RISUsing Gap-Filling Radars in Mountainous Regions to Complement a National Radar Network: Improvements in Multiple-Doppler Wind Syntheses
Publisher: American Meteorological Society
Abstract: he existing French Application Radar à la Météorologie Infrasynoptique (ARAMIS) operational radar network covers a vast majority of the country of France, yet like many national networks, gaps in coverage are present in ...
An Assessment of Low-Level Baroclinity and Vorticity within a Simulated Supercell
Publisher: American Meteorological Society
Abstract: dealized supercell modeling has provided a wealth of information regarding the evolution and dynamics within supercell thunderstorms. However, discrepancies in conceptual models exist, including uncertainty regarding the ...
Model Wind Field Forecast Verification Using Multiple-Doppler Syntheses from a National Radar Network
Publisher: American Meteorological Society
Abstract: odel verification has traditionally relied upon in situ observations, which typically exist on a sparse network, making nonsurface model forecast verification difficult. Given increasing model resolution, supplemental ...
High-Resolution Dual-Doppler Analyses of the 29 May 2001 Kress, Texas, Cyclic Supercell
Publisher: American Meteorological Society
Abstract: On 29 May 2001, Doppler on Wheels radars collected data on a supercell near Kress, Texas. The supercellular storm, cyclic in nature, produced multiple mesocyclones throughout its lifetime. Dual-Doppler syntheses were ...
In-Place Estimation of Wet Radome Attenuation at X Band
Publisher: American Meteorological Society
Abstract: he effect of wet radome attenuation is estimated on a French operational X-band weather radar deployed in the Maritime Alps of southeastern France. As the radar is deployed in a remote location, the reflectivity factor in ...

Stochastically Perturbed Parameterizations in an HRRR-Based Ensemble
Publisher: American Meteorological Society
Abstract: A stochastically perturbed parameterization (SPP) approach that spatially and temporally perturbs parameters and variables in the Mellor?Yamada?Nakanishi?Niino planetary boundary layer scheme (PBL) and introduces initialization ...
A Performance Comparison between Multiphysics and Stochastic Approaches within a North American RAP Ensemble
Publisher: American Meteorological Society
Abstract: stochastic parameter perturbation (SPP) scheme consisting of spatially and temporally varying perturbations of uncertain parameters in the Grell?Freitas convective scheme and the Mellor?Yamada?Nakanishi?Niino planetary ...
