DISSIPATIVE DESTABILIZATION OF EXTERNAL ROSSBY WAVES.
Journal of the Atmospheric Sciences 43:4 (1986) 388-396
Abstract:
External Rossby waves in vertical shear can be destabilized by thermal damping. They can also be destabilized by damping of potential vorticity if this damping is larger in the lower than in the upper troposphere. Results are described in detail for Charney's model. Implications for the effects of diabatic heating and mixing due to smaller scale transients on equivalent barotropic stationary or quasi-stationary long waves are discussed. It is pointed out that energy or potential enstrophy budgets may indicate that transients are damping the long waves while, in fact, their presence is destabilizing these waves.The Effect of Local Baroclinic Instability on Zonal Inhomogeneities of Vorticity and Temperature
