What does the weather forecast say?

High pressure is sunny and low pressure is rainy. On sunny days, the air pressure in the high-pressure center is high, but the surrounding air pressure is low, and the air in the horizontal direction flows from the center to the surrounding areas, which leads to the decrease of the air density in the air pressure center, forcing the high-altitude air to sink, the airflow to sink, and the water vapor is not easy to condense. Therefore, sunny and dry weather is formed, while low pressure is the opposite.

Not the ground and the sky.
