Is 31 km/h wind strong

The Beaufort Scale is an empirical measure that relates wind speed to observed conditions at sea or on land.

Health, Earth Science, Meteorology. 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 The Beaufort scale goes all the way to 17, but the last five numbers only apply to tropical typhoons. These numbers are only used in the areas around China and Taiwan. In , he devised a method of describing wind force according to procedures for setting sails on a warship.

Widespread damage to vegetation and buildings; there's nearly no visibility at sea.

Small wavelets, ripples formed but do not break: A glassy appearance maintained. Small waves - becoming longer; fairly frequent white horses. Sea heaps up and white foam from breaking waves begins to be blown in streaks along direction of wind. Moderately high waves of greater length; edges of crests begin to break into spin drift; foam is blown in well-marked streaks along the direction of the wind. High waves; dense streaks of foam; crests of waves begin to topple, tumble and roll over; spray may affect visibility. Very high waves with long overhanging crests; the resulting foam in great patches is blown in dense white streaks; the surface of the sea takes on a white appearance; the tumbling of the sea becomes heavy with visibility affected.

Occasionally, a light breeze will turn into a strong, persistent wind that makes just staying on your feet a battle. We all experienced them. But what are these gale force winds, and what are their characteristics? According to the Beaufort Scale, gale force winds can be divided into four subcategories. Strong gusty winds are not uncommon and can be found in many major storm systems like hurricanes, thunderstorms, and tornadoes. Gale force winds are not limited to just major storm systems, though. The strong, persistent gale force winds we are discussing in this article are the prolonged gale force winds with gusts strong enough to cause significant structural damage and the ability to literally blow you off your feet. These winds can sometimes occur without any apparent presence of a strong weather system and can last a whole day. One needs to investigate further and find out what exactly these gale force winds are to understand what is causing them in the first place. The introduction already provided a brief description of what a gale force wind is.

Its full name is the Beaufort wind force scale. The scale that carries Beaufort's name had a long and complex evolution from the previous work of others including Daniel Defoe the century before to when Beaufort was Hydrographer of the Navy in the s, when it was adopted officially and first used during the famed "Darwin voyage" of HMS Beagle under Captain Robert FitzRoy , who was later to set up the first Meteorological Office Met Office in Britain giving regular weather forecasts. Beaufort succeeded in standardising the scale. The initial scale of 13 classes zero to 12 did not reference wind speed numbers but related qualitative wind conditions to effects on the sails of a frigate , then the main ship of the Royal Navy , from "just sufficient to give steerage" to "that which no canvas sails could withstand". The scale was made a standard for ship's log entries on Royal Navy vessels in the late s and was adapted to non-naval use from the s, with scale numbers corresponding to cup anemometer rotations.

They will best know the preferred format. The steps of the Beaufort Scale are relatively linear to the wind speeds. Small trees in leaf begin to sway; crested wavelets form on inland waters. So you can find the current version of the Beaufort scale in the table before. In the table you will find the effects on the land. However, this variant is no longer used.
