Wind roses are graphical charts that characterize the speed and direction of winds measured at weather stations. If the purple area along the spoke starts at a smaller ring (10 percent according to the label) and ends at a larger ring (24 percent according to the label), then subtract 10 from 24, as that tells you what percentage of time the wind blew at that speed and direction, 14 percent. For instance, it may tell you what percentage of time the winds are calm without you having to calculate it. For instance, if the color is purple, indicating on your particular map that it blew from the north at 15 to 25 miles (24 to 40 km) per hour, see where the color begins and ends along the rings within the spoke.
