How many kinds of clouds are there in meteorology?

In meteorology, all kinds of clouds in the atmosphere are divided into 3 families 10 genera and 29 categories according to their height, characteristics and properties. The first family is called Gao Yun. The high clouds are divided into three genera: Cirrus, cirrostratus and cirrocumulus, and can be subdivided separately. For example, cirrus clouds are divided into cirrus clouds, dense cirrus clouds, pseudo cirrus clouds and hooked cirrus clouds, so it is not necessary to elaborate.

The second group of clouds is the medium cloud. Middle clouds are divided into cumulus clouds and stratocumulus clouds. Ultra-high cumulus clouds are dense clouds or tiled, fish-scale or wavy clouds. High-level clouds are clouds with stripes or fiber structures. The clouds are relatively uniform, and the clouds are usually gray or grayish white, with continuous or intermittent rain and snow. The height of the cloud bottom of these two genera is generally 2.5 km -4.5 km.

The third is low cloud. Low clouds are divided into five genera: cumulonimbus, cumulonimbus, stratocumulus, stratocumulus and nimbostratus. Stratocumulus and nimbostratus are sporadic clouds that often produce precipitation, and rarely appear in the arid areas of northwest China. Cumulonimbus clouds and cumulonimbus clouds are the most common in low clouds, and their similarity is that the convective movement up and down in the clouds is relatively strong. Due to convection, the top of cumulus clouds overlap in an arc shape, and the bottom is almost horizontal. Cumulonimbus cloud evolved into cumulonimbus cloud in its heyday. The bottom of cumulonimbus clouds is dark and chaotic, with obvious ups and downs, and is often suspended in a spherical shape. "Dark clouds crush cities and cities are destroyed" is what the cumulonimbus cloud said. Cumulonimbus clouds often appear in summer, and weather phenomena such as lightning, hail, showers, even heavy rain and sudden strong winds often appear in cumulonimbus clouds.
