A ship in a force 12 (" hurricane -force") storm at sea, the highest rated on the Beaufort scale. The Beaufort scale / ˈboʊfərt / 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 .
The most common way of describing wind force is with the Beaufort scale which defines a gale as wind from 50 kilometres per hour (14 m/s) to 102 kilometres per hour (28 m/s). It is an empirical measure for describing wind speed based mainly on observed sea conditions.
May 22, 2024 · A gale force wind or gale is a strong, persistent wind ranging from 50 km/h or 31 mph to 102 km/h or 63 mph and is typically associated with but not limited to coastal regions. According to the Beaufort Scale, gale force winds can be broken down into four subcategories.
8. 34-40. Gale. 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 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.
Oct 19, 2023 · 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.
gale, wind that is stronger than a breeze; specifically a wind of 28–55 knots (50–102 km per hour) corresponding to force numbers 7 to 10 on the Beaufort scale. As issued by weather service forecasters, gale warnings occur when forecasted winds range from 34 to 47 knots (63 to 87 km per hour).
The Beaufort scale, which is used in Met Office marine forecasts, is an empirical measure for describing wind intensity based on observed sea conditions.
May 13, 2019 · The Beaufort scale is a method of estimating wind speed based on the general condition of the surface of a large body of water with respect to wind waves and swell. It is based on observation of sea state rather than accurate wind measurements.
