Wind Rose Maps



A Wind Rose map is a map of a given locality or area, showing the frequency and strength of the wind from various directions. It is a meteorological diagram depicting the distribution of wind direction and speed at a location over a period of time. This map represents a wind rose map because it shows distribution of wind direction for the month of January over a 24 hour period. It shows the percentage of time the wind is blowing in a particular direction as shown by the rings in the figure. The colors show the percentage of time the wind speed is from that direction.
