What kind of clouds represent what kind of weather?

17 Looking at the weather from the clouds

Liu Yuxi, a poet in the Tang Dynasty, wrote in "Zhi Zhu Ci" that "it rains in the west, sunrise in the east and sunny on the road", which described an interesting weather phenomenon for us. If we want to know the weather today, what should we do? Yes, pick up the phone and dial "12 1". But you know what? In fact, we can be a little weatherman ourselves. Look at the ants on the ground, the spiders in the corner, and the sunset glow on the horizon. Maybe you can predict the future weather. Even some reactions of our bodies are signs that the weather is about to change. Is it interesting? Give it a try!

You can tell the weather by fog. Clouds eat fog and rain, and fog eats clouds and sunny days. Spring fog exposes the dead ghost, and summer fog makes water.

God knows the weather. The stars blink and the rain is not far away. The sunrise is a little red, and no rain is the wind. There is wind in rehmannia and rain in yellow mud. The stars are so thick that they flow all over the street. It's windy in one ear and rainy in two. (Ears, white circles on both sides of the sun)

You can tell the weather by the wind. The east wind sends the wet west wind dry, and the south wind warms the north wind and cools the north wind. Southeast wind during the day, wet cloth at night. The northwest wind opens the sky and locks it in the southeast for a long time. After half a month of drought and rain, there will be no east wind, and the rain will be more fierce in the future. East wind rain, west wind sunny; If the west wind is not clear, it will be cloudy. There are easterly rains in three seasons of the year, especially in summer. The east wind roared day and night, the wind and rain suddenly tightened, the rain was fast and fierce, and the west wind was fine for a long time. Under the four seasons of the east wind, I am afraid that the east wind is not strong enough to see the weather clearly. Ants are in the way, shanghai dawn. Dragonflies fly low, and the rain is calm. Spiders make fine webs and keep them in the shade. Earthworms crawl on the road, and it rains like hemp. Worm aisle, signs of rain. Crows crow at night, and the wind and rain are not far away. The old cow looked up and sniffed the sky. It was raining. The horse's mouth is facing the sky, before the heavy rain. Joint pain, no rain and no wind. The scar itches in the morning and the wind blows at night.

The relationship between different forms of clouds and weather and the relationship between different glorious clouds and weather.

Cloud is

The shape of the "signboard" cloud and the weather are thin → sunny: cirrus, cirrocumulus and altocumulus.

Thick and low → rainy: cirrostratus, stratocumulus, nimbostratus, Cumulonimbus.

Cloud brilliance and weather: halo, glow, rainbow, sunset: the article introduces a lot of content, but because the author adopts the structure of "total-sub-total", the paragraphs are very clear and easy for us to understand. Can you analyze it in detail? Health A: The first paragraph outlines the relationship between different forms of clouds and weather, which plays a leading role in the whole paper.

Reading practice

Read paragraphs 2 ~ 4 of the text and complete the topic.

Experience tells us: thin clouds in the sky; It is 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 the clouds is like a layer of frosted glass. Cirrostratus has changed his surname at this time, and 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.

With the development of high technology, human beings have entered space to observe the weather conditions, and our work and life can be arranged by the information provided by science. So, in your opinion, does the natural observation method of "knowing the sky from the clouds" still make sense? Try to write down your opinion in one paragraph.

You can know the weather by observing clouds, birds and fog. The clouds in the sky are full of gestures; Fog in the sky has various customs. Fog never dresses itself up deliberately, but watching it can give you a unique and interesting aesthetic feeling.

All kinds of customs say that fog is not as spectacular as heavy snow, and there is no lingering customs of light rain. It never dresses itself up deliberately. There is not a flower, a grain, a wisp of fragrance on it, but it permeates the world with its milky white itself. Seeing the scenery in the fog is boring, just like reading a poem with far-reaching artistic conception and profound meaning, which can only be understood, but cannot be expressed. It makes flaws flawless, makes regrets perfect, makes people's thinking gallop freely, and produces unforgettable associations. Wang Zhi, an ancient poet, wrote in "You Dong Lin Shan Shui": "There are long forests and far trees, and there are smoke and flies. Those who gather are happy, those who disperse are different, the whole is like a halberd, and those who are chaotic are like hair. " The Philippines here refers to fog, which means that the fog in the mountains seems to be the joy of long separation; Like the reluctant parting of relatives; Neat as a row of spurge; Chaos is like fluffy hair, with rich and vivid imagination. In fact, fog is a cloud near the ground. This has happened to anyone who has climbed the top of a famous mountain. Seen from the mountain, the mountains are surrounded by white clouds, and the mountains and trees are hidden in them. But when you climb to the top of the mountain, the clouds have disappeared, and you are in a foggy sea, as if you were in a fairyland and want to fly. Fog has different names for different reasons: sunny day, breeze, night and early morning, when the water vapor near the ground is rich and stable or there is inversion, the ground absorbs a lot of solar radiation during the day, and after nightfall, the ground releases heat in the form of long-wave radiation. After the ground cools down, the atmospheric temperature near the ground drops rapidly, so the excess water vapor in the air begins to condense, and the fog formed in this way is called radiation fog; When the moving warm and humid air approaches the cold ground, the fog formed by gradual cooling and condensation is called advection fog; When cold and warm air meet, the fog formed in the front area is called frontal fog. It can be seen that the conditions for fog formation are cooling and humidification. The purpose is to increase the water vapor content, so we can also see an evaporation fog. That is, cold air flows through warm water. If there is a big difference between the air temperature and the water temperature, a large amount of water vapor will evaporate on the water surface, and the cold air near the water surface will condense into fog. At this time, there is often an inversion layer on the fog layer, otherwise convection will spread the fog. Therefore, the range of evaporation fog is small and the intensity is weak. Fog is a very important natural phenomenon, which is closely related to future weather changes. In the long-term productive labor practice, the working people in our country have summarized and accumulated a lot of rich experience in observing foggy days by observing the formation and dissipation of fog. A large number of proverbs are circulated in various places and still have reference value in today's local weather forecast. For example, "there is fog in Huangmei, rocking the boat without asking for directions" is the fog in Huangmei period, which indicates the rainy weather in the future. "You can't see anyone in the fog, so you can wash clothes boldly", "The sky is shrouded in fog, and the sun will come that day", "The morning fog is very heavy, and the weather will last for a long time" and "The fog breaks the stone", all of which indicate that the future will be sunny.

