The Diffraction of Kelvin Waves and Bores at Coastal Bends
Publisher: American Meteorological Society
Abstract: Bends in coastal mountain ranges may diffract propagating atmospheric Kelvin waves and trapped coastal currents. Analytic solutions exist for the diffraction of both linear Kelvin waves and linear nonrotating gravity waves. ...
A Theory for Strong, Long-Lived Squall Lines
Publisher: American Meteorological Society
Abstract: We study herein the mechanics of long-lived, line-oriented, precipitating cumulus convection (squall lines) using two- and three-dimensional numerical models of moist convection. These models, used in juxtaposition, enable ...

Structure and Evolution of Numerically Simulated Squall Lines
Publisher: American Meteorological Society
Abstract: Using a three-dimensional numerical cloud model, we investigate the effects of vertical wind shear on squall-line structure and evolution over a wide range of shear magnitudes, depths, and orientations relative to the line. ...

Effects of Coastal Orography on Landfalling Cold Fronts. Part II: Effects of Surface Friction
Publisher: American Meteorological Society
Abstract: The role of surface friction in modifying cold fronts as they make landfall in regions of steep coastal orography is examined by means of idealized simulations. Both the effects of the surface-roughness change at the coast ...
Models of Coastally Trapped Disturbances
Publisher: American Meteorological Society
Abstract: During the spring and summer, the climatological northerly flow along the U.S. west coast is occasionally interrupted by transitions to southerly flow that have a limited offshore scale and appear to be manifestations of ...
The Resolution Dependence of Explicitly Modeled Convective Systems
Publisher: American Meteorological Society
Abstract: The representation of convective processes within mesoscale models with horizontal grid sizes smaller than 20 km has become a major concern for the simulation of mesoscale weather systems. In this paper, the authors ...
