A diagram designed to show the distribution of wind direction experienced at a given
location over a considerable period of time. Usually shown in polar coordinates (distance
from the origin being proportional to the probability
of the wind direction being at the given angle
usually measured from the north). Similar diagrams are sometimes used to summarize
the average concentrations of a given pollutant seen over a considerable period of
time as a function of direction from a given site (sometimes called a pollution rose).
