List of cloud types
The list of cloud types groups the tropospheric types as "high" (cirrus, cirrocumulus, cirrostratus), "middle" (altocumulus, altostratus), "multi-level" (nimbostratus, cumulus, cumulonimbus), and "low" (stratocumulus, stratus) according to the altitude level or levels at which each cloud is normally found. Small cumulus are commonly grouped with the low clouds because they do not show significant vertical extent. Of the multi-level genus-types, those with the greatest convective activity are often grouped separately as "towering vertical". The genus types all have Latin names.
Traditional patterns of Korea
Cloud patterns are divided into three shapes. The first shape is clouds being blown in the wind, the second shape is clouds floating in the sky, and the third is scattered and dotted clouds. These shape of cloud patterns were different by era. Each pattern reflected different social backgrounds.
