Side note: there's a python module called windrose that works really well. The development of a wind rose requires a large amount of data. There is plenty of examples online, including some Excel workbooks you can reuse, for example here or here. Understanding wind direction and magnitude impact on site planning. it seems very eeasy but when i put the directions (N,NE,E,etc) the visual doesnt sort by names (like 1.N, 2.NE, 3.E, etc) only sort by the values from greatest. The first thing is to use the aster plot visual. If you want to take wind speed into account, you'll need to bin, for each cardinal direction, the wind speed in increments as well, so that you end up with a table made with COUNTIFS (eg COUNTIFS(ColumnOfCardinalDirection, "NE", ColumnOfWindSpeed, ">1", ColumnOfWindSpeed, "<2") to get number of hours where the wind blows from the North East, and the wind speed is between 1 and 2 m/s). I want to create a wind rose direction in PowerBI, i read many sites in google/youtube but i dint find anything that it is usefull to me. When looking at a wind rose, you'll see it's constructed with spokes coming out from a center point that show the wind direction each of the spokes are.
You'll basically want to convert the angles to cardinal directions (see here for tips on how to do it), then do a COUNTIF (eg COUNTIF(ColumnOfCardinalDirection, "NE") to get the number of hours where the wind blows from the North East), either using a formula or a pivot table. A wind rose is a circular diagram used to record data about wind speeds and frequencies over a specified period of time, which is handy if you want to know the average wind speeds for an area. Open that in Excel, you'll get many variables including hourly Wind Speed (m/s) and Wind Direction (degrees).ĭefine what kind of wind rose you want to achieve: do you want to plot the only wind direction, or do you want to also take wind speed into account? I have a preference for the second one of course.Īssuming you just want to take the wind direction into account, you need to "bin" the number of occurrences of a given direction, excluding cases where wind speed is zero.