(Excerpted from Sun Huanan's Reading Pioneer)

Fog is closely related to the future weather, so what kind of weather characteristics does fog represent?

The language of expository writing can be divided into two kinds: plain and vivid, and this paper combines these two language styles well. Try to give an example of each one and make a brief analysis.

10, the article says, "Fog is not as spectacular as heavy snow, nor as touching as light rain. It never dresses itself up deliberately. There is not a flower, a grain and a faint scent on it, but it permeates the world with a milky self. " In your life experience, have you ever met someone or something that "just stays on earth" like fog? If so, please write down your opinion.

My experience:

My evaluation:

1 1 "Looking at the scenery in the fog is like reading a poem with profound artistic conception and profound meaning, which is beyond words." Do you feel this way? Please write a paragraph on the topic of "seeing XX in the fog" to express this understandable interest. I believe you can do it!

1? Luán sha yínglínlǐyünzhàolíng 2？ I can't. Because "climate" generally refers to the long-term meteorological conditions in a larger area. "Weather" often refers to various meteorological changes in the atmosphere in a small range and in a short time. Clouds hanging in the sky can identify meteorological conditions in a short time of one day or several days, so it is appropriate and accurate to use "weather". 3? Imitation requires the proper use of metaphor. 4? The relationship between general statements and specific statements. In terms of content, it plays a role in summarizing and prompting the following. 5? "Often" and "often" can not be removed, they explain the relationship between clouds and weather very accurately; If it is removed, it will be too absolute, otherwise it will be inaccurate, because this law is not suitable for special circumstances. This can better reflect the accuracy of explanatory language. 6? Example: (1) There are birds in the mountains, which can be distinguished. (2) Look at the expression and know the heart. 7? Yes First, cultivate their interest in exploring the mysteries of nature; The second is to obtain the philosophical enlightenment of the relationship between natural phenomena; The third is to experience the beauty and interest of nature. 8? It indicates that it will be sunny in the future. 9? Vivid, such as "I don't have a flower on me ... permeating between heaven and earth", vividly writing the characteristics of noble, simple, elegant and pure fog; As plain as "an evaporation fog that can see fog", the formation conditions of evaporation fog are clearly and concisely introduced. 10? You should choose someone or something that is simple and beautiful without deliberately embellishing yourself, and then talk about your own evaluation, which should be based on praise. 1 1? You can not only write about the beautiful scenery at that time, but also the feeling of seeing things in the fog, so as to blend the scene.

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 the clouds is like a layer of frosted 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. When cirrostratus is accompanied by 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.

Cirrostratus is made of ice particles and looks like the lines of white clouds. These are the only clouds that glow around the sun or the moon. Cirrostratus can be divided into cirrostratus and cirrostratus. Cirrostratus, cirrostratus is 5500-8000m above sea level. These clouds are caused by the expansion and cooling of wet air in a wide range of slow oblique movements, so they are related to flowing cyclones and warm fronts and are located at the top of the thunderstorm layer; Sometimes, they are also related to tropical cyclones, because the wind above tropical cyclones blows from the inside to the outside, blowing the cirrostratus away from where they formed. Cirrostratus covers a large area, ranging from several hundred kilometers to several thousand kilometers, with a fairly wide continuous cloud curtain. All of them are composed of ice crystals, and there is a silk thread structure at the bottom of the cloud, which can penetrate the light of the sun and the moon and make the ground objects have shadows. Halos often appear in clouds. If the thickening of cirrostratus decreases and the system develops, it shows that the weather system will affect the stations. Therefore, there is a folk saying that "the sun is dizzy and rainy on the third night, and the moon is dizzy at noon". But if there is no obvious development, even if the cloud cover decreases, the weather will not change obviously in the future.
