Write a composition with thunder

1. Write a composition entitled "Why does it thunder?" There is air as an insulator between the two negative charges, and the temperature is obviously higher. On 14, the highest temperature reached 22. 1℃, the highest in the same period in history, and it rained cats and dogs in an instant.

Since the middle of 5438+ 10, the warm and humid air flow has been extremely strong. I understand the reason of thunder in these hot summers. Although there is a voltage difference between the two negative charges, it is difficult to understand.

Thunderstorm clouds generally have two conditions, sufficient water vapor and strong convection. In winter, there is thunder and lightning.

Well, sometimes it will be cloudy. Not only does it thunder in summer, why does it thunder in summer? The reason is this: when the air is extremely unstable, it is easy to have strong upward convection and form towering cumulonimbus clouds. The cloud is full of water vapor running up and down, which will generate static electricity and cannot be discharged.

If the voltage difference between two negative charges is large enough to break through the air of the insulator. But sometimes when the temperature is high in winter, it will form thunderstorm clouds, leading to lightning and rain and snow.

Convection is particularly strong and the ground is negatively charged. Because the air is cold and dry, the solar radiation is weak and there is little lightning, it is not easy to form convection in the air. On June 5438+07, when the strong cold air in the north moved south, it was only lightning, and the explosion made a loud noise, not thunder. When they met, it not only snowed, but also thundered. The upper end of the cloud will produce positive charge, while the lower end of the cloud will produce negative charge, which may also form hail. This will produce the so-called "thunder in winter" weather phenomenon, which will make the air instantly expand and explode, glow, and sometimes thunder in winter.

According to experts' analysis, lightning is a discharge phenomenon in thunderstorm clouds.

2. Writing about Thunder 1 is nothing. Then, the wind blew violently with heavy rain, as if the calm sea was blown by the wind, turning up huge waves and raindrops beating on the glass windows of thousands of families. The original blue transparent windows have also been "watered" by huge waves, and countless dots are like peas of different sizes, with countless white faces.

It thundered suddenly in the storm. Lightning and thunder, the wind roared, and there were few pedestrians on the road. Only adults walk home with umbrellas.

Lightning flashed across the sky, shuttled in front of the window, and then there was a loud thunder above. Thunder is sometimes like a pile of explosive gunpowder, which is big enough to cover your ears; Sometimes like firecrackers, loud and clear; Sometimes 10 million drops of water fall on the floor, just like the sound of music ... 3. Suddenly, dark clouds come to make trouble, covering the white clouds and making the sky gloomy, as if it were going to be crushed.

What is this? I looked up and it was raining! The light rain hit me, so cool, so comfortable and so happy, because it finally rained. I wanted to sleep on the spot, and suddenly there was a "crash" and a dazzling flash of lightning appeared, "Boom!" Deafening thunder and lightning returned to the world.

Suddenly, a flash of lightning jumped out of the clouds and exploded in the sky, blinding us like a military flash bomb. I was so scared that I quickly covered my ears. As I expected, in a few seconds, tripterygium wilfordii boomed.

Suddenly there was a flash of lightning, then a burst of thunder, a flash of lightning, a burst of ... I went to throw garbage, and a dazzling flash of lightning hit me, followed by a huge thunder, which startled me and made my heart thump. It rained heavily during the break. The stairs on the fourth floor are constantly flowing, and the small balcony next to the classroom is constantly "supplying water" to the stairs.

6. A sudden thunder startled me. I hurried to the window and put my head on the window so that I could see the scenery clearly.

The sky was sunny just now, but now it is covered with layers of dark clouds, as if someone had built a hard and black dam there with air. 7. The rain is getting heavier and heavier, and there is not a crack in the air, which is enough to make a small hut collapse.

I stood at the window, watching the magic rain, and thought: It's raining too hard. If any family forgets to collect clothes, it will be miserable! 8. I don't know when the clear sky darkened. Standing on the balcony, the cool breeze blows gently. The leaves outside the window, the curtains inside the window, and the long hair of the little girl on the roadside all danced with the wind, as if welcoming distinguished guests.

I also like this feeling, so I moved a small stool and waited quietly for the storm to come. Finally, the rain came back to your home and thought of us with lightning speed.

I looked up and saw the dense raindrops, just like the troubles in my heart, all fell to the ground. 9. There is a faint thunder in the distance, and a heavy rain is coming.

