    Clouds are classified into different types based on their appearance, height in the atmosphere, and the processes that form them. The International Cloud Atlas, maintained by the World Meteorological Organization (WMO), categorizes clouds into several main types. Here are the basic cloud types:

    1. Cirrus Clouds: These are high-altitude clouds that appear thin, wispy, and white. They are composed of ice crystals and are often seen in the form of delicate, feathery strands or filaments.

    2. Cumulus Clouds: Cumulus clouds are large, puffy clouds with a distinct cauliflower-like shape. They have a flat base and a rounded top and are commonly associated with fair weather. However, they can develop into more vertically developed clouds, such as cumulonimbus clouds, which bring thunderstorms.

    3. Stratus Clouds: Stratus clouds are low-altitude clouds that cover the sky in a uniform layer. They appear as a gray or white sheet-like layer and often bring overcast conditions. Light mist or drizzle may be associated with stratus clouds.

    4. Nimbus Clouds: Nimbus clouds are often used as a prefix to describe clouds that bring precipitation. For example, nimbostratus clouds are dark, and thick, and produce steady, widespread precipitation, such as rain or snow.

    5. Alto Clouds: Alto clouds are medium-altitude clouds found between approximately 2 to 7 kilometers (6,500 to 23,000 feet) above the ground. They include two main types: altocumulus clouds, which are white or gray and appear as rounded masses; and altostratus clouds, which are gray or blue-gray and cover the sky with a uniform layer.

    6. Stratocumulus Clouds: Stratocumulus clouds are low-level clouds that appear as a patchy layer of white or gray clouds. They usually have a lumpy or wavy appearance and are often seen during fair weather conditions.

    7. Cirrostratus Clouds: Cirrostratus clouds are high, thin clouds that cover the sky in a sheet-like layer. They typically have a fibrous or milky appearance and can sometimes produce a halo effect around the Sun or Moon.

    8. Cirrocumulus Clouds: Cirrocumulus clouds are high-altitude clouds that appear as small, white, rounded masses or patches. They often have a wavy or mottled appearance and are sometimes referred to as “mackerel sky” due to their resemblance to fish scales.

    These are the basic cloud types, but there are also various combinations and subtypes that further differentiate clouds based on their appearance and characteristics. Clouds play a crucial role in the Earth’s climate system and weather patterns.
