Why does it get muggy after the rain?

Thunderstorms often occur in most areas in midsummer. Thunderstorm requires high ground temperature and high air humidity. The ground is hot, and the air temperature near the ground can rise very high, thus floating into the sky; The air humidity is high, and the humid air can rise to the sky to form thunderstorm clouds. Thunderstorms only occur when there are thunderclouds. When the atmospheric temperature is high and there is a lot of water vapor, it is difficult for the water on the ground to evaporate and the sweat on people's bodies to dry, so they will feel bored. Bathing in the bathroom will also feel hot and stuffy, also because of the high temperature and steam in the bathroom. So sultry weather means more water vapor and higher temperature in the atmosphere, which means a thunderstorm is about to happen. Sometimes the weather is sultry, but there is no thunderstorm. This is because the scope of thunderstorms in summer is not large, and thunderstorms may have landed elsewhere.
