ABSTRACT
The results from a hybrid approach that combines the forecasts of a mesoscale model with a diagnostic wind model to produce high-resolution wind forecasts in complex coastal orography are evaluated. The simple diagnostic wind model [Winds on Critical Streamline Surfaces (WOCSS)
] was driven with forecasts (on a 9-km grid) from the Coupled Ocean-Atmosphere Mesoscale Prediction System (COAMPS) to obtain detailed near-surface wind forecasts with 3-km horizontal spacing. Forecasts were produced by this hybrid model for four cold-season cases-two frontal and two nonfrontal-over the central California coastal region. They were compared with 3-km forecasts from the innermost COAMPS full ...