A flash of lightning came at me like a long snake, and then deafening thunder exploded in my ear, scaring me dumbfounded. 10, heavy rain began to ravage the city.

The rain column is flying all over the sky, shooting at us like thousands of sharp arrows, which is overwhelming and powerful. Plants are struggling, desperately grasping the earth and making a final effort; Animals galloped in the rain to avoid the attack of heavy rain.

The rain seems endless, falling tirelessly, merging into water on the flat ground and expanding rapidly; Build a waterfall between the eaves and fly down. Under the curtain of the storm, the "Golden Snake" danced wildly.

Under the pressure of huge thunder, the rain is more brave and invincible. It seems that he will only give up if we surrender. This scene is really a wonder of the world, which amazes me.

1 1, the rain is more interesting. A gust of wind blows and the falling raindrops fly hard in the direction of the wind. Because the airflow of the wind is in the middle, when the raindrops from high places come into the airflow of the wind, the rain will naughtily turn into a beautiful tornado, just like a typhoon warning signal! 12, lightning is not to be outdone, and thunder and lightning are deafening.

The bright lightning flashed in the eyes and disappeared. Lightning is dazzling.

Some lightning has hung from the sky to the ground. Its appearance seems to divide the world from the middle and let them make a clean break! 13, look at the sky, it is covered with dark clouds, approaching us like a ferocious monster. The wind is blowing! I remembered the whirring sound in my ear, and the wind poured straight into the window, making people feel cold.

It is raining! Unconsciously, the rain column fell from the sky, hitting the house, falling on the road, hitting pedestrians and cars, making a plop sound, as if nature were going to hold a grand concert. 14, just after closing the doors and windows, I heard thunder. I hurried to the balcony and saw dark clouds gathering. Big drops of rain fell on the balcony, making a firecrackers sound.

At this time, my mother asked me to go to the bathroom to watch the rain. I saw a strong wind blowing a solar tube outside, dangling like a dragon dance. At this time, the raindrops changed from big drops to downpours, as if falling from the sky. The earth seemed very hungry and began to drink rain.

15, the wind is getting stronger and stronger, and young trees are uprooted. A flash of lightning, a thunder; It is raining cats and dogs.

I was so scared that I hid under the eaves without saying a word. It was raining cats and dogs, and the wind was blowing hard. Lightning was not far away. Heavy rain is accompanied by strong winds and is getting more and more urgent. The road has been flooded, and heaven and earth have become a world of water.

16 after school, raindrops jumped from the air like thousands of paratroopers and landed safely on the ground. Raindrops are connected together like a big net and hung in front of my eyes.

When it rains, the leaves of all kinds of flowers and plants are condensed with glittering and translucent water drops. Rain falls from the sky like thousands of silver lines, and rows of drained water drops fall from the eaves like a beautiful bead curtain.

17, the rainstorm "bang-bang-bang" underground. The sound of rain is particularly loud, just like bricks falling from the sky and hitting the ground, so big that there is nothing to do but sleep to eliminate fatigue.

It has been raining cats and dogs, and there is a lot of water on the road, and the water is flowing downwards.

This is nothing, and then, the strong wind blew the rainstorm badly, as if the calm sea was blown by the wind, turning up huge waves, and the rain beat on the glass windows of thousands of families. The original blue transparent windows have also been "watered" by the huge waves just now, and countless dots are like peas of different sizes, with countless white faces.

It thundered suddenly in the storm. Lightning and thunder, the wind roared, and there were few pedestrians on the road. Only adults walk home with umbrellas.

4. Suddenly, a flash of lightning jumped out of the clouds and exploded in the sky, just like a military flash bomb, which instantly lit up the world and blinded us 636f70793231335323635438+0343134313032365433.

Write an article about why the sky thunders. In hot summer, sometimes the clouds are overcast, and suddenly it rains cats and dogs, with lightning and thunder.

So, why does it thunder in summer? The reason is this: when the air is extremely unstable, it is easy to produce strong upward convection and form towering cumulonimbus clouds. Clouds are full of water vapor running up and down, which will generate static electricity. The upper end of the cloud will produce positive charge, the lower end of the cloud will produce negative charge, and the ground will also have negative charge. Although there is a voltage difference between the two negative charges, there is air as an insulator between the two negative charges, so discharge cannot occur. If the voltage difference between the two negative charges is large enough to break through the air of the insulator, the air will instantly expand and explode, releasing heat and light. Light is lightning, and the loud noise of expansion and explosion is thunder.

