This same procedure can be followed for plotting air pollution concentration data if their average, or peak, values are known for each direction.

Click the Proceed button, and you will obtain the following plot. That means that within the given time period, the wind blew at speeds of 0 to 45 miles (72 km) per hour from that specific direction. A wind rose is a chart which gives a view of how wind speed and wind direction are distributed at a particular location over a specific period of time. centre circle - the bigger the circle, the higher is the frequency of calm When you access the page of the on line wind rose tool, some data are preloaded and, to save time, we are going to use such data in this example. The wind rose plotted with the on line tool does not have such feature, since all the frequencies are plotted starting from the centre of the plot, therefore it is more properly a radar plot. Each branch of the We will change the text of the Labels, which will be used for the legend, inserting for example 0-1 in place of Class 1, then 1-2, 2-3, 3-4 and >4 in place of Class 5. For instance, if the color is purple, indicating on your particular map that it blew from the north at 15 to 25 miles (24 to 40 km) per hour, see where the color begins and ends along the rings within the spoke. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws.
