The state of the atmosphere at any particular time

The amount of moisture in the air

The number of clouds in the sky

The speed of the wind

There is less water in the air at night

The air can hold a lot of moisture

It's all been condensed

Absolute humidity is expressed as a percentage; relative humidity is expressed as a whole number

Absolute humidity is how much water the air can hold; relative humidity represents how much water the air actually holds

Relative humidity makes the air sticky; absolute humidity makes the air dry

Absolute humidity represents how much water the air actually holds; relative humidity is how much water the air can hold
