2. Stratocumulus: Stratocumulus has no structure at all, it is composed of tiny water droplets. It often rains or snows in Mao Mao, but it doesn't rain much.
3. Cumulus: A cloud with an arc or arch at the top and almost horizontal at the bottom.
4. Rain cloud: The cloud is as big as a towering mountain, the top begins to freeze, the outline is vague, there is a fiber structure, the bottom is very dark, and there are often rain banners and broken rain clouds.

Characteristics of cumulus clouds:
Hypercumulus clouds are very small, obviously, with different thicknesses and shapes. Thin clouds are white, and the outlines of the sun and the moon can be observed. Thick clouds are dark gray, but the outline of the sun and the moon can't be seen clearly.
Ultra-high cumulus clouds are mostly oblate, flat, fish-scale or wavy dense clouds. The distribution in the sky is often densely arranged in rows or waves, and the viewing angle width of clouds is 1-5.
Cumulus clouds are composed of tiny water droplets or supercooled water droplets mixed with ice crystals. Every day and every month, when passing through the thin cumulus clouds, it is often observed that tiny water droplets or ice crystals in the cumulus clouds diffract light, forming a halo with blue inside and red outside, also known as China.
Ultra-high cumulus clouds are formed under the inversion layer at high altitude, and the cold air is saturated. Clouds are not thick, relatively stable and rarely change, indicating sunny days. The agricultural proverb "Clouds on the tile will burn people" and "There are carp spots in the sky, so you don't need to turn over the sun" means that the sky will clear up after this cumulus cloud appears. If the thickness of the altocumulus continues to thicken and gradually merge into layers, it means that the weather will change and there will even be precipitation.
