000022673 520__ $$2eng$$aLarge Eddy Simulations (LES) using an idealized cooling source (CS) downburst model have been used to investigate the important geometric and thermal parameters that govern a thunderstorm downburst outflow. These simulations use a modified version of Bryan Cloud Model, version 1 (CM1), a meteorological cloud model for atmospheric phenomena. A significant variation in thermodynamic cooling exists in a thunderstorm cloud and this paper presents an assessment of some aspects of that variation. Certain quantities, such as the cooling source shape, size, aspect ratio, height above datum and peak cooling source intensity are modified. An existing scaling procedure has been adopted for a non-dimensional analysis of wind-related metrics, with some success.
