Abstract
A finite element model is presented in order to solve a set of equations which describe the behaviour of moist, deep convection. The method employs elements spanning both time and space, and a variable time step and mesh size can be used. The equation for the pressure is solved in precisely the same manner as that used for the other dependent variables. An artificial, one-dimensional boundary layer flow, in which a mixed layer capped by an inversion is stabilized by cooling at the ground, is solved. The solution is found not to depend significantly upon the time step or the mesh size.
