The Development and Maintenance of Rotation in Convective Stormsrms and their close association with severe weather. Although not all severe thunderstorms rotate, an operational evaluation study conducted at NOAA’s National Severe Storms Laboratory showed that most of the storms containing meso-cyclones identifiable by doppler radar produced either tornadoes or

Cumulus Rotation: Model and Observations of a Waterspout-bearing Cloud Systemfor destructive tornadic vortices have been made using Doppler radar observations. A typical tornado-associated “mesocyclone” has a diameter of 5–10 km, tangential wind velocities 15–25 ms. and vorticities in the neighs borhood of 10. s.. Only about 60 percent of these strong meso-cyclones produce f

Observational and Theoretical Aspects of Tornadogenesisamics has been reviewed recently by DAVIES-JONES (1981). In theoretical work it is generally assumed that the tornado is a vertical vortex, but it is often inclined appreciably. The direction and degree of tilt offers insights, hitherto unexplored into the character of the velocity field in which th

High Resolution Numerical Simulations of the Tornadic Region Within a Mature Thunderstorm storm enters its tornadic phase. This structure is characterized by a downdraft outflow which wraps around the center of storm circulation at low levels and an associated distortion from a single cell to a two-cell up-draft structure (Brandes, 1978; Lemon and Doswell, 1979). In this study we invest
