Abstract: Influence functions (IFs) of a linear barotropic vorticity equation model are computed in order to determine the regions in which anomalous divergence at upper levels, related to tropical heating anomalies, has the largest ...

Abstract: The response of planetary waves to stationary tropical heating in a stratified global atmosphere linearized with respect to a basic zonal mean flow is investigated. The basic zonal wind has meridional and vertical shear. ...

Abstract: Resonant interactions among equatorial waves in the presence of a diurnally varying heat source are studied in the context of the diabatic version of the equatorial ?-plane primitive equations for a motionless, hydrostatic, ...

Abstract: We consider the problem of the linear response of a stratified, equatorial, ?-plane model atmosphere to specified transient sources of heat and momentum. The method of solution involves transforms in all three spatial ...

Abstract: The spectral cumulus parameterization theory of Arakawa and Schubert is presented in the convective flux form as opposed to the original detrainment form. This flux form is more convenient for use in numerical prediction ...

Abstract: One possible explanation for the relatively high signal of the mixed Rossby?gravity waves observed in the tropical atmosphere is explored in this paper. This explanation is based on the nonlinear interactions among equatorial ...

Abstract: AbstractIn the present study a simplified multiscale atmosphere?ocean coupled model for the tropical interactions among synoptic, intraseasonal, and interannual scales is developed. Two nonlinear equatorial ?-plane ...

Abstract: Weakly nonlinear interactions among equatorial waves have been explored in this paper using the adiabatic version of the equatorial ?-plane primitive equations in isobaric coordinates. Assuming rigid lid vertical boundary ...

Abstract: A linearized system of equations for the atmosphere's first internal mode in the vertical is derived. The system governs small-amplitude, forced, axisymmetric perturbations on a basic-state tangential flow which is independent ...

Abstract: Many frost events over southeastern Brazil are accompanied by a large-amplitude upper trough of the middle latitudes that extends well into the Tropics. This paper first illustrates that a mechanism of downstream amplification ...
