The longest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the strongest winds shown by deep blue.

There are not enough recording stations world wide to use actual wind data. Without question some coastal places have very localized wind effects that would not be predicted by NWW3. According to the model, the most common wind at Pleherel blows from the WNW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Pleherel.
