earlier work on this problem. In particular, a spherical wave-mean flow model was developed and utilized to examine a forced planetary wave mechanism for the polar warming. A sizeable set of numerical experiments have now been performed with this model. The results show that a . Baroclinic instability in the atmosphere is well resolved by modern general circulation models (GCMs) and to predict the atmosphere with anything less than a full-fledged numerical model, with equations close to the full Navier–Stokes equations, would be by:   Large-scale baroclinic eddies shape the general circulation of Earth’s atmosphere. They are generated in midlatitudes through baroclinic instability, propagate meridionally, and dissipate near their critical lines on the flanks of the jet streams (Randel and Held ).Meridionally propagating eddies transport (angular) momentum toward their generation region (Held , ).Cited by: A Global Baroclinic Model with Point Vortices D.

The model regions at high resolution are kept at a minimum and can be individually tailored towards the research problem associated with atmospheric model simulations. The climate system is characterized by complex nonlinear interactions over a broad range of temporal and spatial scales. This parameterization, and its implementation in a numerical model of the middle atmosphere, are discussed in this paper. It is shown that including parameterized wave breaking leads to more realistic simulations of the dynamical and chemical structure of the stratosphere than are possible with conventional two-dimensional : R. R. Garcia. The book introduces the fundamentals of geophysical fluid dynamics, including rotation and stratification, vorticity and potential vorticity, and scaling and approximations. It discusses baroclinic and barotropic instabilities, wave-mean flow interactions and turbulence, and the general circulation of .

For a climate model to have a reasonable response to tropical forcing and teleconnection patterns, the model should have a realistic representation of (1) distribution of the tropical diabatic heating; (2) climatological mean flow, and thus small systematic errors, for Rossby wave propagation and wave-mean flow interactions; and (3 Author: Hai Lin, Jorgen Frederiksen, David M.
