β效应和移动性CISK波与南亚夏季风槽脊的活动

Movable CISK Wave with β Effect and the Behavior of South Asia Summer Monsoon Trough-Ridge

因此，可以初步认为β效应和CISK机制对南亚夏季风槽脊的活动具有极其重要的作用。

So the conclusion can be made that both of β effect and CISK mechanics may play a very important role in the behavior of South Asia summer monsoon .

在取南亚夏季风区平均大气参数情况下的计算结果表明，这种移动性CISK波可以解释南亚夏季风槽脊活动的一些基本特征。

The calculations with the mean atmospheric parameters over the South Asia summer monsoon region show that the main features of the behavior of South Asia summer monsoon trough-ridge may be explained with such movable CISK wave .

中国东部冷槽和热脊形成机制分析

Analysis on the formation mechanism of the cold trough and the thermal backbone in east of China

结果表明：当小槽、小脊的波长变长时，其振幅（能量）增大，扰动发展；

The main results are as follows : when the wavelength of small trough or ridge is enlarged , it 's amplitude increases and the disturbance develops .

例如，极涡向北欧偏移，东亚、北美大槽和阿拉斯加脊的维持，都与地形有密切关系。

For example , the movement of the Arctic vortex to northeurope , the maintained troughs over East Asia and North america , and the maintained ridgeover Alaska are closely related to the relief .

The equations is used whether roller is column or cone , cam is in spine or groove location , left or right helical , single head or many heads and how it is turning .

在非线性近似下，可形成孤立波槽和孤立波脊。

Under the nonlinear approximation solitary wave troughs and solitary wave ridges are formed .

二级近似时其解为孤立波形式&不稳定时，在地形不同位置可形成东移或西移的孤立波槽或孤立波脊；而在稳定时只形成孤立波槽。

Under second order approximation both troughs and ridges of unstable isolated waves are formed in different locations , and for stable isolated waves only troughs are formed .
