Clouds
By: Leigan Laughery
Upper Level Clouds
Cirrocumulus- composed of ice crystals, resembles rumbles
Cirrostratus- very thin, composed of ice crystals
small amount of water vapor
Middle Level Clouds
Altostratus- associated with changing weather
2km-6km
composed of liquid water
Lower Level Class
Nimbostratus
Sometimes occur as individual clouds but more often appear as a general forecast often widespread and are associated with somber skies and drizzle rain.
Vertical Clouds
Cumulonimbus
Low base to a height up to 15km
Very active vertical movements in the air
Fog
Radiation Fog- when ground loses heat by radiation, usually at night.
Advection Fog- when warm, moist air moves horizontally over a cold surface.
Upslope Fog- created adiabatic cooling when humid air climbs a topographic slope.
Evaporation Fog- water vapor is added to cold air that is already near saturation.
