The evaporation of the sweat absorbs heat from your body and uses it to transform the liquid water to water vapor. Because cooler air is less dense than warm air, the cool air near the surface does not rise, and the air does not mix.
Temperature inversions tend to trap air pollution near the surface.
In Durango, temperature inversions occur in the early morning in late fall and early winter, when radiational cooling of the ground occurs in the valley over night. As day progresses, the ground warms up and the inversion disappears, but early in the morning you can see smoke hanging over the valley. Explain how clouds form. Moist air rises Rising air cools, eventually to temperatures below the dew point for that air parcel. Water or ice condenses around dust, smoke, and salt particles in the air.
