1. Children's meteorological knowledge

Meteorological knowledge of children 1. Know little about meteorology

1) Look at the proverb 1, the morning clouds disperse and the dog dies at noon. 2. Be afraid of the south cloud early and the north cloud late. Clouds will rise from the southeast, but the rain will not last. At sunrise, the red clouds will rise, so it is recommended not to go far away. When the red clouds rise at sunset, it will be sunny. 5. Dark clouds will be high and there will be rain tomorrow; Dark clouds are low after sunset, and it rains at night. 6. Oolong hits the dam, and it rains if it is not cloudy. 7. The clouds are in the east, and the rain is not fierce; The clouds are in the south and the river rises. 8. There are clouds hanging in the sky and rain dripping on the ground; Broom clouds in the sky, three days of rain; Cotton clouds in the morning will rain in the afternoon; Tower clouds in the sky, thunder and rain in the ground. 9. Northwest Huang Yun, hail ahead. 10, fish scales in the sky, no rain and wind. 1 1, there is no good goods in the northwest, either wind disaster or hail 1 1, dark clouds are the limelight, and white clouds are the omen of rain. Clouds get married, and the rain is more fierce. 13. Clouds cover the fog in the morning, and there is no rain and wind. 14. Clouds eat under fog, and fog eats clear clouds. 15. Clouds are heading east and gusts are blowing; The clouds are heading west, covered with hemp fiber. 16, sunny in the morning and sunny at night. 17, there are pod clouds in the sky, and it will rain soon; There is an anvil cloud in the sky, and it will rain heavily soon. 18, dark clouds see the sun, and it rains in the middle of the night; Dark clouds have white feet, and there must be heavy rain; The clouds don't go away, and it will rain soon. 19, dark clouds began to smoke, and hail was on the same day. (2) Observing the wind and measuring the sky proverb 1, under the easterly winds of the four seasons, I am afraid that the easterly winds will not blow much. 2. It will rain continuously in spring and intermittently in summer; The east wind doesn't match in autumn, and it snows for a long time in winter. Open the door to the wind and close the door to the rain. The east wind will rain and clear up, but it won't. 5. The south wind blows to the end, and the north wind reciprocates. 6. The east wind is urgent, the rain hits the wall, the south wind is hard at the waist, and the north wind is pointed at the head. 7. The east wind does not rain in the drought, the west wind does not clear up after the rain, and the southwest wind does not fall for three days. In September and May, there will be heavy rain in the south wind. In June, the bottom of the south wind will be very dry. 10, and the southerly wind will be cloudy if it doesn't rain for three days. 1 1, the east wind will be wet, the west wind will be dry, the north wind will be cold and the south wind will be warm. 12, no rain, cloudy against the wind. The south wind is afraid of sunset, and the north wind is afraid of dawn. 16, fog dew in the south wind, frost in the north wind. 17, the wind blows every night, and the rain and snow don't meet; It will be cloudy if the south wind exceeds level 3. 18, there will be sails in the wind, and the rain will clear up. 19, the east wind rang before noon. 20, the east wind is strong after the rain, and it will rain again tomorrow. 2 1, hail comes and goes with the wind, and the headwind will turn around. It will be windy in spring. It rained heavily when lightning struck the clouds. The thunderstorm is not fierce, and the pit is full of muffled thunder. 4. The sudden thunder quickly dispersed, but the muffled thunder was hard to clear. Thunder is like grinding, and the wind is mixed with hail. 6. Spring thunder 10 is cloudy and winter thunder 10 is cold. 7. The sky flashes in the east, the rain flashes in the west, the fire door opens in the south, and it flashes all night in the north. 8. The southeast flash is clear, and the northwest flash is clear. The weather will clear up soon. The bird landed on the boat, and the rainy day passed. 4. Magpies crow, and it is sunny to go out. Crickets are chirping in the house and crops are blistered. 6. The weather will get worse because of mosquito bites. 7. Dragonflies go round and round, and it will rain a day before. 8. Bees are busy picking flowers, and it will rain soon. 9. Back pain and itchy scars. It rained for three or five days. 12, swallows fly low, ants move, fish come to the water to catch their breath, and heavy rain is coming soon. 13, cats wash their faces, frogs call it rain. 14, mantis flying around, with showers. Spiders weave webs, and it will clear up after a heavy rain. 46638.6886868666 1

