| 摘 要： | 考虑了经向风应力和纬向风应力联合作用下热带大洋的响应问题.结果表明，只有一阶的经向风应力或具有辐合辐散的经向风应力才对最后的速度场和位势场造成影响.零阶的扰动温跃层和纬圈流受风应力的直接驱动和Kelvin波、Rossby短波的影响，而Rossby短波由经向风应力直接造成；二阶模则受风应力的直接驱动和Rossby短波的作用，同时经向风应力也产生了附加的Rossby短波.另外，在西边界处存在很强的暖水补充到赤道的现象，经向风应力有使暖水向赤道输送的作用，而西风应力使西边界处的暖水向东输送.

| Abstract: | The synchronous response of tropical ocean to meridional and zonal wind stress has been studied. The results show that meridional wind stress of one class that diverges or converges affects velocity and geopotency field. The disturbed termocline and the zonal flow of zero class are driven directly by wind stress and affected by Kelvin wave and short Rossby wave. Rossby wave is produced by meridional wind stress. The disturbed termocline and the zonal flow of second class are driven directly by wind stress and affected by short Rossby wave. At the same time, meridional wind stress also produces short Rossby wave. In addition, warm water is recruited to the equator district strongly at the west boundary, which indicates that meridional wind stress may have warm water conveyed to the equator. West wind stress has warm water at the west boundary conveyed easterly. |
