Abstract
Two parameterization schemes for cloud and precipitation formation, by Kessler and Sundqvist respectively, are described, and compared while simulating various atmospheric conditions. To do this, a simple one-dimensional numerical model is used. The effect of changes in parameter values in the two schemes are studied, and it is shown that Sundqvist's and Kessler's schemes, when used on the same cases and with a suitable choice of parameters, give results with good correspondence with each other. Results from the calculations are also compared with available measurements. The results demonstrate that the simpler Sundqvist scheme is suitable for implementation in a numerical weather prediction model.
