<P> The list of cloud types is a summary of classifications and photographs . The ten main genus - types in the troposphere are grouped into altitude - levels ; high ( cirrus , cirrocumulus , cirrostratus ) , middle ( altocumulus , altostratus ) , multi-level ( nimbostratus , cumulus , cumulonimbus ) , and low ( stratocumulus , stratus ) . 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 </P>
