A rose is a rose is a rose, except this rose! The featured image is a wind rose plot for the Des Moines airport for dates between 11 and 21 January. The plot is a wind climatology detailing frequency of wind direction and speed. The individual colors represent frequencies of observed wind speeds for 16 directions. The plot shows that winds from the Northeast and Southwest are rarely observed. The strongest wind speeds (20+ knots in red) are almost always from the Northwest, which is the most common wind direction. The plots of extremely valuable for designers who worry about wind transport of things like odor and particulates.
