Distant Effects of a Recurving Tropical Cyclone on Rainfall in a Midlatitude Convective System: A High-Impact Predecessor Rain Event*
Abstract Recent research has identified predecessor rain events (PREs), which are mesoscale regions of heavy rainfall that occur ∼1000 km poleward and downshear of recurving tropical cyclones (TCs).Expand

The Vertical Structure of Mesoscale Convective Vortices
Abstract Simulations of two cases of developing mesoscale convective vortices (MCVs) are examined to determine the dynamics governing the origin and vertical structure of these features. Although oneExpand

A Global Climatology of Baroclinically Influenced Tropical Cyclogenesis
AbstractTropical cyclogenesis is generally considered to occur in regions devoid of baroclinic structures; however, an appreciable number of tropical cyclones (TCs) form in baroclinic environmentsExpand
