Air pressure and weather

Isobaric line: a closed line formed by connecting places with equal air pressure in a certain time on a plane. It can display the high and low distribution of air pressure in space.

You can see the pressure by observing the isobar.

Air pressure and weather: the higher the air pressure, the higher the temperature, mainly anti-cyclone, and the weather is fine.

The smaller the air pressure, the lower the temperature, mainly cyclone and rainy weather.
