Clouds and Precipitation

Clouds and Precipitation. Air Masses. Pg 480. Humidity. Humidity is a measure of the amount of water vapour in the air. The warmer the temperature of air, the more water the air can hold.

Water in the atmosphere

Water in the atmosphere. Water in the atmosphere exists in all 3 forms: solid, liquid, and vapor. Ice can change to water and then to vapor if heat is added to it. Ice can also change directly to vapor in a process known as sublimation if it is below freezing and the air is very dry .
