Are Higher Elevations Less Humid?

On average, moisture availability (both relative humidity and absolute vapor pressure) decreases with elevation, but the seasonal and diurnal variability in relative humidity (RH) is enhanced toward the mountain summit. ... This is borne out by the reduction in cloud amounts (using a surrogate threshold of RH .

Why is it more humid at higher altitudes?

The higher the altitude, the more efficiently water vapor traps heat. Minschwaner and Dessler's model describes how the humidity of the upper troposphere changes as the surface warms. As the Earth warms, more water is expected to evaporate from the surface.

Are Mountains less humid?

Temperatures on mountains become colder at high elevations, due to the way that the sun heats the surface of the Earth. Humidity decreases with altitude, so generally mountains aren't very humid. ... And Mountains have cooler temperatures at higher elevations with little humidity.
