Wind levels are divided into 18 levels.
Wind scale (wind scale), referred to as wind level, is a method of expressing wind intensity. Wind force refers to the force exerted by wind blowing on an object. Generally, the wind force is divided into 13 levels based on the various phenomena caused by the wind blowing on objects on the ground or water surface. The minimum is level 0 and the maximum is level 12. Winds of level 12 are particularly dangerous.
According to the national standards issued by China in June 2012, based on the wind speed at a height of 10 meters at the standard meteorological observation site, the wind power level is divided into 18 levels. There are three commonly used units for expressing wind speed, respectively. They are nautical miles per hour, meters per second, and kilometers per hour. The commonly used units for typhoon forecasting in China are meters per second. Wind is an important resource.
Benefits of wind power
1. Environmental protection: Wind power is a renewable and clean energy that does not produce pollutants and does not It emits greenhouse gases and has a small impact on the environment. Compared with traditional fossil fuel power generation, wind power is more environmentally friendly.
2. Energy diversity: Wind energy is an abundant energy source that is not restricted by geography or resources and can be widely utilized around the world. Wind power can provide diversified energy supply, reduce dependence on fossil fuels, and improve energy security.
3. Economic benefits: Wind power is an economically feasible energy source. With the advancement of technology and the realization of economies of scale, the cost of wind power has gradually decreased, becoming a competitive energy source. At the same time, wind power can also bring jobs and tax revenue to the local economy.
4. Promote the development of renewable energy: Wind power is an important part of the development of renewable energy. By promoting wind power, we can promote the research and development and application of renewable energy technologies and promote the transformation and upgrading of the energy structure.
