Bookmark or Share- What Is A Barometer, How It Works, Where To Place It ...A barometer is defined as a meteorological instrument used to measure air pressure in the atmosphere. It forms a critical part of any weather station and is primarily used with other sensors to measure current and determine future weather conditions.
- Barometer - WikipediaA barometer is a scientific instrument that is used to measure air pressure in a certain environment. Pressure tendency can forecast short term changes in the weather. Many measurements of air pressure are used within surface weather analysis to help find surface troughs, pressure systems and frontal boundaries.
- How Is Barometric Pressure Measured and Why? - HowStuffWorksWhat Is a Barometer? A barometer is a scientific instrument designed to measure barometric pressure. Barometers as we know them date back to 1643 when the Italian inventor Evangelista Torricelli measured air pressure using a glass tube filled with mercury and open on its downward-pointing end.
- What does it mean when a barometer is rising or falling?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. In space, there is a nearly complete vacuum so the air pressure is zero.
- How do barometers work? - Explain that StuffInstruments that measure air pressure are called barometers and people have been using them for weather forecasting and scientific research for hundreds of years. Let's take a closer look at how they work!
