THE BIG IDEA
What is happening?
Clouds contain tiny water droplets or ice crystals. Droplets can grow and join together. When they become large enough, they can fall as rain.
Simplified model: This is a playful model with invented thresholds, not a forecast. Real clouds and rainfall form through more complex processes.
