Brief introduction of wind speed The flow of air forms wind, and the flow of air is fast or slow. Therefore, the wind generates speed because of the difference between large and small atmospheric pressure. The calculation of wind speed is based on the number of meters flowed per second. The minimum wind speed is less than one meter, and the maximum wind speed even exceeds 60 meters per second. Wind speed can affect climate, nature ... Indoor wind speed also affects human health.
The strength of the wind is usually expressed by the wind level, and the wind level can be estimated by the situation where the ground or sea objects are blown by the wind. At present, the internationally accepted wind power estimation is based on the Beaufort wind level.
The following table is the Bofu wind table:
Wind class name Wind speed (meters per second) Wind class name Wind speed (meters per second)
0 Static <0.3 9 Gale 20.8 ~ 24.4
1 Soft wind 0.3 ~ 1.5 10 Strong wind 24.5 ~ 28.4
2 Light wind 1.6 ~ 3.4 11 Storm 28.5 ~ 32.6
3 Breeze 3.5 ~ 5.4 12 Hurricanes 32.7 ~ 36.9
4 Japanese breeze 5.5 ~ 7.9 13 37.0 ~ 41.4
5 Breeze 8.0 ~ 10.7 14 41.5 ~ 46.1
6 Strong wind 10.8 ~ 13.8 15 46.2 ~ 50.9
7 Blast 13.9 ~ 17.1 16 51.0 ~ 56.0
8 Gale 17.2 ~ 20.7 17 56.1 ~ 61.2
Wind effect
1. The wind speed is 63 kilometers per hour (17.2 meters per second) or above to 117 kilometers (32.6 meters per second)
There is a mild typhoon in between, which in turn affects the climate.
2. The wave system is formed by wind blowing on the sea surface. The length, intensity, and time of the wind blowing determine the size of the waves and affect the safety of fishing, marine sports, and marine entertainment.
4. The performance and practice of many outdoor sports are greatly affected by wind speed, for example: boating, hiking, climbing, surfing,
Golf, baseball ...
5. HAVC refrigeration air conditioner: the air outlet of the cold air, the strength of the wind will affect the indoor temperature, human health and energy efficiency.
6. Industrial machinery also generates wind and affects the surrounding environment.
