Wind direction rose diagram (wind rose diagram for short) is also called wind direction frequency rose diagram. It is drawn according to a certain proportion according to the percentage value of each wind direction averaged in a certain area for many years. Generally, it is represented by eight or 16 compass bearing, so it is named after it looks like a rose.
The wind direction indicated on the rose diagram refers to the direction blowing from the outside of the area to the center. Line segments drawn in each direction according to statistical values indicate the wind frequency in that direction. The longer the line segment, the more times the wind direction appears.
Draw the line segment representing the wind frequency in all directions into line segments with different colors according to the numerical percentage of wind speed, that is, represent the average wind speed in all directions. This statistical chart is called the rose chart of wind frequency and speed.
