Abstract: otivated by the temporal behavior of recent high-end tornado events, a 30-yr historical record of tornadoes in the United States is examined for multiple-day periods of tornado activity. Comprising the 3129 tornado days ...

Abstract: n the United States, tornado activity of a given year is usually assessed in terms of the total number of human-reported tornadoes. Such assessments fail to account for the seldom-acknowledged fact that an active (or ...

Abstract: This two-part study proposes a fundamental explanation of the genesis, structure, and implications of low-level, meso-?-scale vortices within quasi-linear convective systems (QLCSs) such as squall lines and bow echoes. ...

Abstract: The purpose of the Intermountain Precipitation Experiment (IPEX) is to improve understanding of precipitating systems in the Intermountain West. Instrumentation deployed during the field phase of IPEX sampled a strong cold ...

Abstract: This two-part study proposes fundamental explanations of the genesis, structure, and implications of low-level meso-?-scale vortices within quasi-linear convective systems (QLCSs) such as squall lines and bow echoes. Such ...

Abstract: he adiabatic and diabatic processes inherent to midlatitude deep convective storms are well known to modify the atmospheric temperature, moisture, and winds especially within horizontal scales equivalent to a Rossby radius ...

Abstract: This study examines the structure and evolution of quasi-linear convective systems (QLCSs) within complex mesoscale environments. Convective outflows and other mesoscale features appear to affect the rotational characteristics ...
