Document Summary
Has to persist for a while in order for it to accumulate into a rain droplet: dominant mechanism in warm clouds. Moisture is in the liquid form these clouds are usually found in tropical area: liquid water is needed to form larger droplets. More input of water droplets than the evaporation of water in a crystal makes the ice crystal grow larger. Fog: a type of cloud, clouds that are in contact with the ground, comprised of tiny moisture droplets there needs to be a mechanism for fog to form, two types of mechanisms, advection fog. Can form when we have a mass of air that moves to some area to chill it down to the dew point. Evaporation fog: another type of advection fog, relatively cool air moving over a warm body of, radiation fog water. Air does not move horizontally; chills in place as a result of radiation cooling. Often is experienced in louisiana in the mornings.
