The atmosphere contains various types of clouds, and there are many classifications. For example, the cirrus clouds are high, thin, and wispy, but they can also be seen in different forms like cirrostratus. Cumulus clouds are fluffy and can indicate good weather, but they can also develop into cumulonimbus clouds, which are storm clouds. Stratus clouds are gray and can lead to light rain, whereas nimbus clouds are not just a type but also a description of rain-bearing clouds. There are also many subtypes, like stratocumulus and altostratus, and clouds can be layered or puffy. This makes cloud classification complex, as there are numerous examples, including cirrostratus, cirrocumulus, and stratus, which can also appear in different weather conditions. Overall, clouds can be classified into several categories based on their formation, height, and precipitation characteristics, but this is just a brief overview.<|im_end|>
