Since the wind direction is in polar coordinates a basic average will not work. I.e., average values of 355° and 5°, you will result in 180° instead of 0°. Therefore, the wind direction should be averaged direction dependent.
Note: The wind direction is only averaged direction dependent when the name of the wave with the wind direction information is “wind_dir”. Wind speed is averaged direction dependent when the name of the wave with the wind velocity information is “wind_vel”. Moreover, the direction dependent averaging for the wind_velocity is not directly popped on the “sanity_plot” graph (this graph shows the normally averaged wind velocity), but the wave is generated and stored under the corresponding Time series folder with the name “wind_vel_degdep”.
