The wind level comparison table includes wind speeds from 0 to 12, as follows:
Level 0, no wind, wind speed wind 0.0-0.2 meters/second
Level 1, gentle wind, wind speed 0.3-1.5 m/s;
Level 2, light wind, wind speed
p>3 Level 4, light breeze, wind speed 3.4-5.4 m/s;
Level 4, light breeze, wind speed
Level 5, fresh wind, wind speed 8.0-10.7 meters/second;
Level 6, strong wind, wind speed 10.8-13.8 meters/second;
Level 7, strong wind, wind speed 13.9 -17.1 meters/second;
Level 8, strong wind, wind speed 17.2-20.7 meters/second;
Level 9, gale, wind speed 20.8-24.4 meters/second; /p>
Level 10, strong wind, wind speed 24.5-28.4 meters/second;
Level 11, storm, wind speed 28.5-32.6 meters/second
Level; 12, typhoon or hurricane, wind speed 32.7-36.9 meters/second.
Prstrong wind precautions
First of all, pay attention to fire prevention. The wind is strong and the material is dry, and the risk of fire is high. Pay attention to fire safety in windy weather. It is necessary to strengthen the cleaning of flammable materials and keep them away from fire sources; it is strictly prohibited to burn paper, waste and straw outdoors to avoid fire accidents, check the environment frequently for fire hazards and eliminate them in time; once discovered.
Second, we must avoid the “narrow tube effect”. When walking or cycling, avoid walking in long and narrow passages between high-rise buildings, because long and narrow passages will create a "narrow tube effect" and the wind will increase in the passage, thereby posing certain dangers for pedestrians.
Third, make atBeware of falling objects at high altitude. Some billboards may collapse due to improper installation in strong winds; some old tree trunks are dead and have weak foundations, and can break in strong winds, posing a danger to air conditioners, flower pots and other equipment stored at high altitudes. high-risk items that can cause injuries, as well as some glass curtain walls, exterior wall tiles and other aging high-rise building materials, also have hidden dangers of falling and injury.
