Is the weather high?

There is no necessary connection between sunny days and temperature. It rains all day in the tropical rain forest area, with high air humidity and low air pressure. The temperature in the Qinghai-Tibet Plateau is very low, but it is often clear in Wan Li in Wan Li.

When the temperature is low, the air drops and gathers, forming high pressure, which makes the air easily flow to the surrounding low pressure, so the moisture with high temperature is not easy to invade, thus forming a sunny day.

When the temperature is high, the air is light and flows upward, and the ground air is thin to form a low pressure, which drives a large amount of water vapor to flow upward and condense into water vapor in the air, making it difficult to appear sunny.
