Description
Summary:The synchronous response of tropical ocean to meridional and zonal wind stress has been studied. The results show that meridional wind stress of the first order that diverges or converges affects the velocity and geopotential fields. The disturbed termocline and the zonal flow of the zeroth order 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 the second order mode are driven directly by wind stress and affected by short Rossby wave. At the same time, the meridional wind stress also produces the short Rossby wave. In addition, warm water is recruited to equator district strongly at the west boundary, which indicates that the meridional wind stress may transport the warm water equatorward, and the westerly wind stress transports the warm water at the west boundary eastward.