It thunders not only in summer, but also in winter. According to experts' analysis, lightning is a discharge phenomenon in thunderstorm clouds.

Thunderstorm clouds generally have two conditions, sufficient water vapor and strong convection. In winter, because the air is cold and dry, the solar radiation is weak, and convection is not easy to form in the air, so lightning is rare.

But sometimes when the temperature is high in winter, it will form thunderstorm clouds, leading to lightning and rain and snow. Convection is particularly strong, and it can also form hail, which will produce the so-called "winter thunder" weather phenomenon.

Since the middle of 5438+ 10, the warm and humid air flow has been extremely strong, and the temperature is obviously high. On June 5438+04, the highest temperature reached 22. 1℃, the highest in the same period in history. On June 5438+07, the strong cold air in the north went south and the two met. It not only snowed, but also thundered.

Knowing these reasons, it is not surprising that it thunders in winter.

5. Write a composition with 400 words urgently needed by Thunder. I have been afraid of thunder since I was a child. Whenever it thunders, I will hide in my mother's arms, or simply let my father cover my ears. So I can feel at ease.

That afternoon, I watched TV alone at home (my parents were at work), and I was bored and a little breathless. So when I open the window, the wind will blow in and I can breathe the fresh air outside.

But before long, the sky suddenly darkened and large dark clouds floated from a distance. It rolled like a raging wave, devouring the blue sky, and a flash of lightning flashed across the sky, followed by a loud noise roaring in my ear, just like a horrible devil hitting my heart violently with a sledgehammer. My heart felt an indescribable sense of oppression. Even my breath stopped at this moment, and raindrops the size of peas fell from the vast sky. I was afraid to the extreme, so I quickly closed the window, jumped on the bed and covered myself with a quilt. The lightning outside is still flashing desperately, and the thunder is roaring, as if to tear the whole sky. The rain fell like a waterfall, and he kept banging on the window as if looking for me.

Although I hid in the quilt, I was still shivering. Hey, when will this terrible thunder end? Chapter 2: Thunderstorm Today, my mother and I went shopping together, but on the way home, the sky in Wan Li was overcast and the rain came quietly.

I don't know when the rain climbed on people's knees, and we hurried home as fast as we could. The rain wet the ground and our clothes, and at the same time played a good beat. It's raining harder and harder, and its ticking sound is getting clearer and louder.

At this time, the sound of mahjong and voices in the street disappeared. The night became quiet and lonely. Thunder broke out with its sonorous tenor and began a long roar, which made us no longer lonely. But because of his roar, the machine of the power supply bureau broke down and the power went out, and the streets and alleys of the whole county became dark. I lit a candle and took out a book. While reading, I listened to the sound of rain and thunder.

Quiet night, beautiful rhythm, rich and loud roar are mixed together to form a symphony. The rain stopped quietly and the thunder stopped roaring. I heard raindrops dripping on the windows and leaves, like a lullaby, as if urging people to fall asleep quickly.

6. Imitating Shan Yu's "Thunder", the sky before the rain is surprisingly clear. However, gradually, the dark clouds pressed down, accompanied by a sticky feeling. In the air, the oppressive feeling began to spread, and you could smell slightly thin water vapor. Just like the smell after rain, before it rained, the whole mountain began to be filled with this unique moisture.

There is a poem:

As the poem said, sure enough, a cool breeze began to blow from the top of the mountain. but

tree

At first, the birds scattered with the leaves and chirped to the mountains, breaking the peace in the mountains.

But soon it began to rain. First, sporadic small drops of water fell to the ground and hung on the grass tips. But soon, it rained harder and harder.

Hit rocks and trees, and play a natural sport.

After a while, the rain gradually stopped. The bird stuck its head out and flew back to the tree. A drop of jade beads hanging on the leaves hit it.

On the bag. The frightened bird fluttered to a higher branch, then shook its head and licked its body.

After the rain,

It rings again, restoring calm.