2. Know little about meteorology

1. Cool down

According to statistics, the month with the strongest cold air in China is 1 1. From June to February in 5438, the average temperature in most parts of the north was between–5℃ and–20℃, and frost sometimes appeared after the strong cold air in the south.

2. heavy snow

Strong cold air can often form large-scale snowfall or local blizzard. Snowfall has many benefits, especially for relieving winter drought and freezing farm diseases and insect pests. However, the snowy road is slippery and icy, which easily leads to civil aviation flight delays, road traffic accidents and lane congestion; In some areas, snow storms and road closures will also pose a threat to the safety of people and animals in pastoral areas.

3. freezing rain

Freezing rain is snow falling from the upper cold layer, sometimes it melts into rain in the middle layer, and becomes supercooled water with raindrops at a temperature below 0℃ in the lower cold layer. The supercooled water drops fall from the air, reach the ground and touch anything on the ground, and immediately freeze to form freezing rain. When freezing rain occurs, uneven ice shells appear on the ground and objects, which will have a great impact on traffic, electricity and communication, and will also cause damage to fruit trees.

4. Frost

Rime is the milky white ice crystal precipitation formed on objects by direct condensation of water vapor in the air at low temperature or direct freezing of supercooled water droplets. There are many foggy days in winter in China: Heilongjiang, Jilin, northern Xinjiang and northern Shaanxi. Rime is a kind of natural beauty that people generally appreciate, but sometimes it will become a natural disaster, which will seriously break wires and trees and affect traffic, power supply and communication.

5. Heavy rain

The formation process of rainstorm is quite complicated. Generally speaking, sufficient and continuous water vapor, strong and lasting upward movement of airflow and instability of atmospheric structure are the main physical conditions for heavy rain.

The favorable combination of various scales of weather system and underlying surface, especially topography, can produce heavy rain. The main weather systems that cause large-scale rainstorm in China are fronts, cyclones, shear lines, eddies, troughs, typhoons, easterly waves and intertropical convergence zone. In addition, thermal thunderstorms will also cause short-term and small-scale heavy rains in arid and semi-arid areas.

Extended data:

1. The dew in the morning is usually clear.

Why is it usually sunny when there is dew? This is because on a clear and cloudless night, the ground dissipates heat quickly, the field temperature drops rapidly, and the tolerance for water vapor in the air weakens, so that water vapor condenses on grass leaves and stones one after another. On a cloudy night, the ground seems to be covered with a big quilt, so the heat is not easy to dissipate, the temperature does not drop, and the water vapor stored in the cold is not easy to condense into dew.

There is always a rainbow after the rain.

In the air after a heavy rain, there are many small water droplets floating in the air. They are like prisms hanging in the air. When sunlight passes through them, it is first decomposed into seven bands: red, orange, yellow, green, cyan, blue and purple, and then reflected back. At this time, if someone stands between the "rain curtain" formed by the sun and raindrops, they will see colorful rainbows.

It usually snows in winter.

Winter is coming, why does it snow? This is because the temperature is low in winter, the ground temperature is below zero, and the temperature of high-altitude clouds is even lower. Water vapor in the cloud condenses directly into small ice crystals and snowflakes. When these snowflakes increase to a certain extent, the airflow can't hold, and falling from the clouds to the ground means snow. If there is a strong updraft, the air temperature will be higher, just like a big hand holding snowflakes. Snowflakes grow up in the clouds for a longer time and fall more.

