BEAUFORT SCALE, a series of numbers from o to 12 arranged by Admiral Sir Francis Beaufort (1774-1857) in 1806, to indicate the strength of the wind from a calm, force o, to a hurricane, force 12, "that which no canvas could withstand." The British Admiralty accepted the scale for the open sea in 1838 and it was adopted in 1874 by the International Meteorolog ical Committee for international use in weather telegraphy. The Beaufort scale as originally drawn up made no reference to the velocity of the wind and various attempts, particularly during the present century, have been made to correlate the two. One such correlation, determined in 1906 by the Meteorological Office is shown below. The Deutsche Seewarte table differs appreciably from this, particularly in the higher part of the scale. An at tempt to systematize the scales led to a request to Dr. Simpson in 1921 for a definite scale. His conclusions published in 1926 suggest inter alia that there is no unique relationship between wind velocity as recorded by anemometers and estimates made on the Beaufort scale.
