Question

Quizplus · Accepted Answer

Cooling of a surface overnight that chills the air layer directly above that surface leads to the development of a radiation fog. This type of fog forms due to the radiation cooling of the surface at night which then cools the adjacent air layer to below its dew point, leading to the condensation of water droplets and the formation of fog. Advection fog forms when warm, moist air moves over a cooler surface. Evaporation fog occurs when water vapor is added to the air by evaporation from a water surface, and the air is then cooled to the dew point. Upslope fog forms when moist air rises and cools adiabatically as it moves up a slope.
