强迫耗散作用下的Rossby包络孤立波及其相互作用

本文讨论了强迫和耗散对Rossby包络孤立波的影响，得到了在强迫和耗散共同作用下，当准共振条件和锁相条件满足时，包络孤立波从外场那里获取能量来克服耗散并形成稳定的锁相包络孤立波。本文还研究了在强迫和耗散作用下两个包络孤立波的碰撞相互作用，发现在某些参数下，两波碰撞后性质变化不大，而在另外一些参数下，碰撞后两波性质显著改变。

Envelope Solitary Rossby Waves and Their Interactions under the Influence of Forcing and Dissipation

In this paper the effects of forcing and dissipation on envelope solitary Rossby waves are studied, It is found that under the quasi-resonance condition and phase-locking conditions an envelope solitary wave gaines energy from the external forcing field to overcome the dissipation and becomes a steady phase-locking solitary wave. The effects of forcing and dissipation on the collision interaction of two enevlope solitary waves are also studied. The results show that for a range of parameters the collision are soliton-like in the sense that the properties of the two waves change very little. For other parameters, the properties of the two waves change a lot after the collision.
