Abstract
A simplified model was constructed to describe the emission of barotropic Rossby waves by a moving baroclinic vortex. Estimates of energy expenditures for the emission of barotropic waves and baroclinic Rossby waves of different size and intensity were used to derive an expression to evaluate vortex lifetimes. The theoretical estimates of vortex lifetimes made taking into account the emission of barotropic Rossby waves were shown to be close to their observed values.
