Abstract: Nearly 50 years of observations of hook echoes and their associated rear-flank downdrafts (RFDs) are reviewed. Relevant theoretical and numerical simulation results also are discussed. For over 20 years, the hook echo and ...

Abstract: Two long-lived tornadic supercells were sampled by an automobile-borne observing system on 3 May 1999. The ?mobile mesonet? observed relatively warm and moist air, weak baroclinity, and small pressure excess at the surface ...

Abstract: climatology of tornadoes in Turkey is presented using records from a wide variety of sources (e.g., the Turkish State Meteorological Service, European Severe Weather Database, newspaper archives, Internet searches, etc.). ...

Abstract: dealized, dry simulations are used to investigate the roles of environmental vertical wind shear and baroclinic vorticity generation in the development of near-surface vortices in supercell-like ?pseudostorms.? A cyclonically ...

Abstract: n idealized numerical simulations of supercell-like ?pseudostorms? generated by a heat source and sink in a vertically sheared environment, a tornado-like vortex develops if air possessing large circulation about a vertical ...

Abstract: umerical simulations are used to investigate how the attenuation of solar radiation by the intervening cumulonimbus cloud, particularly its large anvil, affects the structure, intensity, and evolution of quasi-linear ...
