How to use clouds to identify the weather?

Look at the clouds to know the weather, spring, summer, autumn and winter, rain and snow, changeable and colorful. Weather is closely related to human life. The change of weather has its own signs. Now, please look at the sky, at the clouds, at the words of nature, and at the "signboard" of the weather. How to interpret it? The clouds in the sky are really varied and changeable. Some are like feathers, floating gently in the air; Some are like fish scales, neatly arranged one by one; Some come and go like sheep; Some are like a big quilt, covering the sky tightly; Others are like mountains, rivers, lions and galloping horses ... sometimes they decorate the sky beautifully, and sometimes they cast a shadow over it. Just now, it was white clouds and the sun was shining; In a blink of an eye, it was cloudy and it rained cats and dogs. Clouds are like the "signboard" of weather: what kind of weather will appear when there are clouds hanging in the sky. Experience tells us that thin clouds in the sky are often a symbol of sunny weather; Those low and thick clouds are usually signs of rain and snow. The lightest and tallest clouds are called cirrus clouds. This kind of cloud is very thin, through which sunlight can shine on the ground, and the light and shadow of houses and trees are still very clear. Cirrus clouds are constantly floating, sometimes like a white feather, sometimes like a white silk thread. If cirrus clouds are arranged in a row in the air, like fish scale waves caused by a breeze blowing over the water, it becomes cirrus clouds. Cirrus clouds and cirrocumulus are very high, where there is little water, which generally does not bring rain and snow. There is also a kind of white clouds like cotton balls, called cumulus clouds. They are often scattered in the sky about two kilometers, reflecting the bright sunshine, and the clouds are surrounded by golden brilliance. Cumulus clouds appear in the morning, most in the afternoon, and gradually dissipate in the evening. On sunny days, we occasionally see a kind of cumulus. Altocumulus clouds are groups of oblate clouds, which are arranged in a balanced way, with a blue sky in the middle, which looks like snow-white sheep on the grassland from a distance. Cirrus, cirrocumulus, Cumulus and Cumulus are all beautiful. When the continuous rain and snow came, cirrus clouds were gathering, and a thin layer of clouds gradually appeared in the sky, as if covered with a white silk curtain. This cloud is called cirrostratus. Cirrostratus is advancing slowly, and the weather will turn cloudy. Then, the clouds are getting lower and thicker. Looking at the sun or the moon through clouds is like looking through a layer of ground glass. At this point, the scroll tower has been renamed. It's time to call it a high-level cloud. There are high clouds, and it often rains or snows within a few hours. Finally, the clouds are getting lower and thicker, the sun and the moon are hidden, and the sky is covered with dark gray clouds. This cloud is called nimbostratus. As soon as nimbostratus was formed, continuous rain and snow came. In summer, before a thunderstorm, cumulus clouds are first seen in the sky. Cumulonimbus clouds become cumulonimbus clouds if they swell up quickly to form tall Yunshan, and the peaks compete with each other and go straight to the zenith. The cumulonimbus cloud grows higher and higher, the cloud bottom gradually turns black, and the Yunfeng gradually blurs. Soon, the whole Yunshan collapsed and dark clouds filled the sky. In an instant, thunder rumbled and thundered, and then it rained heavily, sometimes bringing hail or tornadoes. We can also infer the weather from the brilliant phenomena on the clouds. Around the sun and the moon, sometimes beautiful colored apertures appear, the inner layer is red and the outer layer is purple. This aperture is called halo. Solar and lunar halos often appear on the cirrostratus, and the high-rise clouds behind cirrostratus and nimbostratus are signs of heavy rain. So there is a saying that the sun is dizzy in the middle of the night and the moon is dizzy at noon. It means that when cirrostratus appears, with dizziness, the weather will get worse. There is also a colored halo smaller than the halo, called "Hua". The arrangement of colors is purple and red, just the opposite of halo. Rihua and Yuehua are mostly produced at the edge of cumulus clouds. From small to large in central China, the weather tends to be fine. The central region of China is getting smaller from big to small, and the weather may turn rainy. In summer, after the rain clears, a colorful arc is often hung on the cloud curtain opposite the sun. This is a rainbow. People often say: "The east rainbow thunders and the west rainbow rains." If the rainbow is in the east, it will thunder and not rain; The rainbow is in the west and there will be heavy rain. There is also a cloud color, which often appears in the early morning or evening. The sun shone all over the sky and dyed the clouds red. This cloud is called Xia Xia. The morning glow is in the west, indicating that rainy weather is attacking us; The sunset glow in the east means that the weather has been fine in recent days. Therefore, there is a proverb "Don't go out at sunrise, but go to Wan Li Road at sunset". Clouds can help us identify sunny and rainy days and predict weather changes, which is of great significance to industrial and agricultural production. If you want to learn to know the weather by observing the clouds, you must learn from experienced people with an open mind, pay attention to the changes of the clouds, and master the rules through repeated observation. However, the weather changes are extremely complicated, and there is a certain limit to understanding the weather from the clouds. In order to accurately grasp the weather changes, we have to rely on the weather forecast.
