In space, there is a nearly complete vacuum so the air pressure is zero. On Earth, because there are many miles of air molecules stacked up and ...Barometric pressure is a measurement of the air pressure in Earth's atmosphere. For this reason, it is also known as atmospheric pressure. The pressure is created by fluid gas molecules in the air, and it extends in all directions. Notably, it exists as downward pressure exerted on the ground on Earth, which makes it relatively easy to measure.Barometers are used to predict the weather. ­A barometer measures air pressure: A "rising" barometer indicates increas­ing air pressure; a "falling" barometer indicates decreasing air pressure.

Barometers have to be adjusted for changes in altitude in order to make accurate atmospheric pressure readings. Types of Barometers Mercury Barometer. The mercury barometer is the oldest type of barometer, invented by the Italian physicist Evangelista Torricelli in 1643. Torricelli conducted his first barometric experiments using a tube of water.Barometers using mercury are heavy and fragile. The idea of a "dry" barometer was conceived by Gottfried Wilhelm Leibniz around 1700. It would be a way to detect pressure changes using sealed bellows. The first working version of an aneroid (without water) barometer was built in 1843 by French scientist Lucien Vidie.

A falling barometer reading usually indicates that a storm or wet weather is approaching. A more rapid change indicates the weather will change sooner. A barometer reading that rem...Nov 24, 2023 · Barometer is a device for monitoring atmospheric pressure, primarily used for weather forecasting and altitude calculations.

An aneroid barometer is a device used for measuring atmospheric pressure without the use of fluids. It typically consists of a sealed, flexible metal box known as an aneroid cell. This cell is designed to expand and contract with changes in atmospheric pressure. The aneroid cell is made from an alloy that is sensitive to pressure changes.

Updated March 29, 2023. By David Green. Barometric pressure (also called atmospheric pressure) is the measure of air pressure in a given area. Air pressure is the weight of air pressing down on a specific area, and it is measured with an instrument called a barometer. These measurements are affected by air density, which changes based on ...

A barometer measures atmospheric pressure. The air in the atmosphere exerts a force called pressure that constantly changes due to moving weather systems.
