Wind Direction Standard Deviation (10 m)
The standard deviation of the wind direction.
  • This variable is a measure of the steadiness of wind direction. A small standard deviation indicates the wind is blowing from the same direction; a large standard deviation indicates significant changes in wind direction during the 5-minute interval. The standard deviation may be large for either inclement weather or relatively light winds.
