High Clouds (5-13 km):
* Cirrus (Ci): Wispy, delicate clouds composed of ice crystals. They often have a feathery appearance and are associated with fair weather.
* Cirrocumulus (Cc): Small, white, puffy clouds arranged in rows or patches. They look like ripples on the surface of a lake.
* Cirrostratus (Cs): Thin, sheet-like clouds that often cover the entire sky. They can create halos around the sun or moon.
Mid-Level Clouds (2-7 km):
* Altocumulus (Ac): White or gray patches of clouds with rounded masses. They often have a wave-like appearance and can be associated with rain or snow.
* Altostratus (As): Gray or bluish sheets of clouds that cover the entire sky. They can be so thick that they block out the sun.
* Nimbostratus (Ns): Dark, gray, rain-producing clouds that often cover the entire sky. They are associated with steady, widespread rain or snow.
Low Clouds (Surface-2 km):
* Stratocumulus (Sc): Gray or white patches of clouds arranged in rolls or rounded masses. They are often associated with fair weather or light rain.
* Stratus (St): Gray, featureless sheets of clouds that cover the entire sky. They can be associated with drizzle or fog.
* Cumulus (Cu): White, fluffy clouds with flat bases. They are associated with fair weather or showers.
* Cumulonimbus (Cb): Towering, thunderhead clouds that produce heavy rain, lightning, and hail. They are associated with severe thunderstorms.
Other Cloud Types:
* Lenticular: Lens-shaped clouds that often form over mountains.
* Mammatus: Rounded pouches that hang from the underside of clouds, often cumulonimbus clouds.
* Pileus: A cap-like cloud that forms above a cumulus or cumulonimbus cloud.
This is a simplified overview, and there are many variations within each cloud type. Cloud identification can be a complex process, but understanding these basic categories is a good starting point.
