中文摘要:
      采用比较完全的ω方程,计算了暴雨期间大范围垂直运动场。指出导致各种天气过程与垂直运动大小的关系以及水汽凝结潜热的突出影响;得到了登陆台风和暴雨区的三维运动图案。另外,对于用某些天气学分析的结论,如弱冷空气活动、东风气流和上游热带涡旋等对暴雨的影响,用定量计算的结果给予澄清和肯定,揭露了台风反覆转向时垂直结构的变化。最后,给出了暴雨预报的着眼点。
英文摘要:
      During the heavy rain period, the large-scale vertical velocity is computed using the compaxatively complete co-equation. It is shown that the item of latent heat is the most important in various vertical velocity producing processes. The three-dimensional motion pattern through the central part of no. 3 typhoon, 1975, and the heavy rain area are shown. Some of the synoptical analysis conclusions for heavy rain, such as weak cold air and east air flow as well as tropical vortices upstream, are affirmed by the computed results. The variation of the structure of typhoon during the period of changes of direction of motion is shown. Finally, a scheme for prediction of of the heavy rain is proposed.
