Abstract
In this model, the QL-EWFB instability causes tropical convection to organize on the planetary scale and a wavenumber one Kelvin wave-like structure dominates the east-west circulation in the tropics. An increase of the static stability that is in phase with the surface evaporation stabilizes the EWFB mode. For large surface humidity, a hierarchy of convective structures appear as a result of the nonlinear adjustment of the QL mode at large amplitudes. Isolated grid-size individual convective zones move randomly, while a wavenumber one envelope of this convection propagates eastward at a constant speed. -from Authors
