Short summary

This study evaluates how well the High-Resolution Rapid Refresh (HRRR) model represents wind and cloud patterns off coastal California near Morro Bay and Humboldt. Comparisons with buoy and satellite data show that the model captures overall cloudiness but underestimates cloud top height and misses daily variations. HRRR performs well under cloudy skies but shows larger errors under clear conditions.
