Home > GFS Ensemble Wave 0.25 Degree Documentation

The Global Wave Ensemble System (GWES) is now unified with the Global Ensemble Forecast System (GEFS). The WAVEWATCH III wave model is one-way coupled with the atmospheric forecast model. This allows for an increase in frequency of the wind forcing from 3 hours to 1 hour. This unified system has 30 members and the wave model is initialized with the previous member's 6 hour forecast. The wave model has a spatial resolution of 0.25 x 0.25 degrees. The system runs four cycles per day (00, 06, 12 and 18Z). The wave forecast has been extended from 10 to 16 days.
