Abstract

Some kinematic and dynamic structures of a microburst-producing storm in Colorado were investigated. Dual-Doppler data collected on 14 July, 1982 at 1647 MDT, during the Joint Airport Weather Studies (JAWS) project at Denver's Stapleton International Airport, were objectively analyzed to produce a three-dimensional wind field. The domain of interest had a horizontal dimension of 10 by 10 km centered on the microburst. Vertical velocities were computed by integrating the anelastic continuity equation downward from the storm's top with variational adjustment. Subsequently, fields of deviation perturbation pressure, density, and virtual temperature were retrieved from a detailed wind field using the three momentum equations.
