摘　　要：使用多重尺度方法对斜压Rossby波在地形和δ效应共同作用下的不稳定性进行了研究,讨论了基本流和地形、δ效应对Rossby波结构的影响.结果表明,东西方向和南北方向地形对Rossby波的不稳定性和相速度以及能量传播有很大差异.Using multi-scale method,the instability of baroclinic Rossby waves under topography and δ effect were studied in the basic flow.The influences of the basic flows,topography and δ effect on the Rossby waves were examined.The results show that the instability and phase speed of the Rossby waves and energy transmission under the W-E oriented topography and the N-S oriented topography are quite different.

关 键 词：ROSSBY波 基本流 地形 不稳定性 δ效应
