分: 1.对一次江淮切变线形成过程中一些物理量的演变作了计算并分析,讨论了这些量变化的原因,着重讨论了地形某些动力作用的贡献,作者强调地形边界的摩擦效应对局部环流演变的影响。 2.应用一层和三层准无辐散模式进行了理想的和实际的初始流场的数值预报试验,得到能反映出实际切变线形成过程特点的一些结果。

| Abstract: | The process of the low level shear line formation over China during 17 to 19 June 1960 is investigated by calculating and analysing some of its physical factors. Some dynamical influences of the Tibetan plateau are estimated quantitatively. The orographic friction effect seems to be important for the evolution of the local circulation. Tentative numerical-experiments for the formation of shear line are made with one-and three-levels quasi-nondivergent models, starting with ideal and actual initial flow distributions. The processers calculated are similar to that of the actual shear line formation in the main respects. |
