How is barometer measured
Web7 nov. 2024 · The air around you has weight, and it presses against everything it touches. That pressure is called atmospheric pressure, or air pressure.It is the force exerted on a surface by the air above it as gravity pulls it to Earth. Atmospheric pressure is commonly measured with a barometer.In a barometer, a column of mercury in a glass tube rises … The concept that decreasing atmospheric pressure predicts stormy weather, postulated by Lucien Vidi, provides the theoretical basis for a weather prediction device called a "weather glass" or a "Goethe barometer" (named for Johann Wolfgang von Goethe, the renowned German writer and polymath who developed a simple but effective weather ball barometer using the principles d…
