Wind velocity is measured by -

The correct answer is Anemometer.

Key Points

• Anemometer is an instrument used to measure wind speed and velocity.
• It is widely used in meteorology for weather forecasting and climate studies.
• Modern anemometers can measure both the speed and direction of the wind.
• The basic principle of an anemometer involves wind pressure or motion being converted into measurable data.
• Examples of anemometers include cup anemometers, vane anemometers, and hot-wire anemometers.

Additional Information

• Barometer:
  • A barometer measures atmospheric pressure.
  • It is crucial for weather prediction and determining altitude.
• Hygrometer:
  • A hygrometer measures the humidity (moisture content) in the air.
  • It is used in meteorology, agriculture, and HVAC systems.
• Maximum-Minimum Thermometer:
  • This thermometer records the highest and lowest temperatures over a period.
  • It is commonly used in weather stations and laboratories.
• Wind Measurement Importance:
  • Wind speed data is vital for aviation, marine navigation, and renewable energy projects like wind turbines.
  • It helps in understanding weather systems and mitigating the impacts of storms or cyclones.
