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. 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. Please note that these are mean speedsusually averaged over 10 minutes by convention, and do not capture the is 31 km/h wind strong of wind gusts.

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.

Is 31 km/h wind strong

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. Sea completely white with driving spray; visibility very seriously affected. What is the Beaufort Scale? St Lucia, QLD. Ulladulla, NSW. Geelong, VIC. Willetton, WA. News Articles Events.

The Beaufort scale is the most common scale for classifying and naming winds according to their speed. The scale was named after Sir Francis Beaufort - However, the man did not contribute much to the development of the scale. If a wind force is mentioned without the addition of a special scale, it is usually related to the Beaufort scale. Thus, information on wind speeds in weather forecasts or in logbooks usually refers to the Beaufort Scale as well. The current version of the scale was defined in with 13 wind speeds.

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".

Wave crests topple over, and spray affects visibility. The Beaufort scale is the most common scale for classifying and naming winds according to their speed. Gentle breeze at kph mph.

Larger waves form, whitecaps prevalent, spray. Wind conditions consistent with a wind advisory. Sustained wind speeds of 21 to 25 mph, or frequent wind gusts of 30 to 35 mph.

Moderate waves, taking a more pronounced long form; many white horses are formed - a chance of some spray.
