Windroses are maps in a circular format, this windrose shows the frequency of winds blowing from certain directions and the the frequency of time the wind blows from a particular direction. Each circle represents a different frequency, other information such as directions (North, South, East, West) can also be shown since the windrose map originated from the compass.
This shows a wind rose of data from Spring time, March-April. A wind rose is a diagram that depicts wind direction and speed distribution at a location over a period of time. The length of the spoke indicates how often the wind comes from that direction, longer spokes mean the wind comes from the direction more often while shorter indicates less frequency. The dotted ring labels indicate the percentage while the colors display how often the wind speed falls within a given range of speed.
