Which Instrument Is Used to Measure Wind Speed?
Wind speed measurement is crucial in meteorology, aviation, and environmental monitoring. The primary device for this task is an anemometer, which accurately gauges wind velocity and direction.
Types of Anemometers
Common varieties include cup, vane, hot-wire, and ultrasonic anemometers. Each type suits specific applications, from weather stations to industrial settings.
How Anemometers Work
Cup anemometers rotate with wind flow, measuring speed via rotation count. Vane types align with wind direction, while ultrasonic versions use sound waves for precision.
Frequently Asked Questions
What units measure wind speed?
Meters per second (m/s), kilometers per hour (km/h), or miles per hour (mph) are standard.
Can smartphones measure wind speed?
Dedicated external sensors are needed for accuracy; built-in phone sensors are unreliable.
