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 ...
A Mesovortex within a Near-Equatorial Mesoscale Convective System during TOGA COARE
Publisher: American Meteorological Society
Abstract: Airborne Doppler radar observations are used to investigate the internal structure of a midlevel mesovortex that developed within the rear part of the stratiform precipitation region of a mature-to-decaying mesoscale ...
A Multiple-Doppler Synthesis and Continuity Adjustment Technique (MUSCAT) to Recover Wind Components from Doppler Radar Measurements
Publisher: American Meteorological Society
Abstract: A new approach is presented to account for a simultaneous solution of the three wind components from at least a pair of Doppler radar observations, which could remove potential drawbacks of an iterative (nonsimultaneous) ...
Airflow and Precipitation Fields within Deep Alpine Valleys Observed by Airborne Doppler Radar
Publisher: American Meteorological Society
Abstract: Although airborne Doppler radar is increasingly relied upon to provide detailed descriptions of mesoscale precipitation systems in remote and complex meteorological settings, the utility of these observations has often ...
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 ...
Operational Multiple-Doppler Wind Retrieval Inferred from Long-Range Radial Velocity Measurements
Publisher: American Meteorological Society
Abstract: The recent deployment of an innovative triple pulse rise time (PRT) scheme within the French operational radar network allows for the simultaneous collection of reflectivity and radial velocity measurements up to a range ...
Regionalizing Rainfall at Very High Resolution over La Réunion Island: A Case Study for Tropical Cyclone Ando
Publisher: American Meteorological Society
Abstract: nsemble simulations of Tropical Cyclone (TC) Ando (31 December 2000?9 January 2001) are performed over the southwest Indian Ocean using the nonhydrostatic WRF Model. Nested domains centered over the island of La Réunion ...
Unusually High Differential Attenuation at C Band: Results from a Two-Year Analysis of the French Trappes Polarimetric Radar Data
Publisher: American Meteorological Society
Abstract: The differential phase (ΦDP) measured by polarimetric radars is recognized to be a very good indicator of the path integrated by rain. Moreover, if a linear relationship is assumed between the specific differential phase ...
Evaluation of Precipitation from Numerical Weather Prediction Models and Satellites Using Values Retrieved from Radars
Publisher: American Meteorological Society
Abstract: Precipitation is evaluated from two weather prediction models and satellites, taking radar-retrieved values as a reference. The domain is over the central and eastern United States, with hourly accumulated precipitation ...
Development of a Nationwide, Low-Level Wind Shear Mosaic in France
Publisher: American Meteorological Society
Abstract: n algorithm for the detection of horizontal wind shear at low levels was developed. The algorithm makes use of data collected by all radars from the Application Radar à la Météorologie Infra-Synoptique (ARAMIS) operational ...
