RISHigh-Resolution Simulations of Lee Waves and Downslope Winds over the Sierra Nevada during T-REX IOP 6
Publisher: American Meteorological Society
Abstract: he downslope windstorm during intensive observation period (IOP) 6 was the most severe that was detected during the Terrain-Induced Rotor Experiment (T-REX) in Owens Valley in the Sierra Nevada of California. Cross sections ...
A Physically Based Algorithm for Downscaling Temperature in Complex Terrain
Publisher: American Meteorological Society
Abstract: AbstractRecent improvements to an algorithm to be used operationally for downscaling screen temperatures from numerical weather prediction models are described. Testing against very high resolution dynamically downscaled ...
Parameterized Gravity Wave Momentum Fluxes from Sources Related to Convection and Large-Scale Precipitation Processes in a Global Atmosphere Model
Publisher: American Meteorological Society
Abstract: nalysis of a high-resolution, convection-permitting simulation of the tropical Indian Ocean has revealed empirical relationships between precipitation and gravity wave vertical momentum flux on grid scales typical of earth ...
Mountain Wave–Induced Polar Stratospheric Cloud Forecasts for Aircraft Science Flights during SOLVE/THESEO 2000
Publisher: American Meteorological Society
Abstract: The results of a multimodel forecasting effort to predict mountain wave?induced polar stratospheric clouds (PSCs) for airborne science during the third Stratospheric Aerosol and Gas Experiment (SAGE III) Ozone Loss and ...
The Terrain-Induced Rotor Experiment
Publisher: American Meteorological Society
Abstract: The Terrain-Induced Rotor Experiment (T-REX) is a coordinated international project, composed of an observational field campaign and a research program, focused on the investigation of atmospheric rotors and closely related ...
Intercomparison of Mesoscale Model Simulations of the Daytime Valley Wind System
Publisher: American Meteorological Society
Abstract: hree-dimensional simulations of the daytime thermally induced valley wind system for an idealized valley?plain configuration, obtained from nine nonhydrostatic mesoscale models, are compared with special emphasis on the ...
An Intercomparison of T-REX Mountain-Wave Simulations and Implications for Mesoscale Predictability
Publisher: American Meteorological Society
Abstract: umerical simulations of flow over steep terrain using 11 different nonhydrostatic numerical models are compared and analyzed. A basic benchmark and five other test cases are simulated in a two-dimensional framework using ...
The Community Foehn Classification Experiment
Publisher: American Meteorological Society
Abstract: AbstractStrong winds crossing elevated terrain and descending to its lee occur over mountainous areas worldwide. Winds fulfilling these two criteria are called foehn in this paper although different names exist depending ...
A Pan-African Convection-Permitting Regional Climate Simulation with the Met Office Unified Model: CP4-Africa
Publisher: American Meteorological Society
Abstract: AbstractA convection-permitting multiyear regional climate simulation using the Met Office Unified Model has been run for the first time on an Africa-wide domain. The model has been run as part of the Future Climate for ...
