RISWhat Should Be Considered When Simulating Doppler Velocities Measured by Ground-Based Weather Radars?
Publisher: American Meteorological Society
Abstract: A sophisticated and flexible simulator of Doppler velocities measured by ground-based weather radars is appended to a high-resolution nonhydrostatic atmospheric model. Sensitivity experiments are conducted by using different ...
Simulation of an Observed Squall Line with a Meso-Beta-Scale Hydrostatic Model
Publisher: American Meteorological Society
Abstract: This paper reports on simulations of an observed squall line with the meso-beta-scale hydrostatic PERIDOT model. An attempt is made to answer the question of what model changes are necessary to roughly simulate a squall ...
A Numerical Study of a Nontornadic Supercell over France
Publisher: American Meteorological Society
Abstract: A case of a nontornadic supercell over France is simulated with a three-dimensional nonhydrostatic cloud model. The simulation starts from an operational data analysis without any superimposed perturbation. The initial ...
Cloud-Resolving Ensemble Simulations of Mediterranean Heavy Precipitating Events: Uncertainty on Initial Conditions and Lateral Boundary Conditions
Publisher: American Meteorological Society
Abstract: This study assesses the impact of uncertainty on convective-scale initial conditions (ICs) and the uncertainty on lateral boundary conditions (LBCs) in cloud-resolving simulations with the Application of Research to ...
A Climatology of the Mesoscale Environment Associated with Heavily Precipitating Events over a Northwestern Mediterranean Area
Publisher: American Meteorological Society
Abstract: climatological approach is developed to characterize the mesoscale environment in which heavily precipitating events (HPEs) grow over a mountainous Mediterranean area. This climatology that is based on three-dimensional ...
Storm-Scale Numerical Rainfall Prediction for Five Precipitating Events over France: On the Importance of the Initial Humidity Field
Publisher: American Meteorological Society
Abstract: This paper presents results of numerical experiments on five precipitating events: two cases of convective systems over the northern French plains that induced localized flooding, two cases of quasi-stationary systems over ...
Coupling the ISBA Land Surface Model and the TOPMODEL Hydrological Model for Mediterranean Flash-Flood Forecasting: Description, Calibration, and Validation
Publisher: American Meteorological Society
Abstract: Innovative coupling between the soil?vegetation?atmosphere transfer (SVAT) model Interactions between Soil, Biosphere, and Atmosphere (ISBA) and the hydrological model TOPMODEL has been specifically designed for flash-flood ...
A Radar Simulator for High-Resolution Nonhydrostatic Models
Publisher: American Meteorological Society
Abstract: A full radar simulator for high-resolution (1?5 km) nonhydrostatic models has been developed within the research nonhydrostatic mesoscale atmospheric (Meso-NH) model. This simulator is made up of building blocks, each of ...
The Catastrophic Flash-Flood Event of 8–9 September 2002 in the Gard Region, France: A First Case Study for the Cévennes–Vivarais Mediterranean Hydrometeorological Observatory
Publisher: American Meteorological Society
Abstract: The Cévennes?Vivarais Mediterranean Hydrometeorological Observatory (OHM-CV) is a research initiative aimed at improving the understanding and modeling of the Mediterranean intense rain events that frequently result in ...
HyMeX-SOP1: The Field Campaign Dedicated to Heavy Precipitation and Flash Flooding in the Northwestern Mediterranean
Publisher: American Meteorological Society
Abstract: erranean region is frequently affected by heavy precipitation events associated with flash floods, landslides, and mudslides that cause hundreds of millions of euros in damages per year and, often, casualties. A major field ...
