What does barometer mean?

Barometer has five meanings, and the most common one is barometer. Barometer is a scientific instrument used by meteorology to measure atmospheric pressure. Pressure trends can predict short-term changes in the weather. In surface weather analysis, there are many methods to measure air pressure to help find the ground trough, high pressure system and frontal angle.

Barometer and barometric altimeter (the most basic and common altimeter) are essentially the same instrument, but their uses are different. The purpose of the altimeter is to match the atmospheric pressure with the corresponding altitude, while the barometer remains stationary to measure the subtle pressure changes caused by the weather. The main exception is ships at sea, which can use barometers because their height will not change.

Due to the existence of weather system, the plane may need to adjust its altitude when flying between different standard pressure zones. The concept of reducing atmospheric pressure to predict stormy weather provides a theoretical basis for weather forecasting equipment called "weather glass" or "Goethe barometer" (named after Goethe, a famous German writer and learned man, who developed a simple and effective weather use principle through Torricelli barometer).

Some English speakers use French. This name reflects the origin of many early meteorological glasses-glass blowers in Liege, Belgium.
