Weakness and Strength

• IHigher resolution than the EFS

15 or 27 vs 75 km

Typically more skill than our EFS

Best at shorter forecast ranges

It is an ensemble member in and of itself

Has meteorological details

Put details often introduce errors!



• I EFS and global models are too course for features which can really impact

the local and regional weather Smooth out terrain features Smooth out finer scale features

Flooding and severe weather events are typically meso-b and meso-g features

Finer resolution models and Local Area Models play a valuable role in filling the gaps

Diagnosis of stability can help in many cases
