RISNumerical Simulation of Organized Convection. Part I: Model Description and Preliminary Comparisons with Squall Line Observations
Publisher: American Meteorological Society
Abstract: A numerical model designed for the simulations of mesoscale flows perturbed by deep convective clouds is discussed. It is based on the time dependent coupling between a three-dimensional nonhydrostatic mesoscale model and ...
Small Time and Space Measurements of the Mean Rainfall Rate Made by a Gage Network and by a Dual-Polarization Radar
Publisher: American Meteorological Society
Abstract: Small time (1 to 15 min) and space (0.5 to 1. 5 km) measurements of the mean rainfall rate have been made within 10 km from a dual-polarization radar, during several widespread or convective precipitation events. At first, ...
Radar Differential Reflectivity ZDR: A Real-Case Evaluation of Errors Induced by Antenna Characteristics
Publisher: American Meteorological Society
Abstract: Multiple parameter radar measurements (dual frequency hail signal DFR-HS or differential reflectivity ZDR) can be strongly affected by the mismatch of the antenna illumination functions at the two wavelengths or polarizations. ...
Case Study and Climatological Analysis of Upper-Tropospheric Jet Stream and Stratosphere–Troposphere Exchanges Using VHF Profilers and Radionuclide Measurements in France
Publisher: American Meteorological Society
Abstract: AbstractThe authors present a climatological analysis of tropospheric horizontal wind profiles and jet stream events using long series of wind profiles from two VHF profilers located in France: Lannemezan (2001?14) and ...
