Why is the air pressure higher on sunny days than on rainy days? What effect does air pressure have on life and production? How to judge the air pressure?

This statement should be reversed. Under the control of low pressure, the airflow moves upward in the vertical direction, and the airflow is cooled during the rising process (the troposphere temperature decreases with the height), and it is easy to condense and form rainy weather when the airflow is cooled. Controlled by high pressure, the airflow sinks in the vertical direction, and it is not easy to rain when heated, so it is sunny.

Air pressure has an impact on the weather and will affect production and life; Secondly, when the air pressure is low, such as the plateau, people will feel hypoxia; When the air pressure suddenly rises, it will increase the risk of heart disease, high blood pressure and so on.

The judgment of air pressure can be measured by barometer, and other situations should be analyzed in detail.
