Beaufort scale

n.
A scale of wind force ranging from 0 (calm) to 12 (hurricane), corresponding with the velocity of wind at a set distance above ground or sea level.

[After Sir Francis Beaufort (1774-1857), British naval officer.]

Beaufort scale

n
(Physical Geography) meteorol an international scale of wind velocities ranging for practical purposes from 0 (calm) to 12 (hurricane force). In the US an extension of the scale, from 13 to 17 for winds over 64 knots, is used
[C19: after Sir Francis Beaufort (1774–1857), British admiral and hydrographer who devised it]

Beau′fort scale′

(ˈboʊ fərt)
n.
a scale for indicating the force or speed of wind, using numbers from 0 to 12 or sometimes 17.
[1855–60; after Sir Francis Beaufort (1774–1857)]

Beau·fort scale

(bō′fərt)
A scale for classifying the force of the wind, ranging from 0 (calm) to 12 (hurricane). The scale was devised in 1805 as a means of describing the effect of different wind velocities on ships at sea.

Beaufort scale

(wind scale) A scale that rates the force of wind from 0 to 12, a rating of 0 being absolute calm and one of 12 being hurricane force.
