There are not enough recording stations world wide to use actual wind data. No doubt some coastal places have very localized wind effects that would not be predicted by NWW3. According to the model, the dominant wind at Dumbea Rights blows from the S. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Dumbea Rights. Converseley, dominant spokes show favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from.
