Envelope Solitary Rossby Waves and Their Interactions under the Influence of Forcing and Dissipation
强迫耗散作用下的Rossby包络孤立波及其相互作用

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.
