PredictWind Forecasts More Accurate
Than Ever
PredictWind has made significant improvements to their weather
models. 10 years of development has culminated in the release of the most
accurate iteration of the PWG & PWE forecast model to date. This
means that the PredictWind models now give you more forecast confidence than
ever before, making your time on the water safer and more enjoyable.
To
validate the improvement, we undertook an intensive verification study using
real time data from 77 weather stations around the globe. For each station 1
month of one hour interval readings were compared to the forecasts based on
the new PredictWind model versus the existing model. The results of the study
show on average a 12% improvement using the new PredictWind model for wind
speed, and a 7% improvement in Wind Direction. |
