How does temperature affect humidity?

Answer 1

Temperature does have a direct effect on relative humidity.

( just to make the water vapor move faster when war and slower when cool). As temperature goes up, the ability of the air to hold more gas goes up, so relative humidity goes down (unless more water vapor is being added). very good answer if you don't trust it. i got an A on a take home test with this answer

Temperature affects humidity when they take place in the Dew point when water vapour changes to liquid. At this temperature humidity is high. The higher the temp, the more water vapor can be carried in air.

Thus if you heat air (as is done in the winter) the relative humidity drops ... the air seems dryer even though the total amount of water vapor is unchanged.

Answer 2

Increase temperature will reduce relative humidity.

For the term relative, where the same amount of water vapour contained in air but the air can absorb more water due to elevated temperature.
