#45 Wind Rose

>Soure: http://mensch.org/vplot/windrose2/windrose.png
A wind rose is helpful to meteorologists because it graphically shows both where the wind is coming from and its frequency of the speed. The length of the vectors on the wind rose graph show the percentage of time the wind blew from a particular direction. On this particular chart one can tell that the winds came in from a westerly direction.
