Is rainy weather low or high?

Low air pressure refers to the air pressure near the ground, which is usually formed on land in summer. The famous low pressure centers are Asia low pressure center (India low pressure) and Azores low pressure center. Low-pressure airflow upward. The higher the air flow, the lower the temperature, so rainfall is formed. Therefore, the low pressure will generally bring strong winds and rainfall to the passing areas. It can alleviate the drought.

The weather controlled by the high-pressure system is sunny, because the air pressure near the ground is high, that is to say, in the vertical direction, the air mainly moves vertically downward. The closer to the ground, the higher the temperature, and the more difficult it is for water vapor in the air to cool and condense to form precipitation. So it's sunny. Just like our usual autumn weather, it is controlled by high-pressure system many times.

Extended data:

Low air pressure has two main effects on human body:

1, pressure effect caused by low pressure;

2. Hypoxia effect caused by the reduction of atmospheric oxygen partial pressure. The latter has more important physiological and clinical significance.

Effects of Hypobaric Hypoxia on the Body

Hypobaric hypoxia at high altitude can have a series of extensive and specific effects on the body's function and metabolism, which are manifested at all levels and levels. The degree and result of its influence are not only related to altitude, but also depends on the speed of entering the plateau, the residence time and the functional metabolic state of the body.
