The coupling instability of Rossby and topographic Rossby waves in the equatorial area
In case of considering the fact that the tropical ocean thermocline or the lower atmosphere height field has the meridional variation, the topographic Rossby wave will be excited. Also the background geostrophic current emerges. Under such conditions, the topographic Rossby wave can interact with the classical Rossby wave at some parameter band and thus brings a new kind of instability, which may be of potential application in understanding some phenomena of the ENSO cycle.
