Measuring Wind Speed
To measure wind speed, professionals use an instrument called an anemometer. An anemometer typically consists of cups that spin when wind blows, and the speed of rotation is proportional to the wind speed. Another common method is using a wind vane in conjunction with an anemometer to calculate wind direction as well as speed. By understanding the principles behind anemometers, meteorologists and researchers can accurately determine wind speed to make weather predictions and analyze climate patterns.
Measuring Air Pressure
Air pressure can be measured using a device called a barometer. A barometer works by measuring the weight of the air above it in the atmosphere. Changes in air pressure are indicative of weather patterns, such as high pressure typically indicating fair weather and low pressure often signaling the approach of a storm. By monitoring air pressure, meteorologists can forecast weather changes and provide alerts for potential extreme conditions.
