  • Beaufort Wind Scale - National Weather Service
    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 The Beaufort scale is still used today to estimate wind strengths
  • The Beaufort Wind Scale | Royal Meteorological Society
    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 Table - Canada. ca
    A guide that helps mariners to estimate the wind speed over open water based on the observed wave conditions
  • Beaufort wind force scale - Met Office
    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
  • Beauforts Wind Scale - The Engineering ToolBox
    The Beaufort wind scale is divided into series of values, from zero for calm winds, up to twelve and above for hurricanes Each value represents a specific range and a classification of wind velocity with an accompanying descriptions of the effects on surface features
  • What is the Beaufort scale? | The Weather Guys
    A Beaufort force 6 is a near gale with wind speeds between 25 and 30 mph and includes white foam from breaking waves that begins to be blown in streaks along the wind direction A Beaufort force in the range of 6 to 7 is designated as strong winds; 8 to 9 as gale-force winds; and 10 to 11 as storm-force winds
  • NOAAs National Weather Service - Glossary
    Beaufort Force 1 - Wind 1-3 kt, Light Air, Scaly ripples, no foam crests Smoke drift indicates wind direction, still wind vanes Beaufort Force 2 - Wind 4-6 kt, Light Breeze, Small wavelets, crests glassy, no breaking waves Wind felt on face, leaves rustle, vanes begin to move
  • Weather Lingo: The Beaufort Wind Force Scale
    In the US, when winds reach force 6 or higher, the NWS begins issuing advisories and warnings for different environments For marine areas, force 6-7 winds would prompt a small craft advisory, force 8-9 would warrant a gale wind warning, and a wind reaching force 10-11 would call for a storm warning
  • Beaufort Wind Speed Estimation Scale - Windows to the Universe
    The Beaufort Wind Scale is named after Sir Francis Beaufort, an admiral in the British Navy He developed the scale in 1805 in order to estimate wind speed by noting how sails move in the wind It turned out to be a great help and was later adapted for use on land Force 0 Strength: Calm
  • Force 6 - Openwaterpedia
    noun - Force 6 or Force Six is a measure of wind speed based mainly on observed sea conditions (on land it is categorized by the physical effects it has on vegetation and structures) of the Beaufort Wind Force Scale
