GEO E111 Lecture Notes - Lecture 20: Nimbostratus Cloud, Advection, Cirrocumulus Cloud
Document Summary
Type formed when moist air is cooled below dew point as a result of intense radiation on the ground at night: advection fog. Type formed when moist air from the sea moves horizontally over a cold surface e. g. snow covered ground: orographic/hill/upslope fog. Type formed when moist air is cooled after climbing a hill or mountain: evaporation fog. Type formed when water vapour is added to cold air that is already near saturation causing excess water vapour to condense and form fog: frontal fog. Type formed when warm moist air is cooled from below as it rises over a cold air mass: steam fog. Type formed when moist air passes over the surface of a much warmer fresh water body. The warm water is cooled from above and condensing water vapour forms fog. It appears to be steaming: ice fog. Type formed when water vapour is converted directly into ice crystals when temperatures are below freezing point.
