What is Beaufort Scale?

A measurement determined by the wave lengths and sea conditions caused by the effect of wind, and by the movement of tree branches and chimney smoke on land, expressed with numbers from 0 to 12, used in wind connection and wind power extension by looking only at the results without referring to any device.
