A Sensitivity Study of a One-Dimensional Time-Dependent Warm Cumulus Cloud Model.

Abstract

A one-dimensional time-dependent computer cloud model was initiated with a composite of two soundings from day 226 of the GATE project. The soundings were recorded on August 14, 1974 at 1200 Z, off the west coast of Africa from two ships, the DALLAS (USA) and VISE (USSR). The model simulates the life cycle of a cylindrical shaped warm cumulus cloud which is in hydrostatic equilibrium. Although it is formulated in one-dimension, it includes effects from the surrounding environment by turbulent and dynamic entrainment. A series of model runs were executed in which several parameters were varied in order to observe their effects on the evolution of the model cloud. These parameters were: cloud radius, heat pulse duration, cloud condensation nuclei, and model time step duration.
