Pressure distributions on a cube in a simulated thunderstorm downburst, Part B: Moving Downburst Observations

The wind characteristics in thunderstorms, particularly downbursts, differ significantly from those of synoptic scale boundary layer winds. This paper describes work aimed at simulating the flow structure in a moving downburst and obtaining the transient pressure field on a cube immersed in such a flow. In Part A, data were presented for a stationary wall jet simulation of a downburst. This part presents the data from a moving downburst simulation and makes comparisons with the stationary wall jet simulation based on quasi-steady approaches. © 2002 Elsevier Science Ltd.