See the lightning before you hear the thunder

The reason why you see lightning first and then hear thunder is because in the air, light travels fast and can reach the ground soon, while sound travels slowly in the air and will reach the earth in a short time. So you will hear lightning first, and then thunder. In fact, lightning and thunder appear at the same time.

The reason why the time to reach the ground is so different is that the speed of light is 3,000,000 kilometers per second, while sound can only travel 0.34 kilometers in the air for 65,438+0 seconds. The speed of sound is only one-ninth of the speed of light.

Lightning is long and short, loud and quiet. You can roughly judge the height from the clouds to the ground according to the time when the sound reaches the ground. It doesn't take much time for light to reach the ground, which can be considered as 0. The interval between seeing lightning and hearing thunder is how many seconds times 340 meters, which is the distance from lightning to you.

Lightning will reflect when it meets clouds or tall buildings, so it usually takes some time for lightning to disappear after lightning.

3. Pupils' knowledge of thunderstorm prevention

With the arrival of summer, there are more and more thunderstorms. In order to strengthen the safety management of schools in summer, let primary school students fully understand the harm of lightning and learn the knowledge of lightning protection, I will tell you some knowledge about lightning.

"When encountering thunderstorm weather, teachers and students outdoors should immediately enter the building and close the doors and windows. Don't take shelter from the rain under the big tree, don't use metal umbrellas, and try not to ride bicycles; Stay away from balconies, metal railings, metal security nets, wires and other conductors and external walls of buildings, do not use faucets and showers, try not to use telephones, and turn off electrical equipment such as televisions, computers and stereos. If there is no place to hide in the open field when there is lightning, you should try to find a low and concave place (such as a pit) to hide, or immediately squat down, put your feet together, put your arms around your knees, try to bow your head, and don't stand on the playground when it thunders.

4. How to guide children to understand the safety tips in different weather?

Activity objectives:

1, understand the common sense of traffic safety related to your life, and cultivate children's awareness of obeying traffic rules.

2. Enhance safety awareness in summer to prevent drowning and food poisoning.

Activity preparation:

Some traffic signs, pictures of drowning prevention and moldy food.

Activity process

Introduced a conversation.

1, traffic safety: (1). Q: The children will have their summer vacation soon. We may cross the road every day when we go out to play, so what should we pay attention to when crossing the road? (Children answer questions according to their life experience) (2) Teacher: Let's see what happened on the road. (Guide the children to look at the picture: At the crossroads, cars and bicycles are constantly flowing. A child crossed the road and walked on the zebra crossing without looking at the traffic lights, and was almost knocked down by a car. Teacher's question: What did you see just now? Is this child doing the right thing? Why? Show pictures of traffic lights and zebra crossings to educate children to master traffic knowledge. Children's Song: Children, when crossing the road, you must watch the traffic lights, stop at the red light, go at the green light and stop at the yellow light. Teacher's warm reminder: zebra crossing is a crosswalk. Children must take the zebra crossing when crossing the road, but don't walk around.

The teacher concluded: children, when crossing the road, you must look at the traffic lights, and you can get home safely by crossing the zebra crossing.

2, drowning prevention: Teacher: What season is it now, children? Yes, it's summer and it's getting very hot. What should you do if you feel hot? But this year, several children quietly took a bath in the pond because of the hot weather. Do you want to know what happened when they took a shower? I tell you, several children drowned in the river before, and they will never see their parents again. They are so poor, the teacher is very sad, and so are their parents.

Teacher: Little friend, how can we prevent ourselves from drowning? I think we should do the following:

(1) Educate children that it is forbidden to play and swim in rivers, ponds and uncovered wells during summer vacation. You can't go fishing, swimming or playing with water by the pond alone or in groups.

(2) Educate children never to play with water or swim in the river during holidays.

(3) We are children in kindergarten, and many children can't swim. If we find a child accidentally falling into a river, reservoir, pond, well, etc. We can't go into the water to save ourselves. We should ask adults for help or call "1 10".

