Abstract:

Prediction of wind flow in a complex coastal environment is a challenging task that continues to be of interest to the U.S. Navy, specifically for use in the Tactical Environmental Support System TESS. TESS is a computer workstation which provides environmental information for the Navys tactical decision makers and is discussed in detail in Phegley and Crosiar 1991. According to Mass and Dempsey 1986, global and regional models have improved to the point where the adequately predict larger scale synoptic conditions however, conversion of these forecasts into local and mesoscale weather is still a problem. One solution is to increase the resolution of a global or regional model to that desired for mesoscale prediction. The problem with this is that computational requirements for the model would far exceed the capability of TESS. Another solution is to run simple mesoscale models which use observations or output from the more complex models for initialization. Until recently, computational requirements of simple mesoscale models were beyond the capabilities of TESS. However, the TESS hardware has been upgraded to a system which is now capable of running simple mesoscale models.
