Abstract: Dual-Doppler wind syntheses from mobile radar observations obtained during the International H2O Project document some of the spatial variability of vertical wind profiles in convective boundary layers. Much of the variability ...

Abstract: Numerical simulations of squall lines traversing sinusoidal mountain ridges are performed using the Advanced Regional Prediction System cloud-resolving model. Precipitation and updraft strength are enhanced through orographic ...

Abstract: Numerical simulations of supercell thunderstorms that include parameterized radiative transfer and surface fluxes are performed using the Advanced Regional Prediction System (ARPS) to investigate the effects of anvil shadows ...

Abstract: Vertical wind shear is commonly classified as ?directional? or ?speed? shear. In this note, these classifications are reviewed and their relevance discussed with respect to the dynamics of convective storms. In the absence ...

Abstract: A climatology of dryline frequency and location is presented based on 30 yr (1973?2002) of April, May, and June surface observations from the Great Plains region of the United States. Drylines having a horizontal specific ...

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: Overdetermined, dual-Doppler wind syntheses are used to document the evolution, structure, and dynamics of vertical vorticity extrema observed in a convective boundary layer during the 12 June 2002 International H2O Project ...