The teacher summed up: People only have one life, so we should protect ourselves. You can't go to the river, the seaside or the well alone. You must be accompanied by an adult. In case of danger, shout for help!

Second, food safety in life.

1, what problems should be paid attention to during the diet?

2. Encourage children to speak their minds boldly.

3. Play the pictures and let the children talk about their ideas one by one.

The teacher concluded: Be careful not to eat expired and rotten food. Toxic drugs should be kept in a safe place, and we shouldn't eat food fried repeatedly.

Fourth, I know a little safety knowledge.

1. In addition to food, we should also pay attention to safety in summer vacation and in many places in daily life. What safety tips do you know?

2. Guide children to boldly say what they know about safety.

Teacher's summary: In case of danger, you should keep calm, learn to save yourself, protect yourself, and try your best to keep asking for help, such as 1 19 fire alarm,10 alarm, 120 first aid, 122 traffic accident alarm, etc.

Sixth, cherish life and put safety first.

1, life is beautiful, life is colorful, and the premise of all this is safety. Therefore, we must strengthen safety awareness, strive to enhance self-prevention ability, and achieve "cherish life and safety first".

2. Teacher's summary:

There is only one life, and happiness is in your hands. I hope that through this safety education class, children can learn to cherish life and form a good habit of consciously observing the safety principle of drowning prevention.

5. Essay on Small Weather Station

In spring, the face changes three times a day, sometimes sunny, sometimes rainy, sometimes warm and sometimes cold. From this, I found that children are more and more sensitive to weather changes. They are willing to pay attention to weather changes and are interested in observing natural phenomena such as wind, rain and clouds. At the same time, there is a weather corner in our classroom. The children take turns to record the weather forecast learned from different channels every day, so chatting, watching the weather and discussing the weather have become small topics for me and my children after dinner. "I saw on TV that it would rain today." "Today, my mother sent a message on her mobile phone saying 16-25 degrees." ……

In addition, in this spring season, there are all kinds of small animals in the natural corner of our classroom. I found that even children in large classes have an inseparable love for small animals. In the corner of nature, I often see some children staring at small animals; Some children are playing with small animals; Other children are talking to small animals. When the weather changes, the abnormal behavior of small animals arouses children's curiosity and concern. So I thought why not combine the weather with animals in nature, so on the basis of children's experience and changeable weather, I did this activity after children's lunch. "Look! What is the weather like today? " The question thrown at the beginning caused the children to talk about the weather: "It's raining outside today!" "It's raining heavily today!" "The drizzling spring rain outside is accompanying our children to class!" Then "Who knows what the weather will be like tomorrow?" Where did you know that? "Another question about the weather was thrown at the children, which triggered another discussion among the children. Yu Tianyu said, "I saw on TV that it will be cloudy tomorrow. Zhu said: "I know from my mobile phone that the highest temperature tomorrow is 17 degrees and the lowest temperature is 27 degrees." "So TV, newspapers, telephones, mobile phones, and computers blurted out various ways to understand the weather from the children's mouths, and at the same time, the PPT that was clicked intuitively listed the various answers listed by the children." Hey! It turns out that the weather forecast can be learned in so many places. Then how did these weather forecasts come from? Ok, let's walk into the weather station and see the work of meteorological scientists! "The video science and education film combining sound, image and image brought the children into the real weather station, and the shutter box measured the temperature; Wind ball measures wind direction; The anemometer measures the size of the wind; Rainfall measured by weather radar; Fengyun satellite takes meteorological cloud pictures. Professional terminology and real pictures completely attracted children's attention, and children were fascinated. For children, a new field opens another skylight for children's knowledge. " It turns out that meteorological scientists have to do so much work to predict the weather for us based on the information such as temperature, humidity, wind direction, wind force and satellite cloud pictures measured by various instruments. Their work is really amazing. The busy work, novel instruments and advanced technology in the meteorological workstation immediately aroused the children's voices. This documentary not only gives children the knowledge concept of measuring the weather, but also gives them an emotional impact. They saw the work and hardships of scientists behind the small weather forecast and heard the contribution of the rapid development of science and technology to our weather forecast. In addition to these clever and capable meteorologists, there are also many meteorologists in nature, and small animals are one of them. "From the natural transition from a weatherman to an animal meteorologist, the little things that opened the curtain followed." How do they forecast the weather? "The first question is for children, Dragonflies Fly Low, Ants Climb Trees and Fish Noodles. Children fully mobilize and use their existing wisdom to describe their existing knowledge and experience. In this round of challenges, there are children's songs and fierce collisions between children.

