What explanation methods are used in "Looking at the Clouds to Know the Weather" and giving examples from the original text

Use an analogy, copy the appearance, classify, quote information, list numbers, make comparisons

For example:

Cirrus clouds are floating in strands, Sometimes it looks like a white feather, sometimes it looks like a piece of white silk. ——For example

If cumulus clouds quickly bulge upward and form tall cloud mountains with peaks reaching the zenith, they become cumulonimbus clouds. ——Appearance

In summer, after the rain and the sky clears up, a colorful arc will often hang on the cloud curtain opposite the sun. This is a rainbow. ——For example

People often say: "The east rainbow booms and the west rainbow rains." It means that if the rainbow is in the east, there will be thunder but no rain; if the rainbow is in the west, there will be heavy rain. ——Quotation, interpretation

There is also a kind of cotton-like white cloud called cumulus cloud, which often appears in the sky about two thousand meters.
