Dalhart Wind Rose

A wind rose is a diagram that depicts the distribution of wind direction and speed at a location over a period of time. The length of each bar represents the percent of time the wind blows from that direction. Each bar is subdivided with colors to show wind speed ranges associated with each direction.
