14. Summary Southern LA –September: performance was very good for all three variables –October: daytime wind speed and temperatures were slightly under predicted  Could lead to excessive stagnation and higher ozone Northern LA –Performance was slightly but consistently worse –Daytime wind speeds and temperatures were also under estimated Overall –Wind were markedly better than usually achieved in other WRF applications across the country –Temperature performance was on par with other applications –Precipitation performance was quite good  Did not exhibit the usually high degree of over prediction 14
