First, the wind direction measurement
Wind vane is the main tool for measuring wind direction. This is a sign with arrows pointing in different directions. The direction of the arrow represents the source of wind, and the length of the arrow represents the wind speed. Wind vane senses wind direction and wind speed through sensors.
Second, the wind speed measurement
Anemometer is the main tool for measuring wind speed, which includes a three-cup rotor and a pair of photoelectric sensors. When the wind blows, the rotor will rotate, and the photoelectric sensor will sense the rotation speed and convert it into an electrical signal for output. The output electrical signal can be used to calculate the wind speed.
Third, the advantages of wind direction and wind speed measurement
1, high accuracy: these two tools have high measurement accuracy and can accurately reflect wind speed and direction.
2. Good stability: These two tools have good stability and can work stably in different climatic conditions.
3. Real-time monitoring: These two tools can monitor the change of wind in real time and provide timely and accurate data for weather forecast.
4. Convenient maintenance: these two tools have low maintenance cost and long service life, which can meet the needs of long-term use.
The influence of wind on life
1, climate impact
Wind is one of the important factors of climate change, which can bring warm air or cold air into an area, thus affecting the temperature and rainfall in the area. Rainfall in monsoon climate zone is affected by monsoon intensity, and strong wind may lead to disasters such as rainstorm and flood.
2. Traffic impact
Wind will affect people's travel, especially in the case of high wind speed. Strong wind may make the plane unable to take off and land normally, affecting air traffic. At sea, strong wind may make the ship unable to sail or cause capsizing, which will have an impact on maritime traffic.
3. Environmental impact
Wind can affect the growth of plants and the migration of animals. In some cases, strong winds may lead to bad weather phenomena, such as sandstorms, which will destroy the environment and ecology.
4. Use of energy
Wind energy is a clean and renewable energy. In appropriate areas, wind power can be used to meet energy demand. Strong wind can also be used for aerodynamic research and wind power generation test.
