Dynamical Model Simulation of the Morning Boundary Layer Development in Deep Mountain Valleys
Publisher: American Meteorological Society
Abstract: A dry, two-dimensional version of the Colorado State University Multi-dimensional Cloud/Mesoscale Model was used to study the cross-valley evolution of the wind and temperature structures in an idealized east-west oriented ...
Effects of Shear, Stability and Valley Characteristics on the Destruction of Temperature Inversions
Publisher: American Meteorological Society
Abstract: A dry two-dimensional version of the Colorado State Cloud/Mesoscale Model was used to study the morning, inversion destruction cycle in a variety of deep mountain valley configurations. Eleven simulations were run to examine ...
Numerical Simulation of Cross-Valley Plume Dispersion during the Morning Transition Period
Publisher: American Meteorological Society
Abstract: A two-dimensional dynamical model was used to simulate the daytime boundary-layer evolution and resulting plume dispersion in a cross-valley section of a northwest?southeast oriented narrow valley in the first 4 h after ...
Mesoscale Boundary-Layer Evolution over Complex Terrain. Part II: Factors Controlling Nocturnal Boundary-Layer Structure
Publisher: American Meteorological Society
Abstract: The development of the nocturnal boundary layer (NBL) over a sloping plateau upwind of a high mountain barrier is studied with a numerical model and field observations. Six numerical simulations and one observed case are ...
Mesoscale Boundary Layer Evolution over Complex Terrain. Part I. Numerical Simulation of the Diurnal Cycle
Publisher: American Meteorological Society
Abstract: The continuous development of a meso-?-scale boundary layer over sloping terrain upwind of a high mountain barrier was simulated through a complete diurnal cycle using a nonhydrostatic boundary-layer model. The simulation ...
Preliminary Study of California Wintertime Model Wet Bias
Publisher: American Meteorological Society
Abstract: The Weather Research and Forecasting (WRF) model version 3.0.1 is used in both short-range (days) and long-range (years) simulations to explore the California wintertime model wet bias. California is divided into four ...
