...In order to emphasise the importance of this phenomenon, let us recall that our understanding of the circulation patterns in the tropical atmosphere is largely based on the classical paper of Gill (1980), where the RSWmodel on the equatorial β-plane was used to study the effects of large-scale heating by adding a source to the mass conservation equation (1b)....

...(Gill 1980), the buoyancy, that is, the potential temperature in the atmospheric context, acts mainly as a catalyzer of pressure evolution not much changing itself in the absence of diabatic effects in the TRSWmodel....

...In our simulations, we have used the threestage third-order strong stability preserving (SSP) Runge-Kutta method (see, e.g. Gottlieb et al. 2011, 2001) with the time steps restricted using the following CFL condition with the CFL number 1/2: t = 1 2 min { x axmax , y aymax } , where axmax := maxj,k…...
