What are the various clouds in the sky and the weather changes they represent? What are the various clouds in the sky and the weather changes they represent?

1. Stratus. The clouds are uniformly layered, gray and foggy, and the cloud base is very low but does not touch the ground. Stratus clouds generally indicate fine weather, with occasional drizzle or light snow.

2. Fragmentary clouds. Stratus clouds are a branch of stratus clouds, fragmented stratus cloud pieces formed by the splitting of stratus clouds or the lifting of dense fog. Foretells good weather.

3. Translucent stratocumulus clouds. The clouds are thin, gray-white, and arranged neatly. The blue sky can be seen in the gaps. Even if there are no gaps, the edges of the clouds are brighter. It generally predicts no rain.

4. Light-obscuring cumulus clouds. The clouds are thick and dark gray. There are no gaps between the clouds. They are often densely packed into layers and cover the whole sky. There are obvious undulations at the bottom. When it thickens, the weather becomes bad, when it disperses, the weather becomes fine.

5. Cumulus stratocumulus. The clouds vary in size and appear as gray or dark gray strips with cumulus characteristics at the top, formed by the flattening of receding cumulus clouds or cumulonimbus clouds. The weather is slowly getting better.

6. Lenticular stratocumulus clouds. Clouds are flat and often formed directly from heated air rising from the ground in the evening. Fine weather.

7. Castellated stratocumulus clouds. The tops of the row of clouds below are protruding, and the bottoms of the clouds are connected on a horizontal line, resembling a castle in the distance. There may be thunderstorms.

8. Nimbostratus. Low and amorphous, the clouds are evenly layered and can completely cover the sun and moon. They are dark gray or off-white, and are often accompanied by broken rain clouds at the base. Clouds are widely distributed horizontally, often covering the entire sky. The thickness of the cloud layer reaches 4000-5000 meters. Continuous rain and snow.

9. Broken rain clouds. The clouds are low and broken, with variable shapes, gray or dark gray. Appears before and after rainfall. Bad weather.

10. Light cumulus clouds. The individual is small, with clear outline, flat bottom and arc-shaped bulge at the top, shaped like a steamed bun, and its thickness is smaller than its horizontal width. Fine weather.

11. Broken cumulus clouds. The individuals are small, the outline is incomplete, and the shape is changeable. Most of them are white fragments, which are broken or primary cumulus clouds. Fine weather.

12. Cumulus congestus. The individual is tall, with clear outline, flat and dark bottom, overlapping arc-like top, like cauliflower, and its thickness exceeds the horizontal width. If it continues to develop, it will turn into a cumulonimbus cloud. If it collapses, the weather will be fine.

13. Cumulonimbus bald. The cloud tops began to freeze, the arcs overlapping and their outlines blurred, but they had not yet spread out. Continued development indicates thunderstorms.

14. Cumulonimbus mane. The top of the cloud has a white filamentous fiber structure that expands into a horsehair or anvil shape, and the bottom of the cloud is dark and chaotic. Foreshadows thunderstorms.

15. Translucent altostratus clouds. The clouds are thin, uniform in thickness, and gray-white in color. The outlines of the sun and moon are blurred, as if separated by a layer of frosted glass.

16. Light-blocking altostratus clouds. The clouds are thick and gray, with alternating light and dark stripes visible at the bottom. The sun and moon are covered, and their outlines cannot be seen. This is the most difficult cloud to predict weather changes. It can only be determined based on the clouds and atmospheric environment that appear before and after.

17. Translucent altocumulus clouds. The clouds are thin, and the individuals are separated and arranged neatly. The blue sky can be seen in the gaps between the clouds; even if there are no gaps, the thin parts of the clouds are relatively bright. Fine weather.

18. Light-blocking altocumulus clouds. The clouds are thick and densely arranged, with no gaps between the clouds, and the positions of the sun and moon cannot be distinguished. Foreshadows bad weather.

19. Altocumulus lenticularis. The clouds are white, thick in the middle, thin at the edges, well-defined, isolated and scattered, and shaped like pods or lemons. The weather is fine.

20. Fortress-shaped altocumulus clouds. The bottom of the cloud is flat, and the top protrudes into several small cloud towers, resembling a castle from afar. There may be thunderstorms.

21. Floccular altocumulus clouds. The edges of the clouds are broken, much like broken cotton wool. Foreshadows bad weather.

22. Cumulus altocumulus. The clouds vary in size, are gray-white in color, and have slightly cumulus characteristics in appearance. They are formed by the expansion of receding Cumulus Congestus or Cumulonimbus. The weather is getting better.
