A barometer is a device used to measure atmospheric pressure. Because atmospheric pressure changes with distance above or below sea level, a barometer can also be used to measure altitude. There are two main types of barometers: mercury and aneroid. Learn more about barometers in this article. What is a Barometer? A barometer is an instrument used to measure the air pressure as it varies with distance, either above or below sea level. Wind is essentially air moving from high-pressure areas to low-pressure areas. How Do Meteorologists Use Barometers? Meteorologists use barometers as part of a broader set of tools to predict the weather. By regularly measuring air pressure, they can identify trends and patterns that indicate upcoming weather changes. Discover the primary function of a barometer: measuring atmospheric pressure. Understand how this vital weather instrument works and its importance in forecasting.
