Abstract: In this paper we present results of a model study of the Walker Circulation defined as the steady response of a stratified atmosphere to an isolated equatorial heat source. The model equations are linearized with respect ...

Abstract: A simple two-dimensional model is used to demonstrate the importance of the vertical distribution of latent heat release for the functioning of CISK, When the horizontal scale of the prescribed heat source in the model is ...

Abstract: The low-level circulation in summer over the western Indian Ocean is characterized by southeast trades that are channeled near the African coast into a concentrated southerly flow across the equator and thence north-eastward ...

Abstract: This analysis treats the transient inertia-gravity wave response of a shallow fluid to an impulsive addition of momentum. The Coriolis parameter varies with latitude, but Rossby waves are not considered. The square of the ...

Abstract: The vertical motion field in the thermosphere is calculated from the continuity equation. This calculation is based on a field of horizontal winds and an intermediate model of the thermospheric temperature field consistent ...

Abstract: The response of a stably stratified atmosphere to differential heating across a coastline is studied. A linear, inviscid, Boussinesq theory is used to analyze the growth caused by switching on a small temperature contrast ...

Abstract: This paper treats the initial value problem of a forced Rossby wave encountering a critical level in a barotropic zonal shear flow which can change in response to the wave momentum flux divergence. The main result of the ...

Abstract: A 5-day zonal wavenumber 1 oscillation has been well-documented from analysis of surface pressure data, and it has been suggested that it corresponds to the gravest symmetric low-frequency external normal mode of the ...
