EVALUATION OF SEARCHING AND RESCUE (SAR) METHOD FOR DETERMINING LOCAL WIND CURRENT; INTERIM REPT. FEB-JUL 91

This report discusses a preliminary investigation of the National Search and Rescue (SAR) Manual method for calculating wind driven currents. The SAR Manual recommends a manual method developed by Mooney (1 978). The derivation of the model is reviewed and the local wind current predictions are compared with the Mellor Yamada Level 2 1/2 model (Mellor-Yamada, 1982), a complex one-dimensional model of the mixed layer. Several aspects of the model are assessed for physical correctness. Recommendations for a manual and a numerical method are provided based on the comparison of the predications of the SAR-Mooney model with those of the Mellor-Yamada Level 2 1/2 model. Consequently, these recommendations should be regarded as provisional until the experimental investigation has been performed and the results analyzed. search and rescue (SAR), wind driven currents, Ekman Current.
