Under what condition can an air mass become stable and produce widespread mist or low clouds?
Answer and explanation
Correct answer: When moist air moves slowly over a cold surface
When moist air moves slowly across a colder land or water surface, it is cooled from below. Cooling increases relative humidity and may bring the air to saturation, while the stable layering suppresses strong vertical mixing. Condensation near the surface can then produce widespread mist, fog, or low stratus cloud.
