Output from ECWAM

ECWAM is run as:

• HRES WAM twice daily giving forecasts to Day10 associated with HRES forecasts based on 00UTC, 06UTC, 12UTC and 18UTC data times.  Global coverage 0.25^o x 0.25^o latitude-longitude grid (Ocean wave model ensemble 15-day forecast (Set IV ENS-WAM

...

• ).
• ENS-WAM twice daily giving forecasts to Day15 associated

• with ensemble forecasts  based on 00UTC and 12UTC data times.  Global coverage 0.25^o x 0.25^o latitude-longitude grid (Ocean wave model ensemble 15-day forecast (Set IV ENS-WAM).
• Extended ENS-WAM daily giving extended range forecasts from Day16 to Day46 associated with the extended range forecasts based on 00UTC data times.  Global coverage 0.5^o x 0.5^o latitude-longitude grid (Atmospheric Model Ensemble extended forecast (Set VI - ENS extended), section VI-v-c).

• WAM monthly for forecasts to 7 months ahead associated with the seasonal forecast model (System 5).  Global coverage 1.0^o x 1.0^o latitude-longitude grid (Atmospheric model Seasonal 7-month forecast (Set V - SEAS), section V-v-e).

• WAM quarterly for forecasts to 1 year ahead associated with the seasonal forecast model (System 5).  Global coverage 1.0^o x 1.0^o latitude-longitude grid (Atmospheric model Seasonal 7-month forecast (Set V - SEAS), section V-v-e).

       Output is in the form of wave and swell height, direction and period.  Also available are wave energy flux, mean direction and magnitude (important for assessment of the impact of the waves on coastlines and offshore structures).
