" Cumulus humilis " clouds look like puffy, flattened shapes . " Cumulus mediocris " clouds look similar, except that they have some vertical development . " Cumulus congestus " clouds have a cauliflower-like structure and tower high into the atmosphere, hence their alternate name " towering cumulus ".
