High-Level Clouds (5,000 - 13,000 meters / 16,000 - 43,000 feet):
* Cirrus (Ci): Delicate, wispy clouds composed of ice crystals.
* Cirrocumulus (Cc): Small, white, puffy clouds arranged in rows or patches.
* Cirrostratus (Cs): Thin, sheet-like clouds that often cover the entire sky and can produce halos around the sun or moon.
Mid-Level Clouds (2,000 - 7,000 meters / 6,500 - 23,000 feet):
* Altocumulus (Ac): White or gray patches of clouds that are often arranged in layers or sheets.
* Altostratus (As): Grayish or bluish sheet-like clouds that can cover the entire sky and often obscure the sun.
Low-Level Clouds (Surface - 2,000 meters / 0 - 6,500 feet):
* Stratocumulus (Sc): Gray or white patches of clouds that are often arranged in rolls or rounded masses.
* Stratus (St): Uniform, gray, sheet-like clouds that can cover the entire sky and often produce drizzle or light rain.
* Nimbostratus (Ns): Dark, gray, rain-producing clouds that can cover the entire sky and often produce continuous rain or snow.
Vertical Clouds (Extending from low to high levels):
* Cumulus (Cu): White, puffy, cotton-like clouds that often have a flat base and a rounded top.
* Cumulonimbus (Cb): Tall, towering clouds that are associated with thunderstorms and can produce heavy rain, hail, strong winds, and tornadoes.
Additional Cloud Types:
* Lenticular Clouds: Lens-shaped clouds that form over mountains.
* Mammatus Clouds: Rounded, pouch-like clouds that hang from the underside of cumulonimbus clouds.
* Pileus Clouds: Cap-like clouds that form above cumulus or cumulonimbus clouds.
It's important to note that these are just the main cloud types. There are many variations and combinations of these clouds, and new cloud formations are constantly being observed.
