RISThe Influence of Topography and Ambient Stability on the Characteristics of Cold-Air Pools: A Numerical Investigation
Publisher: American Meteorological Society
Abstract: high-resolution numerical investigation of a cold-air pooling process (under quiescent conditions) is carried out that systematically highlights the relations between the characteristics of the cold-air pools (e.g., slope ...
An Evaluation of the MM5, RAMS, and Meso-Eta Models at Subkilometer Resolution Using VTMX Field Campaign Data in the Salt Lake Valley
Publisher: American Meteorological Society
Abstract: This study presents what is, to the authors' knowledge, the first intercomparison and evaluation of three state-of-the-art mesoscale numerical models, the fifth-generation Pennsylvania State University?NCAR Mesoscale Model ...
Strong Wind Speed Events over Antarctica and Its Surrounding Oceans
Publisher: American Meteorological Society
Abstract: AbstractStrong wind events (SWEs) over Antarctica and its surrounding oceans are investigated using gridded surface wind data from the ERA-Interim for the 1979?2017 period. Throughout the year, SWEs are more prevalent over ...
Downslope Flows on a Low-Angle Slope and Their Interactions with Valley Inversions. Part II: Numerical Modeling
Publisher: American Meteorological Society
Abstract: The characteristics of well-developed downslope winds observed by tethered balloon soundings at multiple locations over a low-angle slope in the Salt Lake Valley are studied using the Regional Atmospheric Modeling System ...
Downslope Flows on a Low-Angle Slope and Their Interactions with Valley Inversions. Part I: Observations
Publisher: American Meteorological Society
Abstract: Thermally driven downslope flows were investigated on a low-angle (1.6°) slope on the west side of the floor of Utah?s Salt Lake Valley below the Oquirrh Mountains using data from a line of four tethered balloons running ...
A Modeling Study of the Effects of Inhomogeneous Surface Fluxes on Boundary-Layer Properties
Publisher: American Meteorological Society
Abstract: A numerical modeling study was conducted to examine the response of the atmospheric boundary layer to inhomogeneous surface fluxes. The study was used to extend the results obtained from a field experiment carried out in ...
Sensitivity of MM5-Simulated Boundary Layer Characteristics to Turbulence Parameterizations
Publisher: American Meteorological Society
Abstract: The sensitivity of high-resolution mesoscale simulations to boundary layer turbulence parameterizations is investigated using the fifth-generation Pennsylvania State University?NCAR Mesoscale Model (MM5) and observations ...
An Observational Study of Sea- and Land-Breeze Circulation in an Area of Complex Coastal Heating
Publisher: American Meteorological Society
Abstract: The diurnal evolution of the three-dimensional structure of a mesoscale circulation system frequently occurring in the area of Kennedy Span Center-Cape Canaveral has been studied using the data from the Kennedy Space Center ...
The Effects of Large-Scale Winds on the Sea Land-Breeze Circulations in an Area of Complex Coastal Heating
Publisher: American Meteorological Society
Abstract: A three-dimensional mesoscale numerical model has been used to examine the effects of large-scale background winds on the characteristics of the sea?land-breeze circulations over an area with an irregular coastline and ...
The Dependence of QPF on the Choice of Boundary- and Surface-Layer Parameterization for a Lake-Effect Snowstorm
Publisher: American Meteorological Society
Abstract: ix forecasts of a lake-effect-snow event off Lake Erie were conducted using the Weather Research and Forecasting Model to determine how the quantitative precipitation forecast (QPF) was affected when the boundary- and ...
