Windrose

A windrose is a tool used by meteorologist to show wind speed and direction at a location over a given period of time. The windrose is fundamentally based off of the compass rose in order to give a precise reading on the wind direction. Meteorologist use these for tracking wind currents and can also be helpful in the prediction of tornados. The wind rose below uses lighter colors to represent light winds and darker colors to represent heavy wind in its location.
