Abstract:

A perturbation of relative humidity is used as a trigger to start the convection process in a numerical model of a cumulus cloud. The effects of varying the width and depth of the perturbation are studied. It is found that the width of the simulated cloud is dependent on the width of the impulse, whereas the ultimate depth and rate of growth are dependent mainly on the depth of the impulse. If a suitable impulse is used, a simulated cloud results that has many of the properties of real clouds observed in an atmosphere with the same basic sounding as the computation.
