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 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.
Exceptionally high waves (small and medium-sized ships might be for time lost to view behind the waves). The sea is completely covered with long white patches of foam lying along the direction of the wind. Everywhere, the edges of the wave crests are blown into froth. Visibility greatly affected.
Sep 24, 2024 · 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 .
Beaufort wind force scale. The Beaufort scale, which is used in Met Office marine forecasts, is an empirical measure for describing wind intensity based on observed sea conditions.
Beaufort Wind Chart – Estimating Winds Speeds. Calm. Smoke rises vertically. Wind motion visible in smoke. Wind felt on exposed skin. Leaves rustle. Leaves and smaller twigs in constant motion. Dust and loose paper is raised. Small branches begin to move.
7. 28-33. Near Gale. Sea heaps up, waves 13-19 ft, white foam streaks off breakers. Whole trees moving, resistance felt walking against wind. 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.
How to read the Beaufort scale chart? If you have exact data about wind speed, you can connect it with the Beaufort scale number using the following chart, where you see Beaufort number from 0 to 12 and wind description in the beginning, then — water and land conditions.
A guide that helps mariners to estimate the wind speed over open water based on the observed wave conditions.
