Wind Rose Information. The station identification, month, and period of record (1984-1992) are located at the top left of each wind rose. The percent frequency of calm winds is located in the lower left side of the wind rose plot. The frequency of occurrence of winds is plotted in the sixteen points of the compass (north, north-northeast, northeast, etc.) with a maximum of six wind speed classes for each direction. The legend for the wind speed colors is at the bottom left of each wind rose. Wind Rose Uses Wind roses can be used to graphically depict the predominant transport direction of an area's winds.
