耗散和强迫作用下的时间周期地转运动

Time-Periodic Quasigeostrophic Motion under Dissipation and Forcing

Jinqiao Duan

摘要:

准地转方程是一个典型的地球物理流体模型。在本文中,我们考虑的时间周期运动的耗散和时间相关的风强迫下,该模型。在$β$参数、Ekman数、粘性和区域大小满足一定条件的情况下,证明了当风强迫具有时间周期性且风强迫的空间平方积分在时间上有界时,完全非线性准地转模式具有时间周期运动.

英文摘要:

The quasigeostrophic equation is a prototypical geophysical fluid model. In this paper, we consider time-periodic motions of this model under dissipation and time-dependent wind forcing. We show that when the wind forcing is time-periodic and the spatial square-integral of the wind forcing is bounded in time, the full nonlinear quasigeostrophic model has time-periodic motions, under some conditions on $β$ parameter, Ekman number, viscousity and the domain size.
