Abstract

The AA. have calculated the evolution of the spectral energetics of two cases of blocking from the winter of 1978-79. The first case occurred over the North Atlantic and the other over the North Pacific. The Atlantic block was forced by the nonlinear interaction of intense baroclinic cyclone-scale waves with barotropic, ultralong waves. The Pacific blocking resulted from the baroclinic amplificated of planetary-scale waves. In each case the blocking developed downstream of intense intermediate-or large-scale cyclogenesis. (JPB).
