Introduction of 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.
Goethe barometer:
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, le barometre Liegeois. This name reflects the origin of many early meteorological glasses, a glass blower in Liege, Belgium.
The weather ball barometer consists of a glass container with a sealed body, half of which is water. A narrow nozzle is connected to the main body under the water surface and is higher than the water surface. Narrow vents open to the atmosphere. When the air pressure is lower than the human body seal, the water level in the spout will rise above the human body water level; When the air pressure rises, the water level of the spout will drop below the water level of the body. This change of barometer can be easily realized at home.
