What do you mean by clouds like signs of weather?
Clouds are like weather signs, which means that the weather can be predicted by observing clouds. Signboards are usually hung in front of shops to indicate the name or variety of the shops. As a symbol of a store, the cloud has a similar function. Different types and shapes of clouds usually indicate some trends and changes in the weather.
How are clouds formed?
The main component of clouds is water vapor. Water vapor in the atmosphere will condense into small water droplets when it is cold, and it is a cloud when mixed with dust in the atmosphere.
Clouds will continue to form water droplets in the process of change. When the density of water drops exceeds that of air, they will fall. This is what we call "rain".
According to the shape, composition and formation reasons of clouds, clouds can be divided into ten major cloud genera, and according to their height, they can be divided into three cloud systems: high cloud system, middle cloud system and low cloud system.
