TL;DR: In this article, the structure of stationary Rossby waves in the presence of a mean westerly zonal flow with vertical shear is examined and the vertical structure, horizontal wavenumber and group velocity of the external mode, and the projection onto this mode of topographic and thermal forcing are studied with continuous models (a linear shear profile as well as more realistic basic states), and a finite-differenced model with resolution and upper boundary condition similar to that used in GCMs.

TL;DR: In this paper, an improved energy budget-based parameterization for the mesoscale eddy diffusivity was proposed, and a series of numerical simulations were performed, using an idealized flat-bottomed β-plane channel configuration with quadratic bottom drag.

TL;DR: In this paper, a barotropic model was designed to study the interaction of the Hadley cell with a Rossby wave forced in midlatitudes by a stationary “topographic” source, and the response of the mean zonal and meridional winds to infinitesimal wave forcing was analyzed in detail.

TL;DR: Mearns et al. as discussed by the authors proposed a method to estimate the probability of a tropical cyclone at the National Center for Atmospheric Research (NCAR) in the United States.

TL;DR: In this paper, the amplitude of the linear, stationary response to low-level extratropical heating decreases as the magnitude of the low level mean flow increases, while amplitude of orographically forced waves increases.
