| 摘 要： | 本文利用无量纲的台风次级环流方程,用西太平洋地区11年的综合台风资料,计算了热力因子强迫的次级环流。通过计算,得到主要结论如下: 1.非绝热加热和积云热量垂直混合是主要的热力强迫因子,二者的作用具有同样量级。 2.热量的湍流涡旋通量及积云的热量水平输送作用都比较小。 3.Ekman抽吸与积云热量垂直混合是相互促进,共同发展的。有利于次级环流的增强。

| Abstract: | A non-dimensional secondary circulation equation for typhoons has been derived and then 11-yr compositing typhoon data were used to estimate the thermally forced secondary circulation. The main results have been obtained as follows:1.The diabatic heating and Cu vertical heat mixing are major thermal forcing factors. They have the same magnitude of order; 2.The effects of eddy flux and Cu horizontal mixing of heat are of minor importance; 3.Ekman pumping and Cu vertical heat mrxing cooperatively work. This feedback process is favorable for the enhancement of the secondary circulation of typyoons. |
