Have you ever wondered what forecast model is the most accurate? With PredictWind’s Validation Tool you have the ability to see which model is currently doing the best job for your Forecast Location.

The Validation Tool compares each model's predictions relative to a real-time wind observation near your Forecast Location.

We can view the Validation Data in 2 formats, tables or graphs.

  • From the main menu, Click on Validation.

  • Video of how to use Validation tool.

  • This tutorial covers the Table format.

  • 1 Day, means we are seeing the average error for Day 1 of the past week’s or past month’s forecasts. We have the wind speed table and the wind direction table for each period.

  • In this example, we can see the PWG model has been doing the best job at predicting the windspeed and direction for Day 1 of the last week’s forecasts.

  • Further down the page on the map we can see the observation location that the comparison data is sourced from.

  • When we click on 7 Day, we get the average error for all 7 days of the forecasts. Again we have the average error for the past week’s or past month’s forecasts for each of the 7 days in the tables. It is interesting to see the change in the models performance as the days from forecast run increase, this gives a good insight in the models strengths and weaknesses for this location at this time.

  • In this example we can see the ECMWF performs well especially in days 4-7 compared to the other models.
