| 摘 要： | 本文对1957年12月16—20日我国东北地区的一次强烈的气旋发展过程进行了三度空间分析.分析结果指出:由气旋初生一直到填塞,在气旋中心上空各層等压面(200mb 以下)间均出现上升运动,并且在沒空气区域內也几乎全是上升运动.随着气旋的发展,中心上空的上升运动以及辐散辐合的量都一直在增强,无辐散面的高度逐渐下降并趋于对称,当冷空气南下时,在冷堆南部上升运动最强,因而使这部份的冷堆向上延伸,这是促使高空孤立冷涡形成的主要机构.此次气旋內的降水集中在冷堆內,并不像一般冷涡一样只限于冷堆的东南部。

| Abstract: | In this papor throe-dimonsional analysis of an intonsely developed cyclone in Northeastorn China in Dec. 10 to 20 1957 is presontod. It is found that at all levels in the center of this cyclono there is ascending notion daring the development. Within the cold dome, there is also ascending motion at all levels. Accompanying development of this cyclone, the ascending motion, divergence and convergence over the center are intensifing, and the level of non-divergence subsides and tends tojvards symmetry. |
