CLOUDS
By: Cheinie :)
HIGH CLOUDS!
6KM; Small amount of H2O vapor& low temps. due to the altitude
-Thin white& composed of ice crystals
Cirrus; Cirrocumulus; Cirrostratus
MIDDLE CLOUS
2-6KM; Composed of liquid H2O vapor
Alto- means middle
Altocumulus- settled weather
Altostratus- changing weather
LOW CLOUDS
2KM; Sometimes occur as individual clouds but more often appear as a general overcast.
-Ofter wide spread& are associated with somber skies& drizzly rain
Stratus; Stratocumulus; Nimbostratus
VERTICAL CLOUDS
Low base that extend to heights as much as 15KM indicates very active vertical movements in the air.
Cumulus& Cumulonimbus
FOG
A cloud on the ground there are four types
Radiation Fog, Advection Fog, Upslope Fog, and Evaporation Fog
Radiation Fog- When the ground loses heat through radiation; usually at night, fog condenses in the cool air at the dew point.
Advection Fog- When warm, moist air moves horizontally over a cold surface such as snow-covered found or a cold ocean (from sea to land).
Upslope Fog- Created adiabatic cooling occurs when humid air climbs a topographic slope.
Evaporation Fog- Water vapor is added to cold air that is already near saturation.
