Relative to lower temperatures, high temperatures require moisture to fully saturate the air.

Explanation:

As hot air expands it rises and cool air contracts as it has high density if the saturated air is warm it can hold more water and thus the warm air is used to dry the objects and it absorbs more moisture. The opposite is also true for the sinking air which is dense. Such air is compressed in a zone of high pressure. The expanding air cools, which forces it to lose its moisture as rain or snow.  Thus the air is said to be saturated when it's at the 100 percent relative humidity it contains the maximum amount of the moisture possible at that given temperature.
