Beaufort scale. 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 .

Learn how to measure wind force using the Beaufort Wind Scale, a system of numbers from 0 to 64 that correspond to different levels of wind speed and direction. The scale ranges from calm to hurricane, with 8 for gale and 64 for hurricane. See the appearance of wind effects on the water and on land, and the WMO classification of wind force.
Jun 19, 2023 · Gale force winds are strong, persistent winds ranging from 50 km/h to 102 km/h and are typically associated with coastal regions. They can be caused by a rapid drop in air pressure or a rapid increase in air temperature, and they can be dangerous and destructive. Learn more about the Beaufort Scale, the factors that influence gale force winds, and some examples of places where they occur.
A gale is a strong wind; the word is typically used as a descriptor in nautical contexts. The U.S. National Weather Service defines a gale as sustained surface winds moving at a speed of between 34 and 47 knots ( 63–87 km/h, 17.5–24.2 m/s or 39–54 miles/hour ). [1] Forecasters typically issue gale warnings when winds of this strength are ...
Learn how to estimate wind speeds and effects using the Beaufort scale, developed by Admiral Sir Francis Beaufort in 1805. See the descriptions and specifications for each force of wind, from calm to hurricane, at sea and on land.
These values refer to well-developed wind waves of the open sea. The lag effect between the wind getting up and the sea increasing should be borne in mind. To convert knots to mph multiply by 1.15, for m/s multiply by 0.514. The Beaufort scale, which is used in Met Office marine forecasts, is an empirical measure for describing wind intensity ...
Oct 19, 2023 · The Beaufort scale is a descriptive table that measures the force of wind by a series of numbers, from 0 to 12. A moderate gale is a wind speed of 50 to 61 kph (32 to 38 mph), and a whole gale is a wind speed of 89 to 102 kph (55 to 64 mph).
