An Accurate Spectral Non-Orographic Gravity Wave Drag Parameterization for General Circulation Models
An accurate method of solution is developed for the Warner and McIntyre parameterization of non-orographic gravity-wave drag for the case of hydrostatic dynamics in the absence of rotation. The new scheme is sufficiently fast that it is suitable for operational use in a general circulation model. Multi-year climate runs of the Canadian Middle Atmosphere Model are performed using the new scheme,...
متن کاملSelf-Acceleration in the Parameterization of Orographic Gravity Wave Drag
A new effect related to the evaluation of momentum deposition in conventional parameterizations of orographic gravity wave drag (GWD) is considered. The effect takes the form of an adjustment to the basicstate wind about which steady-state wave solutions are constructed. The adjustment is conservative and follows from wave–mean flow theory associated with wave transience at the leading edge of ...
متن کاملThe physics of orographic gravity wave drag
*Correspondence: Miguel A. C. Teixeira, Department of Meteorology, University of Reading, Earley Gate, PO Box 243, Reading RG6 6BB, UK e-mail: [email protected] The drag and momentum fluxes produced by gravity waves generated in flow over orography are reviewed, focusing on adiabatic conditions without phase transitions or radiation effects, and steady mean incoming flow. The orographi...
متن کاملThe Effect of Back-Reflection in the Parameterization of Non-Orographic Gravity-Wave Drag
An efficient method of solution is developed for the Warner and McIntyre parameterization of the drag associated with nonhydrostatic non-orographic inertia–gravity waves. The scheme is sufficiently fast as to enable, for the first time, fully interactive multi-year climate simulations that include the effects of rotation and nonhydrostatic wave dynamics in the parameterization of non-orographic...
متن کاملToward a Physically Based Gravity Wave Source Parameterization in a General Circulation Model
Middle atmospheric general circulation models (GCMs) must employ a parameterization for small-scale gravity waves (GWs). Such parameterizations typically make very simple assumptions about gravity wave sources, such as uniform distribution in space and time or an arbitrarily specified GW source function. The authors present a configuration of the Whole Atmosphere Community Climate Model (WACCM)...
