Why does the humidity in the air decrease when the weather turns cold?

The higher the temperature, the more moisture produced by evaporation in the air and the greater the humidity in the air.

or vice versa, Dallas to the auditorium The lower the temperature, the less moisture produced by evaporation in the air and the less humidity in the air.

From the point of view of energy, the higher the temperature, the more energy water molecules gain, and they are easy to leave the water surface and evaporate into the air, so the humidity in the air will naturally increase, and vice versa.

Of course, nothing is absolute. If it turns cold because of rain and snow, the humidity in the air will not decrease.
