An anemometer is commonly used to measure wind speed. Global distribution of wind speed at 10m above ground averaged over the years 1981–2010 from the CHELSA-BIOCLIM+ data set [1] In meteorology, wind speed, or wind flow speed, is a fundamental atmospheric quantity caused by air moving from high to low pressure, usually due to changes in ...
Wind speeds over 99 knots are extracted by subtracting 50 from the direction and adding 100 to the speed. Thus, for example, the wind forecast for Abilene (ABI) at 30,000 feet, shown above as 7603, indicates a forecast wind of 260 degrees at 103 knots (76-50=26 or 260, and speed became 100+03=103).
Wind speed on the Beaufort scale is based on the empirical relationship: [6] v = 0.836 B 3/2 m/s; v = 1.625 B 3/2 knots (=) where v is the equivalent wind speed at 10 metres above the sea surface and B is Beaufort scale number.

Wind speeds over 75 miles per hour are classified as “hurricane force,” capable of pushing moving vehicles off the highway, overturning mobile homes and peeling off roofs. The average wind ...
The planes endured peak winds of around 265 mph, the second "strongest upper-level wind recorded in local history going back to the mid-20th century," the National Weather Service's Baltimore ...
The highest wind speed in Oregon, 73 miles per hour, was recorded at the Yaquina Bay Bridge in Newport. Corbett, Eugene, and Florence recorded peak gusts of 50, 52, and 67 miles per hour (80, 84, and 108 km/h), respectively. Winds of 45 miles per hour (72 km/h) were recorded at Portland International Airport. [29]
Compared to over water, maximum sustained winds over land average 8% lower. [12] More especially, over a city or rough terrain, the wind gradient effect could cause a reduction of 40% to 50% of the geostrophic wind speed aloft; while over open water or ice, the reduction is between 10% and 30%.
