RISSensitivity of a Mesoscale Model to Microphysical Parameterizations in the MAP SOP Events IOP2b and IOP8
Publisher: American Meteorological Society
Abstract: The sensitivity of a mesoscale model to different microphysical parameterizations is investigated for two events of precipitation in the Mediterranean region, that is, the Mesoscale Alpine Program (MAP) intensive observation ...
Structure of the Atmospheric Boundary Layer in the Vicinity of a Developing Upslope Flow System: A Numerical Model Study
Publisher: American Meteorological Society
Abstract: The development of a morning upslope flow is studied by means of idealized numerical simulations. In particular, two cases are examined: a plane slope connecting a lower plain and an elevated plateau and a symmetric mountain ...
Daytime Development of the Boundary Layer over a Plain and in a Valley under Fair Weather Conditions: A Comparison by Means of Idealized Numerical Simulations
Publisher: American Meteorological Society
Abstract: he daytime thermal structures of the valley boundary layer (VBL) and of the convective boundary layer (CBL) above a plain, as revealed by idealized large-eddy simulations, are compared. Simulations in the two environments ...
Daytime Heat Transfer Processes Related to Slope Flows and Turbulent Convection in an Idealized Mountain Valley
Publisher: American Meteorological Society
Abstract: The mechanisms governing the daytime development of thermally driven circulations along the transverse axis of idealized two-dimensional valleys are investigated by means of large-eddy simulations. In particular, the impact ...
Climatology of Westerly Wind Events in the Lee of the Sierra Nevada
Publisher: American Meteorological Society
Abstract: 5-yr climatology of westerly wind events in Owens Valley, California, is derived from data measured by a mesoscale network of 16 automatic weather stations. Thermally driven up- and down-valley flows are found to account ...
Atmospheric Rotors and Severe Turbulence in a Long Deep Valley
Publisher: American Meteorological Society
Abstract: he conceptual model of an atmospheric rotor is reexamined in the context of a valley, using data from the Terrain-Induced Rotor Experiment (T-REX) conducted in 2006 in the southern Sierra Nevada and Owens Valley, California. ...
Skill and potential economic value of forecasts of ice accretion on wind turbines
Publisher: American Meteorological Society
Abstract: This paper presents a verification study of the skill and potential economic value of forecasts of ice accretion on wind turbines. The phase of active ice formation has been associated with the strongest wind power production ...
Wave-Induced Boundary Layer Separation in the Lee of the Medicine Bow Mountains. Part I: Observations
Publisher: American Meteorological Society
Abstract: wo cases of mountain waves, rotors, and the associated turbulence in the lee of the Medicine Bow Mountains in southeastern Wyoming are investigated in a two-part study using aircraft observations and numerical simulations. ...
Wave-Induced Boundary Layer Separation in the Lee of the Medicine Bow Mountains. Part II: Numerical Modeling
Publisher: American Meteorological Society
Abstract: ountain waves and rotors in the lee of the Medicine Bow Mountains in southeastern Wyoming are investigated in a two-part paper. Part I by French et al. delivers a detailed observational account of two rotor events: one ...
