Wind rose

A wind rose is a picture that shows which directions the wind usually blows from and how strong it usually is. It looks a bit like a wheel with the middle being a circle and the points of the wheel being the directions the wind can blow from (like North, South, East, and West). The strength of the wind is shown by the length of the lines from the center of the wheel to the points. Longer lines mean the wind is usually stronger in that direction.
