classes of clouds are not based on altitude
|
Detailed explanation-1: -Clouds are classified according to their height above and appearance (texture) from the ground. The following cloud roots and translations summarize the components of this classification system: 1) Cirro-: curl of hair, high; 2) Alto-: mid; 3) Strato-: layer; 4) Nimbo-: rain, precipitation; and 5) Cumulo-: heap.
Detailed explanation-2: -In addition to standardizing the genus-species system, the WMO also classified clouds by altitude and divided the troposphere into 3 levels: Low-level Clouds: < 6, 500 ft. Mid-level Clouds: 6, 500 to 23, 000 ft. High-level Clouds: 16, 500 to 45, 000 ft.
Detailed explanation-3: -Low-Level Clouds. Cumulus (Cu), Stratocumulus (Sc), Stratus (St), and Cumulonimbus (Cb) are low clouds composed of water droplets.
Detailed explanation-4: -Low clouds span up to 6, 000 feet in altitude. Middle or mid-level clouds usually are around 10, 000 feet in altitude and are associated with the ‘alto-’ prefix. High clouds are often 20, 000 feet or higher and have a ‘cirro-’ prefix.