So how do these small animals predict the weather in the face of controversy in the spark of collision? Why not let the children find the answer by themselves through different channels? Then, another challenge began. "Well, first discuss with your friends to choose a small animal you want to know most, take off its signboard, then find out the weather forecast information of this small animal according to the signboard, and finally discuss how to tell you in your favorite and best way." After making the request, all the children accepted the challenge with confidence. Take the reminder card and follow the arrow to find the answer, then call the hotline for help, search and browse books, listen to the tape, watch the computer, cooperate and share, and rely on the power of cooperation to help each group of children get the weather forecast information of small animals from different ways. Then, the children began to get together in twos and threes to discuss the expressions they were good at. They are eager to convey the answers and information they have found in different ways, such as nursery rhymes, paintings, situational performances, and three-dimensional teaching AIDS demonstrations. Each group began to get busy, from selection to discussion, from lines to actions, from conception to stereotypes, and everything was completely handed over to the children through cooperation and creation.

6. Little is known about life meteorology

Meteorology is a subject that takes the atmosphere as the research object, explains the characteristics of large-scale agricultural meteorological gases from both qualitative and quantitative aspects, and focuses on the weather situation and changing law of the atmosphere and weather forecast.

Meteorology is a branch of atmospheric science. The science that studies the physical phenomena and processes in the atmosphere and their changing laws.

The research field of meteorology is very wide, and the research methods are also very different. Meteorology is divided into many branches: atmospheric physics, meteorology, dynamic meteorology, climatology and so on.

With the development of production, the application of meteorology is increasingly extensive, and applied disciplines such as marine meteorology, aviation meteorology, agricultural meteorology, forest meteorology and pollution meteorology have appeared one after another. With the application of modern science and technology in the field of meteorology, new branches have emerged, such as radar meteorology, satellite meteorology, cosmic meteorology and so on.

Meteorology is an applied science closely related to production and life, involving many disciplines. Edit this research task 1 to observe and study various atmospheric phenomena, the interaction between the atmosphere and the underlying surface and the meteorological effects caused by human activities.

2. Explain these phenomena, functions and influences systematically and scientifically, and clarify their occurrence and evolution laws. 3. Analyze, diagnose and predict the past, present and future weather according to the known laws.

Climate serves the national economy and people's daily life. 4. The weather process and artificial climate environment explored and simulated according to theory and practice provide scientific basis for artificially influencing weather and climate.

Editing this history The first person to establish meteorology was the ancient Greek philosopher Aristotle. He described and explained the weather phenomena such as wind, clouds, rain, snow, thunder and hail for the first time in the world's earliest meteorological book, Dynamic Meteorology, and the monograph "Meteorological Exchange Theory".

Until 18- 19 century, due to the development of physics and chemistry and the continuous invention of measuring instruments such as pressure, temperature, humidity and wind, atmospheric science research entered the stage of quantitative analysis from simple description. 1820, Budrin, a German, drew the first surface weather map, which initiated modern weather analysis and forecasting methods.

1835, French Coriolis put forward the concept of wind deflection; 1857, Dutch C. H. D. Buys Ballot put forward the relationship between wind and air pressure, and their concepts became the basis of atmospheric dynamics and weather analysis. Around 1920, Pierre Knies and his son put forward a set of theories called "polar front theory" to explain the weather changes in mid-latitude areas.

