Abstract
We present a new parameterization of gravity wave drag based on the Medvedev and Klaassen [1995] theory of gravity wave spectral evolution and saturation. The scheme has been tested in a column model as well as with a mechanistic version of three-dimensional Middle Atmosphere CCM2 model. For the range of anticipated variability of source spectra in the troposphere the scheme produces plausible results consistent with observations and with theoretical estimates. Results also indicate that the specification of seasonal and latitudinal variability of wave sources is required for three-dimensional modeling.
