7. Wind Speed and Direction Wind speed and wind direction are plotted using a wind arrow.
The wind direction is plotted with the wind arrow indicating the direction of the wind blowing into the station circle.
8. Wind Speed Wind Speed is indicated by the number of half barbs, whole barbs, and flags.
The wind speed is indicated by the sum of the wind speeds represent by the half barbs, whole barbs and flags.
