45. Windrose

http://www.nc-climate.ncsu.edu/windrose.php
Windrose is a tool that meteorologist use to measure wind speed and direction distributed at a particular location. This is from and Airport in Raleigh, NC and the length of the vectors show the percentage of wind from that direction and wind speed is color coordinated to the legend. Looking at this you can observe which "spoke" is longest, and that is related to the frequency where wind blows the most often. This is useful for constructing airport runaways so aircraft can have the best advantage at take offs and landing.
