original question: Which cloud, with a maximum altitude more than or equal to [12000.0], belongs to the same classification as [Cirrus]?
paraphrase: [Cirrus] or cirrus is a type of cloud composed of ice crystals and characterized by thin, thin bands, accompanied by crests. Sometimes these clouds in volute are so extensive that they are virtually indistinguishable from one another, forming a sheet or veil called cirrostratos. Sometimes convection at high altitudes produces another form of cirrus, called cirrocumulus: pattern of small clouds in tufts.
