Using a nondivergent barometric model simulation, the role of the meridional basic flow in generating the tropical-extra-tropical teleconnection was studied. It was found that a southernly basic flow will transfer Rossby wave sources downstream through advection so that a forcing embedded in the deep tropical easterlies may excite a Rossby wave response in the extratropical westerlies. This observation indicates that geographically fixed teleconnection patterns may be explained by simple Rossby wave theories.
