Abstract
Abstract Some dynamic and thermodynamic structures of a microburst-producing storm, which occurred on 14 July 1982 in Colorado, were studied in detail during the storm's quasi-steady mature stage. Dual-Doppler data from 1646 to 1648 MDT, collected during the project of Joint Airport Weather Studies (JAWS) 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 km by 10 km centered on the microburst. There were 19 analysis levels in the vertical, ranging from 0.25 to 8.5 km AGL. The horizontal grid spacing was 0.5 km, while thevertical grid spacing varied from 0.25 km near the surface to 0.5 km at levels above I kin. 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 and virtual temperature were recovered from a detailed wind field using the three mo...
