The featured image was taken last month in Pu ' er , Yunnan Province , China . Also captured were unusual cloud ripples above the pileus cloud . The formation of a rare pileus cloud capping a common cumulus cloud is an indication that the lower cloud is expanding upward and might well develop into a storm .
