Windrose

http://www.maine.gov/dep/air/meteorology/Windrosehome.html
A windrose is a circular plot showing the frequency of different wind directions. This windrose, produced from a tracking site in Maine, covers a five year period of data. Since wind direction and speed are affected by topography and other geographic factors, windroses are generally site-specific graphs.
