How is rain made?. The sun has been warming the ground all morning.. The ground warms the air and the temperature rises. The warm air rises.. As the warm air rises, it cools and the water vapour (tiny droplets of water) in the air condenses to form clouds.. Wang, C.-C., and D. J. .

For it to fall as a raindrop the cloud droplet must get bigger. One raindrop = about 1 million cloud droplets, .
