Architects do, or should, use wind rose information for the siting of buildings and stadiums. Naval Oceanographic Office to get average winds for each ocean for each month of the year to help the create optimal sailing routes between ports. Sailors use wind rose information taken from the "Pilot Charts" by the U.S. The information provided by the wind rose can be applied to many and varied situations. A good example of a wind rose application is shown at the following URL. Wind speed data can be superimposed on each direction segment to indicate, for example, the average wind speed when the wind was blowing from that segment's direction and the maximum wind speed during the logging period. Typically the wind direction data is sorted into twelve equal arc segments, 30° each segment, in preparation for plotting a circular graph in which the radius of each of the twelve segments represents the percentage of time that the wind blew from each of the twelve 30° direction segments. The collected wind data is then sorted by wind direction so that the percentage of time that the wind was blowing from each direction can be determined.
To create a wind rose, average wind direction and wind speed values are logged at a site, at short intervals, over a period of time, e.g. The wind rose is the time honored method of graphically presenting the wind conditions, direction and speed, over a period of time at a specific location.
