Anemometer Purpose

An anemometer is a meteorological instrument specifically designed for measuring wind speed. It quantifies the rate at which air is moving.

Key Function

The primary use of an anemometer is to determine wind speed, which is crucial for:

• Weather forecasting
• Aviation safety
• Wind power generation assessment
• Climate studies

Why Other Options Are Incorrect

The other options represent measurements typically taken by different instruments:

• Cloud height is measured using ceilometers.
• Air pressure is measured using barometers.
• Water quality involves assessing various chemical and physical parameters using specialized sensors, not anemometers.
