Wind Rose

I found some code online to plot a wind rose. I used data from the my personal weather station to plot wind direction, frequency, and speed on this beautiful wind rose.


I participated in NASA's Student Airborne Research Program in 2013. I studied weather influences on air pollution in the Los Angeles area. As part of my project I made the following pollution rose plots. They are similar to the wind rose shown above, but these only show the wind direction at the daily maximum ozone concentration. Plotted is every day between April 1 and September 30 between 2008 and 2012. It is colored by the max ozone concentration for that day.

    1. It's a histogram on polar coordinates.
      I modified the code from here:

  3. What do the circles represent on the wind rose diagram, i.e the numbers 4.3, 8.5, 12.8?
