Describe the formative characteristics of advection fogs, valley fog, evaporation fog, and radiation fog along with their usual locations
What will be an ideal response?
Fog is a cloud layer on the ground with visibility restricted to less than 1 km (3,300 ft). Radiation fog results when radiative cooling of the surface chills the air directly above the surface to the dew-point temperature. Advection fog occurs when air in one place migrates to another place where the conditions are right for saturation. For instance, when warm, moist air moves over a cooler ocean current. Valley fog is a type of advection fog, which results from cooler, denser air settling in low-lying areas. Similarly, upslope fog forms as moist air is lifted due to topography and, as a result, adiabatically cools. Evaporation fog forms when cold air lies over a warm water body and water molecules evaporate from the water surface into the cold, overlying air.
