Use of extended range forecasts in ship routing

Surface wave action has been proven to be the biggest deterrent to a ship's progress through the water. Until the present time forecasts of surface waves have been available for only a few days. In order to determine an optimum ship route across the ocean these wave forecasts must be extended to 15-20 days. Using three computer programs from the Fleet Numerical Weather Facility and the U.S. Weather Bureau 5-day and 30-day forecasts of the mean sea level pressures as input data, surface wave forecasts may be prepared for periods up to 30 days. When compared with the actual waves over the specified period of time, the forecast wave patterns show more skill than forecast waves derived strictly from climatology.
