DESCRIPTION:Convection is an essential process for transporting heat and m
 oisture in planetary atmospheres. The standard Earth picture of moist conv
 ection rising from the surface is only one of a number of modes of convect
 ion. Notably\, convection in atmospheres with a high condensible mass frac
 tion (non-dilute atmospheres)\, or with a lighter background gas than the 
 condensible species (e.g. water convection in a hydrogen dominated atmosph
 ere) - acts very differently and can be much weaker or even shut down enti
 rely in the latter case. Here I present a new mass-flux scheme which can c
 apture these variations and simulate convection in a wide range of paramet
 er space for use in 3D climate models. A validation using the case of Trap
 pist-1 e is presented.
