The water vapor present in the atmosphere is called humidity. This humidity is the basis of daily seasonal change.
Types of humidity:
The main types of humidity are as follows:
1. Absolute humidity: It is also called the real humidity, the amount of water vapor that is found at a certain temperature in a fixed volume of air is called the real or absolute humidity.
2. Relative humidity: Relative humidity is the ability of air to absorb moisture at a certain temperature and a fixed volume.
3. Specific humidity: When the air rises up and comes down, there is change in its actual humidity. Therefore, in the study of air masses, specific humidity is used in place of actual humidity.
