Windrose

A windrose is a meteorological diagram depicting the distribution of wind direction and speed at a location over a period of time. Presented in a circular format, the wind rose shows the frequency of winds blowing from particular directions. The length of each "spoke" around the circle is related to the frequency that the wind blows from a particular direction per unit time. This particular windrose is of the city of Seattle.
