Why does it rain when it is hot and muggy? Please explain. Thank you. They say there is no water in the air.

The sultry weather means that the air with high humidity rises to a certain height. When it meets cold air, it will condense into water droplets, and the volume of water droplets will gradually increase. If it exceeds the buoyancy of the air, it will fall and collide with each other to become bigger raindrops, forming rainfall. There is moisture in the air, which is invisible to the naked eye and can be measured by a hygrometer.
