【摘要】 采用忽略Ｒｅｙｌｅｉｇｈ摩擦和Ｎｅｗｔｏｎ冷却的定常、线性大气模式和地转动量近似下的非线性海洋模式。这里包含了大气通过线性风应力影响海洋，海洋通过加热过程影响大气的物理机制。用相平面理论讨论了海气耦合作用对简单耦合线性Ｒｏｓｓｂｙ波和非线性Ｒｏｓｓｂｙ波的影响。结果指出，强海气作用易使西传的简单耦合Ｒｏｓｓｂｙ波不稳定，弱海气作用易使东传的Ｒｏｓｓｂｙ波不稳定。同时，讨论了海气作用对简单耦合Ｒｏｓｓｂｙ孤立波强度和宽度的影响更多还原

【Abstract】 A staionary, linear atmospheric model neglecting Reyleigh friction and Newtonian cooling is used in conjunction with a nonlinear ocean model with semi geostrophic approximation.(The ocean is affected by the atmosphere by linear wind stress and the atmosphere is influenced by the heating of SST) The effects of coupled ocean atmosphere interaction(represented as R) on the linear and nonlinear coupled Rossby waves are discussed with travelling wave method. The results show that strong( weak) ocean atmosphere interaction instablizes the west( east) propagating isolated Rossby waves. Additionally, the influence of the ocean atmosphere interaction on the intensity and width of Rossby soliton is also discussed.更多还原
