Answer
Absolute humidity is the amount of moisture actually contained in air of a certain size at any given time.
It is expressed in cubic meters / gram.
Air diffusion and compression change the absolute humidity of the air.
It changes according to place and time.
Absolute humidity is highest at the equator and lowest at the poles.
It is more on the seas and less and less as we move away from the sea.
Absolute humidity is higher in summer than at night and in winter than at night.
The relative humidity expressed in percent can be found by the following formula.
Relative humidity $=\frac{\text { Humidity in air of a certain size at a certain temperature. }}{\text { Ability to absorb moisture of the same size at the same temperature. }}$
The relative humidity of the air also fluctuates with fluctuations in temperature.
Relative humidity is higher as early morning and night temperatures remain low.
The relative humidity is low as the temperature stays higher in the afternoon.
The relative humidity is higher in the air of the seas as well as in the open air than in the land.
