EQUILIBRIUM STATES OF PLANETARY WAVES FORCED BY TOPOGRAPHY AND PERTURBATION HEATING AND BLOCKING SITUATION


doi: 10.1007/BF02677252

  • By using a two-level, highly truncated spectral model,the equilibrium states of ultra-long waves induced by topographic and thermal forcing are obtained, and the instabilities of the states are studied. It is found that there exist some stable equilibrium states possessing typical characteristics of blocking situation. Some inferences about the dynamic mechanism of blocking phenomenon are deduced since the solutions are analytically obtained.

Abstract: By using a two-level, highly truncated spectral model,the equilibrium states of ultra-long waves induced by topographic and thermal forcing are obtained, and the instabilities of the states are studied. It is found that there exist some stable equilibrium states possessing typical characteristics of blocking situation. Some inferences about the dynamic mechanism of blocking phenomenon are deduced since the solutions are analytically obtained.
