Abstract: A theory is presented for the spectra of horizontal velocity and temperature at high wavenumbers in three-dimensional quasi-geostrophic flow. The theory predicts a minus third power dependence on both the horizontal and ...

Abstract: Why do cyclones form in a conditionally unstable tropical atmosphere whose vertical thermal structure is apparently more favorable to small-scale cumulus convection than to convective circulations of tropical cyclone scale? ...

Abstract: The properties of wind-driven equatorial currents in homogeneous oceans are investigated for variable wind stresses and variable eddy viscosities. In the case of a uniform westward stress, the calculated cross-stream and ...

Abstract: A two-layer baroclinic model is used to study the planetary-scale motions of a thermally driven atmosphere in the presence of topography, and in doing so to extend previous results obtained with a barotropic model. Highly ...

Abstract: A barotropic channel model is used to study the planetary-scale motions of an atmosphere whose zonal flow is externally driven. Perturbations are induced by topography and by d barotropic analogue of thermal driving. The ...

Abstract: Results f rum a series of numerical simulations are presented to show the effects of changes in albedo on rainfall in six areas, two each in Africa, Asia and North America. Each pair consists of a semi?arid area lying at ...
