Seeing the original text of weather from the clouds

Lead: "Seeing the weather through clouds" has been selected as the first volume of the ninth grade Chinese textbook of the new curriculum standard for nine-year compulsory education, with the special topic of "meteorological phenology". Let me read the original text of the cloudy weather for you, hoping it will help you!

Seeing the original text of weather from the clouds

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 line up in the air, just like the 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 flat spherical clouds arranged evenly, with a blue sky in the middle, which looks like 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. If the cumulonimbus cloud rises rapidly, forming a high Yunshan, competing with each other and heading straight for the zenith, it will become a cumulonimbus cloud. The cumulonimbus cloud grows taller and taller, the cloud bottom gradually turns black and the clouds gradually blur. Soon, the whole Yunshan collapsed and dark clouds filled the sky. In an instant, thunder rumbles, lightning flashes and thunder rumbles, and soon it will pour with rain, and sometimes it will bring hail or tornado.

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.

Analysis on the article "Seeing the weather from the clouds"

This is a popular science article. The author introduces the relationship between clouds and weather from two aspects with vivid language: the relationship between different forms of clouds and weather; The relationship between different glorious clouds and the weather.

The article first talks about the relationship between different forms of clouds and weather. Paragraph 1 is an overview with a unique language. First of all, I always say: the clouds in the sky are really ever-changing. Next, the author uses metaphor and parallelism to describe the myriad poses of the cloud very vividly, which can stimulate readers' imagination. To learn this language, teachers should familiarize students with it, appreciate the beauty of the language, imagine the wonderful changes in the blue sky and white clouds, and even let students imitate writing.

The following four paragraphs specifically introduce the relationship between cloud morphology and weather. The second paragraph is the outline of the next three paragraphs: thin clouds are often a symbol of sunny weather; Low and thick clouds are often a sign of rain and snow. The teacher reminds the students to think: Why is it often used as a restrictive word here? Can you do without it? The last three paragraphs follow this outline. This is the main idea of the article. The teacher should guide the students to clarify this idea. Clear your mind and you won't be blind when you read the article.

Specific to a paragraph, there are also ideas. The third segment corresponds to the thin cloud in the second segment. How many kinds of thin clouds are there? What are the characteristics of thin clouds? Thin clouds are divided into cirrus, cirrocumulus and cumulus. They have their own characteristics and similarities. Teachers should guide students to find out their own characteristics and similarities. This paragraph is divided into four layers, which is very clear. Teachers can let students write by themselves. The author's clear thinking is expressed by classifying other methods. There are four kinds of thin clouds, which are introduced in an orderly way, and are worth learning and learning from.

Paragraphs 4 and 5 correspond to the heavy rain and snow in paragraph 2, and the writing ideas are the same as those in the above paragraphs. Starting from paragraph 6, the article turns to another meaning, that is, the relationship between cloud luster and weather. It should be said that the brilliance of the clouds is covered by the clouds in the sky at 1, which is really changeable. The difference is that paragraphs 3, 4 and 5 are explained from the perspective of the relationship between cloud morphology and weather, while paragraph 6 is changed from the perspective of the relationship between cloud brilliance and weather. Teachers should guide students to see the change of interpretation angle and sum up their writing experience: they should be good at explaining things from different angles. According to the different brilliance of clouds, the author divides clouds into four types: halo, glow, rainbow and chardonnay. The author also introduces the difference between them, which is a comparative explanation. The author also quoted a proverb, explaining that it has been tested by people's practice and is a summary of life experience. The level of this paragraph is also very clear. This can inspire students to sum up the characteristics of clear paper writing level.
