Windpower "farms" do extensive wind rose type studies prior to erecting their wind turbines. If wind rose data had been collected and used prior to the construction of San Francisco's famous windy Candlestick Park, the stadium could have been placed a few hundred yards to the north where it would have been protected from the prevailing westerly wind. Step 1: Select a suitable scale (in this case 1 cm 10) Step 2: Draw a circle to represent the calm for this scale. Architects do, or should, use wind rose information for the siting of buildings and stadiums. Draw a wind rose diagram for the following data. 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. We often see it in the Business Magazines, Newspapers and Journal of Finance. Its a form of the Pie Chart now known as the Polar Area Diagram. 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. Nightingale Rose Diagram is the most famous statistical diagram. 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.