7. Write a composition on the topic of lightning. Lightning and thunder are more than 65438 words.

A loud and long heavy thunder didn't pass the class, and looked out of the window. The sky is gray, and clouds of dark clouds come in droves, full of ups and downs. Day, dark, like night arrival. The dark clouds in the sky are moving fast, as if looking for the falling point, so as to make people's losses more serious. Suddenly, the lights in the classroom flashed, followed by a golden lightning, as if to split people's heads. With this "pioneer", then, a series of lightning and muffled thunder all rushed out, only to see the silver snake flying in the air, illuminating almost every corner of the earth. In an instant, the storm has "tinkled" underground lightning and huge thunder, as if the thunder Lord Dian Mu and the Four Seas Dragon King were gathering in the sky, and as if the Japanese imperialists bombed China indiscriminately in those days, which was really scary.

In the street, the trees have long been bent by the whistling wind. The dazzling white rain poured down unconsciously, like a carnival, and lightning and thunder in the sky were more like cheers, scaring pedestrians on the road to rush forward desperately, hoping to reach their destination as soon as possible. The streets have long been crowded with cars, the wipers on the cars are shaking rapidly, and the drivers in a hurry are desperately honking their horns. With the sound of rain, the wind whistling and the thunder rumbling, it is very noisy. Parents who came to pick up their children gathered around the school gate with all kinds of umbrellas and waited anxiously. The two mothers standing together are still talking about their children from time to time. They frowned for a while, Shu Mei winked and laughed for a while, and then they whispered to each other, as if they had a big surprise, completely forgetting the pouring rain, lightning and thunder. Finally, after school, parents picked up their children, took umbrellas and ran home quickly in the pouring rain.

8. How to write a composition about thunder? Thunder came from a distance and its voice was crisp.

Soon, it began to rain. The raindrops as big as beans began to scatter, then became bigger and denser.

Strips of rain are woven into a "rain net", covering the whole city. I ran downstairs and rushed into the rain curtain.

"Wow, what a heavy rain!" I suddenly feel closer to nature. Countless raindrops are alive and kicking: some draw vertical lines in the air, some are "bullying", and some simply jump around on the roof.

Whether it is drifting sideways or sideways, life is short and disappears instantly; Their life is eternal-it blends into the earth wholeheartedly! Looking from a distance, it was a haze. The hazy house seems to be a fairy tale city built by building blocks; The trees are foggy, too, and the green is faint.

The wind shook the branches of the tree warmly, and the tree danced happily with the wind waving its arms! I don't know when the rain stopped quietly and the dark clouds gradually dispersed. In the sky, the sun appeared, and a beam of golden light shone in all directions.

9. Thunderstorm Composition 600 words This morning, I sat quietly at my desk doing my Chinese homework. The bright sunshine fell obliquely on my book. The room is bright and bright, which makes people feel particularly good.

As I was writing, my eyes grew dark and the handwriting in my exercise book became blurred. Huh? Why did it get dark so soon? Before I could figure out what was going on, the sky couldn't wait to give me a shining hint: a dazzling light caught my eye. I was so scared that I didn't know it was lightning. I ran to the window and looked out. I saw the clouds in the sky chasing each other, but there was nowhere to stay. I can only bump into each other and laugh wildly at the same time. That's the winner's smug laughter, and that's also the loser's painful sound. In this way, they told people that there would be a thunderstorm.

It's getting darker and darker, similar to the brightness at six or seven in the evening. After a while, in the music of "brush brush", bean-sized raindrops fell from the sky, shining with dazzling light, just like a rain girl sowing pearl seeds. In a blink of an eye, the dry garden and dusty road have become gifts of the rain girl. Seeing this long-lost rain, those thirsty grasses quickly stood up and opened their mouths to enjoy themselves. From time to time, they gave a cheerful laugh: "Let's go down, I want to sprout, let's go down, I want to grow up!"

Raindrops hit the glass of my back balcony, "clicking" straight, and many naughty raindrops jumped in from the open window, ready to turn my back balcony into a big fish tank. The thunder is still ringing, but it has lost its momentum. This is really a wonderful lightning symphony. How sweet!

"Leigong sings first, there is not much rain." Sure enough, in a short time, the sky slowly lit up again and the rain slowly stopped. I looked out, and the dust on the pine tree was washed clean by the rain, and the leaves were shining. Their waists seemed straighter, and they stood there contentedly, like little soldiers. They are full of vitality, and looking at them reminds me of life and hope, which is refreshing.

I like rain, especially the rain in early spring, which moistens everything. Isn't there such a high evaluation as "Spring rain is as expensive as oil"?
