The process of geostrophic adjustment of localized large-scale pressure anomalies in the standard adiabatic shallow-water model on the equatorial beta-plane is revisited, and it is shown that the standard scenario of generation of westward-moving Rossby and eastward-moving Kelvin waves, which underlies the classical Gill theory of tropical circulation due to a localized heating, is not unique. Depending on the strength and aspect ratio of the initial perturbation, the response to the initial…

Can geostrophic adjustment of baroclinic disturbances in tropical atmosphere 1 explain MJO events? 2

Using the two-layer moist-convective rotating shallow water model, we study the process of relaxation (adjustment) of localized large-scale pressure anomalies in the lower equatorial troposphere, and

Eastward-moving equatorial modons in moist-convective shallow-water models

It is shown that steady large-scale slowly eastward-moving twin-cyclone coherent structures, the equatorial modons, exist in both one- and two layer versions of the rotating shallow water model on

Atmospheric dynamics in the equatorial region significantly differs from that in higher latitudes due to the simple fact that the rotation axis of the Earth lies in the tangent plane to the equator.

Geostrophic adjustment on the f-plane: Symmetric versus anti-symmetric initial height distributions

We study the fundamental process of geostrophic adjustment in infinitely long zonal and meridional channels of widths Ly and Lx, respectively, by deriving analytic solutions and simulating the

Turbulence and equatorial waves in moist and dry shallow water systems

Turbulence and large-scale waves in the tropical region are studied using the spherical shallow water equations. With mesoscale vorticity forcing, both moist and dry systems show kinetic energy

The response of a spherical moist shallow‐water system to tropical imbalances in the presence of inhomogeneous saturation fields is examined. While the initial moist response is similar to the dry

Turbulence and equatorial waves in moist and dry shallow‐water flow, excited through mesoscale stochastic forcing

Turbulence and large‐scale waves in the tropical region are studied using the spherical shallow‐water equations. With mesoscale vorticity forcing, both moist and dry systems show an upscale transfer

Observed wavenumber-frequency spectrum of global, normal mode function decomposed, fields: a possible evidence for nonlinear effects on the wave dynamics

Abstract. The study of tropical tropospheric disturbances has led to important challenges from both observational and theoretical points of view. In particular, the observed wavenumber-frequency
