To show where the wind blow to (usefull for pollutant rose). If True, the windrose will be pi rotated, bins : 1D array or integer - number of bins, or a.If not set, nsectors=16, then each sector will beģ60/16=22.5°, and the resulting computed table will be aligned with the nsector : integer - number of sectors used to compute.var : 1D array - values of the variable to compute.direction : 1D array - directions the wind blows from, North centred.

Var bins and for each sector, a colored bar will be draw on the axes. Windrose.WindroseAxes instance Plot a windrose in bar mode. Windrose, calling help(ax.bar) will give :īar(self, direction, var, **kwargs) method of Parameters to control the windrose production. We’ve been excited to perform some wind climatology analyses ourselves, and we hope our users will find this new feature useful as well.In addition of all the standard pyplot parameters, you can pass special You can then right-click on the wind rose image, save it, and then repeat the process for another period for comparison (for instance, December 1st to March 1st for the years of 2002 to 2012). With this new feature, it’s easy to look at just the winter season for a range of years (for instance, December 1st to March 1st for the years of 1970 to 1980). This new functionality allows the wind rose to be used to study wind patterns during specific times of the year, and also analyze changes in wind patterns at a station.įor an example of how this new functionality could be used, image that you are interested in knowing if the winds near your location came from the north more frequently during winters in your childhood than they do now. This could be a specific day, week, month, season or any other period the user selects over a range of years. We have added the ability to plot a wind rose for a specific range of calendar days. We are excited to announce that an updated version of our wind rose tool is available! This web product now has new search capabilities that make it a more powerful climatological resource, along with a new look that we hope will make it easier to visually process. For example, the longest spoke on the wind rose represents the greatest frequency of winds blowing from that particular direction over the specified time frame. The wind rose is divided into a number of spokes which represent the frequency of winds blowing from a particular direction. A wind rose is a graphical tool used to show wind speed and wind direction for a particular location over a specified period of time.
