This method expresses wind strength by describing the effect of wind on landmarks. Everyone can imagine rising smoke, rippling water, or a waving flag. Beaufort shows the strength of the wind on a scale from 0 to 12 with a vivid description of these .
Wind is created by air pressure differences. Air always moves from a place of higher pressure to a place of lower pressure. The movement of air is the wind itself. The resulting pressure differences can range from small areas to continents. The wind direction is given in ° degrees, where 0 and 360 degrees mean the air current coming from the North. The 90 degree wind therefore blows from the east. The direction of the wind is also influenced by landmarks and the Coriolis effect resulting from the rotation of the earth. Its speed is expressed in m/s meters per second or km/h or miles per hour. In physics and meteorology am/s is accepted. The strength of the wind can also be expressed by a less well-known and not so widely used method today, the Beaufort scale.
