original question: Which cloud, with a maximum altitude more than or equal to [12000.0], belongs to the same classification as [Cirrus]?
answer: cirrostratus, cirrocumulus
answer type: Cloud.
auxiliary information: Cirrus is a genus of atmospheric cloud generally characterized by thin, wispy strands, giving the type its name from the Latin word cirrus meaning a ringlet or curling lock of hair. The strands of cloud sometimes appear in tufts of a distinctive form referred to by the common name of "mares' tails". On planet Earth, cirrus generally appears white or light gray in color. It forms when water vapor undergoes deposition at altitudes above 5,000 m in temperate regions and above 6,100 m in tropical regions. It also forms from the outflow of tropical cyclones or the anvils of cumulonimbus cloud. Since cirrus clouds arrive in advance of the frontal system or tropical cyclone, it indicates that weather conditions may soon deteriorate. While it indicates the arrival of precipitation, cirrus clouds only produce fall streaks. Jet stream-powered cirrus can grow long enough to stretch across continents while remaining only a few kilometers deep. When visible light interacts with the ice crystals in cirrus cloud, it produces optical phenomena such as sun dogs and haloes. Cirrus is known to raise the temperature of the air beneath the main cloud layer by an average of 10 ¬∞C.
What is the cloud belonging to the same classification as [Cirrus] that has a maximum altitude greater than or equal to [12000.0] called?
