Bow Echo Mesovortices. Part I: Processes That Influence Their Damaging

WebThe objective is to relate the structure of mesovortices to the damaging winds produced by a bow echo. Ac-cordingly, analyses over a smaller region (21 km 21 km) were created in order to describe the kinematic structure near the apex of the bow echo. In particular, the life cycle of an intense mesovortex that developed at this location is shown. WebA review of early studies of these systems suggested that wind damage/speed was not continuous and instead was enhanced over many small areas. More recent research has revealed a close association between damaging winds, tornadoes, and low-level meso-γ-scale vortices (mesovortices) that develop within the convective portion of QLCSs.
