low clouds; below 2000m; gray fog like clouds; flat
clouds that are low-level flat layers of cumulus clouds, that begin to join each other.
Clouds that are low-level, uniform layer, usually very dark, that bring heavy rain or snow.
gray/blue in color; Middle level (6500 – 20,000 ft), gray sheet, thinner layer allows sun to appear as through ground glass. Precipitation: rain or snow.

high level (20,000+ feet), thin, sheet-like, flat clouds that cover the sky.
High Level clouds; Small, round, puffy and can form rows or ripples
found at high altitudes and appear as thin and wispy sheets with feathery appreance made of ice crystals
low level clouds that look like a piece of floating cotton and are associated with good weather
A type of cumulus cloud that is tall and gray, and associated with thunderstorms. They are found in all altitude levels.
