Abstract. Tornadoes, with measured wind speeds of m s −1 to perhaps m s −1, are the most violent of atmospheric storms (Fig. ).A tornado is defined here as a violently rotating, narrow column of air, averaging about m in diameter, that extends to the ground from the interior of a cumulonimbus (or occasionally a cumulus congestus) cloud and appears as a condensation funnel Cited by: Supercell thunderstorms, and the tornadoes they spawn, are considered. Consistency with the current research trends within the disciplines of meteorology and geophysics is neglected in the pursuit of a mechanistic model that can more accurately describe the distinctive characteristics of tornadic supercells. Tornadic thunderstorms are the most intense and most damaging type of convective storm. Whereas ordinary convective cells grow, produce rain, and then decay over a period of 40 min to an hour. Estimating Disoersion from a Tornado Vortex and Meskyclone ' (U) vortex and transports them spiraling upward within the tornadic thunderstorms produce a rotating vortex and accompanying violent winds that flatten substantial natural and man-made kilicforklift.com: A.H. Weber, C.H. Hunter.

A more complete representation of the 3D wind field surrounding a tornado can be made with radar data using dual-Doppler syntheses.
