Monthly forecast weekly means are calculated for some atmospheric variables and stored in the stream ENFO (1035) for the real-time forecast and stream ENFH (1039) for he hindcasts with type FCMEAN. Monthly forecast weekly maximum (type FCMAX), minimum (type FCMIN) and standard deviation (type FCSTDEV) have also been calculated and archived for all surface fields.

 

Wave model forecast means (weekly means) are calculated and stored in the stream WAEF (1081) for the real-time forecast and stream ENWH (1084) for the hindcast.

 

 

Forecast step ranges are 96-264, 264-432, 432-600 and 600-768 hours.

 

Parameters available in dissemination for various data streams are listed in the tables bellow.