It has been more than 70 years since 1920s was published, but it is still the main theoretical basis for today's weather forecast, and it also lays a theoretical foundation for analyzing and forecasting the weather in the next 1-2 days. 1930 s, the extensive use of radiosondes really began the atmospheric science research in three-dimensional space.

According to the high-altitude weather map drawn by a large number of detection data, the atmospheric long wave was found. 1939, Rossby proposed long-wave dynamics, and his theory also made great contributions to weather forecasting.

1From 1950s to 1960s, with the application of computer, weather radar, satellite and remote sensing technology, all kinds of atmospheric phenomena, from atmospheric circulation to raindrop formation, can be expressed in physical and chemical mathematical forms, thus making atmospheric science develop by leaps and bounds. The embryonic stage of this editorial development mainly refers to the long period before the middle of16th century. The characteristic of this period is that due to the needs of military meteorology and human life and production, some sporadic and local meteorological observations have appeared, some perceptual knowledge and experience have been accumulated, and some weather phenomena have been explained.

During this period, China has made many achievements in this field and is in the leading ranks in the world. As early as 3000 years ago, there were written records about wind, clouds, rain, snow, rainbows, clouds, tornadoes and thunderstorms. In Jia Shu of Yin Dynasty, people often ask about the weather in the next ten days (called "insolence") and record the actual situation for verification.

During the Spring and Autumn Period and the Warring States Period, according to the observation records of wind, clouds and phenology, 24 solar terms can be determined, which is of great significance to guiding the agricultural production season in the Yellow River basin and has been used until modern times. During the Qin and Han Dynasties, books on phenology also appeared, such as Lu's Chunqiu, Huainanzi and Book of Rites, which are the earliest phenological documents in the world.

Meteorological observation instrument is also the earliest invention of China. In the Western Han Dynasty (BC 104), three kinds of anemometers, Dai, Tong Feng and Xiang Bird, were popular, but in the Tang Dynasty, Xiang Feng Bird was used in fixed places, and the army used anemometers made of chicken feathers.

It was not until the 20th century that Europe recorded the use of migratory birds to measure the wind. In the Western Han Dynasty, the moisture absorption characteristics of feathers, charcoal and other things were also used to measure the air humidity.

In the Song Dynasty, a monk Zanning (A.D. 10 century) used a soil carbon hygrometer to forecast sunny and rainy days. The record of precipitation is also the earliest in China. According to the records of the later Han Dynasty, every county and state under its jurisdiction reported the rain to the imperial court every year from beginning of spring to beginning of autumn. Since then, all previous dynasties have attached great importance to the rain in various places.

Therefore, China has abundant rainfall, many floods and droughts, and the longest history. Due to the needs of production and life, human beings urgently need to predict the future weather changes, and have accumulated a lot of experience in long-term observation practice.

These experiences are expressed in short verse for easy memory and use. This is a weather proverb. The weather proverbs in China are extremely rich, except for some feudal superstitions, which are mostly the crystallization of the working people's experience in observing the sky.

Huang Zifa's Xiang Colleen Chan in Tang Dynasty, Tian Wu Jia Xing edited by Lou Yuanli at the end of Yuan Dynasty and the beginning of Ming Dynasty, and Zhan Hou by Xu Guangqi at the end of Ming Dynasty are all works summarizing people's experience in weather forecasting. In foreign countries, meteorology sprouted very early. In the 4th century BC, the great Greek philosopher Aristotle wrote a book called Meteorology (about 350 BC), which comprehensively discussed water, air and earthquakes, and made an appropriate explanation for atmospheric phenomena.

Nowadays, the foreign names of meteorology are all evolved from Aristotle's original name. In short, in the embryonic period of meteorology, China and Greece had contact. At this time, from the disciplinary nature, meteorology and astronomy are mixed together, which can be said to have the nature of astrology.

The initial stage of development includes1mid-6th century to1end of 9th century. At this time, due to Europe.
