Use the words in the text to simplify and understand the weather.

When the snow falls, the cirrus clouds gathered in the sky gradually show thin clouds, as if covered with a white gauze curtain. This cloud is called cirrostratus. Cirrostratus is moving slowly, and the weather will turn cloudy. Then, the clouds are getting lower and thicker, and the clouds, the sun or the moon are separated, just like all other layers of ground glass, hazy. Then cirrostratus will change its name, the phone number of the high-level cloud. There are already clouds at the top, often for hours, and it will rain or snow. Finally, the low-weight clouds become thicker, the sun and the moon are hidden, and the sky is covered with thick dark gray clouds. This cloud is called rain cloud. A rain cloud formed, and endless rain and snow also fell. Before the first arrival.

Thunderstorms in summer see cumulus clouds in the sky. If you hit the high Yunshan quickly in the form of cumulus clouds, the peaks will compete and the zenith will be crowned, and it will become a cumulonimbus cloud. The bottom of the long high cumulonimbus clouds gradually turns black, and the Yunfeng gradually blurs. Soon, the whole Yunshan collapsed. Suddenly, the luster of thunder and lightning will collapse, and soon it will rain, sometimes even bring hail or tornado.

We can respect the phenomenon of clouds and show the weather conditions. Around the sun and the moon, sometimes beautiful and colorful irises appear, with red inner layer and purple outer layer. This aperture is called halo. Halos and auras often produce cirrostratus, followed by large stratocumulus clouds and rainy cirrostratus, which are signs of storms. Therefore, there is a saying that "the night rain is dizzy and the afternoon wind is dizzy". Cirrostratus appears, accompanied by dizzy instructions, and the weather will get worse. It is called the "China" smaller than the faint halo. The color of ultraviolet light is arranged in red, which is just the opposite of halo. Rihua and Yuehua are mostly produced at the edge of some cumulus clouds. The trend of Chinese rings from scratch, from small to large, and sunny weather. From the big to the small China ring, the weather may become rainy. In summer, when the sun passes through clouds and curtains, it often hangs a colorful arc, which is the rainbow. People often say, "There are dragons in the east, rainbows in the west." This means that in the eastern rainbow, it thunders and it doesn't rain; The rainbow is in the west and there will be heavy rain. Another kind of cloud often appears in the early morning or evening. The clear blue sky dyed the clouds red, and the clouds were called Xia. The morning glow is in the west, indicating that the air inlet has given us rainy weather; The sunset in the east shows that the weather has been good in recent days. Therefore, there is a proverb that "the morning glow does not go, and the sunset glow travels thousands of miles".

Cloud computing can help us identify sunny and rainy days and predict weather changes, which is of great significance in industrial and agricultural production. We should learn to know the weather from clouds, learn from people's experience with an open mind, observe the changes of clouds, and master the law of repeated observation. But the weather is very complicated. After seeing certain limitations, the weather knowledge of cloud computing. In order to accurately grasp the weather changes, we have to rely on the weather forecast.
