The Beaufort scale is a handy device for estimating wind speed. It was devised in 1805 by a British Admiral, Sir Francis Beaufort (1774-1857). Beaufort's intention was to create a standard method of assessing wind speed, based on sailors' descriptions of the wind's effect on the water. In 1926 the scale was modified so it could also be used on land.
