Each wind force is recognized by its common effects on objects in the landscape (dust, flags, trees, etc.) and on people in the open, or on the state of the sea surface. The highest value on the Beaufort scale, force 12, describes all wind strengths exceeding 121 km/h as hurricanes, but this...

Corresponding wind speeds were added to the scale in 1926 and the scale was standardized in 1939 . In its modern form it relates wind force and speed to the wind’s visible effects. The scale is given in Appendix 3...
