The Beaufort scale (/ ˈboʊfərt / BOH-fərt) is an empirical measure that relates wind speed to observed conditions at sea or on land. Its full name is the Beaufort wind force scale. History. Sir Francis Beaufort.
Beaufort Wind Scale. One of the first scales to estimate wind speeds and the effects was created by Britain's Admiral Sir Francis Beaufort (1774-1857). He developed the scale in 1805 to help sailors estimate the winds via visual observations. The scale starts with 0 and goes to a force of 12.
Moderately high (18-25 ft) waves of greater length, edges of crests begin to break into spindrift, foam blown in streaks. Twigs breaking off trees, generally impedes progress. 9. 41-47. Strong Gale. High waves (23-32 ft), sea begins to roll, dense streaks of foam, spray may reduce visibility.
The Beaufort Scale is an empirical measure that relates wind speed to observed conditions at sea or on land. Its full name is the Beaufort wind force scale. Below is a table showing the Beaufort Scale with speeds in knots, miles per hour and kilometres per hour.
Beaufort scale, scale devised in 1805 by Commander (later Admiral and Knight Commander of the Bath) Francis Beaufort of the British navy for observing and classifying wind force at sea. Originally based on the effect of the wind on a full-rigged man-of-war, in 1838 it became mandatory for log entries in all ships in the Royal Navy.
The Beaufort scale, which is used in Met Office marine forecasts, is an empirical measure for describing wind intensity based on observed sea conditions.
Wind felt strongly on face. Smoke rises at about 30 deg. Slack halyards whip while bending continuously to leeward. Taut halyards maintain slightly bent position.
The Beaufort scale, officially known as the Beaufort wind force scale, is a descriptive table. It depicts the force of wind by a series of numbers, typically from 0 to 12. The Beaufort scale goes all the way to 17, but the last five numbers only apply to tropical typhoons.
The Beaufort Wind Force Scale, devised in the early 19th century by British naval officer Sir Francis Beaufort, remains a crucial tool for sailors and meteorologists alike. This scale quantifies wind intensity based on observed sea conditions, offering a standardized measure of wind strength.
In the summer of 1805, Beaufort was appointed to the command of the Woolwich, a 44-gun man-of-war. In 1806, he wrote in his log book a wind force scale. The scale was simple and very similar to one that Alexander Dalrymple had written in a book in 1789.
