Why does low air pressure produce rainy weather?

Low pressure air is rising. In the rising process, water vapor condenses to form precipitation, such as tropical rain forest formed by equatorial depression, cyclone precipitation, high-pressure air sinking and so on. In the process of sinking, the temperature rises gradually, and the water vapor can't condense, which means the weather is fine.
