The wind rose was developed
in order to show the frequency and strength of wind from various directions in
a given area. This particular wind
rose is showing the reading from the Timber Weather Station on December 6th
and 7th. On the map each ring represents the frequency in percentage
that the wind is coming from a certain direction. Here the largest cone reaches
to the ring that says 72% and is pointed in the West, this means that 72% of
the time, winds blew from the West. The smaller cone only reaches to 24% and pointed WSW
indicating that 24% of the time, the winds blew from the WSW. The frequency of
the wind is indicated by the color on the map there is a key included showing
that the highest color is orange which is greater than 25 mph wind speed. The lowest
color is a soft purple, which is just indicated as calm.
