| Abstract: |
| The paper studies the short period response of an unbounded and uniform ocean to moving wind field.Firstly, it is shown that the response disturbance has two kinds of motion, one is geostrophical and other is inertial gravity wave.Secondly, this paper studies the disturbance source caused by a circular wind field which moves rapidly in a straight path on a horizontal plane.It is shown that the disturbance source is mainly determined by the distribution of the curl of wind stress.Thirdly, this paper studies the solution of disturbance equation with nonhomogeous term of disturbance source as an impulse.It is shown that the oceanic response is determined by disturbance source.Finally, by calculating numerically the current velocity and surface elevation in time, it is shown that the intensity, spatial scale and duration of the response are closely related to wind field. |
