  • Description:
    "During the period OOGCT 22 February 1988 through OOGCT 6 March 1988, the Nested Grid Model (NGM) was run in a parallel mode, for both 00 and 12 GCT runs, in addition to the operational runs. The parallel mode used the same analyses as the operational mode, but its forecast model included a simple parameterization of mountain wave drag. (The expression "mountain wave drag" is used to denote the effect of gravity waves that are generated in the atmosphere by flow over uneven terrain.) In the model, gravity waves generated by the explicitly represented height field h can be assumed to be forecast by the model. Parameterization is needed however to account for gravity waves generated in response to unevenness of the terrain on horizontal scales shorter than that of h . Figure 1, for example, shows the standard deviation of the height field from a locally averaged height field, as computed from the 10' tabulation from the U. S. Navy"--Page 1, paragraph 1.
