A ship in a force 12 ("hurricane-force") storm at sea, the highest rated on the Beaufort scale. The Beaufort scale (/ ˈ b oʊ f ər t / 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.

The most common way of describing wind force is with the Beaufort scale [3] that 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.

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.

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

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.

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 .

The Beaufort scale, which is used in Met Office marine forecasts, is an empirical measure for describing wind intensity based on observed sea conditions. These values refer to well-developed...

Gale force winds are an incredible phenomenon in the world today, and they are a perfect example of our earth’s weather systems. They are winds that travel between 31 mph (50 km/h) and 63 mph (102 km/h) as a strong and persistent gust over a continued period of time.

Sea surface like a mirror, but not necessarily flat. Smoke rises vertically. Ripples with the appearance of scales are formed, but without foam crests. Direction of wind shown by smoke drift, but not wind vanes. Small wavelets, still short but more pronounced. Crests do not break. When visibility good, horizon line always very clear.

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 …
