Question

how does temperature affect humidity​

Answer 1

Answer:

If the water vapor content stays the same and the temperature drops, the relative humidity increases. If the water vapor content stays the same and the temperature rises, the relative humidity decreases. This is because colder air doesn't require as much moisture to become saturated as warmer air.

Answer 2

Humidity is water vapor contained in air. At higher temperatures, air can hold more water vapor than the same amount of air at lower temperatures. For example, if a sealed parcel of air experiences a rise in temperature with no addition of water vapor, the relative humidity of the parcel of air decreases because the warmer air is capable of holding more water.

Having lived several years in a place where winter temperatures could reach minus 70 degrees we rarely saw snow fall below about -35 degrees because air that cold could not hold moisture and no moisture equals no snow.
