Severe Downslope Windstorm Calculations in Two and Three Spatial Dimensions Using Anelastic Interactive Grid Nesting: A Possible Mechanism for Gustiness

摘要: Abstract The Clark nonhydrostatic anelastic code is extended to allow for interactive grid nesting in both two and three spatial dimensions. Tests are presented which investigate the accuracy of different quadratic interpolation formulae used derive boundary conditions fine mesh model. Application conservation condition Kurihara others shown result significant improvements treatment nesting. A improvement solutions versus parasitic also context forced gravity wave flow. This result, system, agreement with earlier results Phillips Shukla, who considered hydrostatic shallow water system equations. model applied simulation severe downslope windstorm 11 January 1972 Boulder using three-dimensional a gustiness signature ...
