Abstract: In this study, the structure of convectively generated rear-inflow jets and their role in the evolution of long-lived mesoconvective systems are investigated through an analysis of idealized three-dimensional simulations ...

Abstract: A series of idealized simulations using a nonhydrostatic cloud model is used to investigate the genesis of bow echoes (a bow-shaped system of convective cells that is especially noted for producing long swaths of damaging ...

Abstract: Bow echoes represent one of the unique and more well?known forms of severe convective organization, often being responsible for the production of long swaths of damaging surface winds and small tornadoes. They are identified ...

Abstract: A series of idealized simulations of supercell storms are presented for environments representing straight through circular hodographs to clarify the character of the storm dynamics over the large spectrum of hodograph ...

Abstract: Previous studies have revealed that convective storms often contain intense small-scale downdrafts, termed ?downbursts,? that are a significant hazard to aviation. These downbursts sometimes possess strong rotation about ...

Abstract: Long-lived, mesoscale convective systems are known to occasionally produce mesoscale convective vortices (MCVs) in the lower to middle troposphere with horizontal scales averaging 100?200 km. The formation of MCVs is ...

Abstract: Numerical simulations of the convective storms that form in tornado-producing landfalling hurricanes show that shallow supercells are possible, even though buoyancy is limited because ambient lapse rates are close to moist ...

Abstract: Supercells in the southern plains are often localized, forming as cells along a convective line, even though the environment may support supercell formation over a much broader, mesoscale region. A set of numerical experiments ...

Abstract: Convective storm simulations are conducted using varying thermal and wind profile shapes, subject to the constraints of strict conservation of convective available potential energy (CAPE) and hodograph trace. Small and ...
