Why does it thunder?

Question 1: Why does it thunder and rain in the sky? Some clouds in the sky are positively charged and some are negatively charged. When two clouds meet, they will discharge, emit bright and bright lightning, and at the same time release a lot of heat, which will make the surrounding air heated, expand and make a loud noise. This is thunder.

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 in winter, sometimes the temperature is high and the warm and humid air flow is strong. When strong cold air occasionally moves south in the north, warm and humid air is forced to rise, and convection intensifies, leading to the formation of thunderstorm clouds, thunder and lightning, 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.

It is reported that one night in the early spring of 1970, the north wind roared in the middle and lower reaches of the Yangtze River in China, and it was snowing with rare goose feathers. Suddenly, there was lightning and thunder in the sky, which is a rare weather phenomenon and makes people feel strange. There is also heavy snow accompanied by thunder in Luxi Lantern Festival this year. So, why does it thunder on snowy days?

Lightning and thunder are common weather phenomena in summer, while it usually snows in winter. These are two completely different weather phenomena. However, as long as the weather in a certain place has the conditions of snow and thunder at the same time, these two completely different weather phenomena can appear at the same time.

In winter, the sky is overcast, the temperature of the upper clouds is below zero, and the water vapor in the clouds condenses into snow. When snowflakes fall from the clouds, they will melt into raindrops if the air temperature near the ground is high. On the contrary, if the temperature near the ground is low and the snow cannot melt, it will snow.

Thunderstorms are caused by strong convection of warm and humid air in some places. The sharp rise of warm air produces the violent vibration of cumulonimbus clouds, which will accumulate a lot of charges and produce lightning.

Question 2: Why does it thunder on snowy days? Thunder is a common weather phenomenon in summer; Snow, mainly in winter, is two completely different weather phenomena. But as long as the weather situation at a certain time and place has the conditions of snow and thunder at the same time, these two completely different weather phenomena can appear at the same time in one day.

In winter, when the sky is overcast and the temperature in the upper clouds is below 0℃, the water vapor in the clouds condenses into snow. Snowflakes fall from the clouds. Do people see snow or rain on the ground? This depends on the temperature within a few hundred meters of the surface. If the temperature near the surface layer is relatively high, when the snow falls, it will melt again at the low altitude near the surface layer and become raindrops. At this time, what we see is rain. On the contrary, if the temperature near the ground is low and the snow cannot melt, it will snow. Generally speaking, when the ground temperature is lower than 3℃ or 2℃, it will snow.

Thunderstorms are caused by the rise of warm and humid air for some reason (such as moving on the top of cold air, or influenced by topography, such as the slope of a mountain, etc.). ); When warm air rises sharply and produces cumulonimbus clouds, thunderstorms are prone to occur.

Let's take a look at the weather in the middle and lower reaches of the Yangtze River in China on the evening of March 1970. J at that time, the cold air near the surface layer went from North China to the lower reaches of the Yangtze River through the northern Yellow Sea, and the temperature was very low. After the evening, the temperature in the middle and lower reaches of the Yangtze River dropped to about o℃, which made it possible for it to snow. What was above the cold air at that time? The strong warm and humid airflow from the Southern Ocean just meets the cold air in the middle and lower reaches of the Yangtze River and climbs violently along the low-level cold air, so there is a strong convection phenomenon in the layered cloud that is about to snow, forming a cumulonimbus cloud, so there is a weather phenomenon that it snows while thundering.

Someone said, "It's a bad omen to thunder in snowy days." This is mostly nonsense without scientific basis, but the old society was influenced by feudal superstition because of its ignorance of weather phenomena.

Question 3: Why does it thunder in the sky? Not bad, it sounds good, and the style of the song is the same as before. Worth listening to!

Present lyrics:

A group of bloodthirsty ants are attracted by carrion.

I looked at the lonely scenery with a straight face.

Losing your love begins to become clear.

No, what do you care?

Pigeons no longer symbolize peace.

Someone finally reminded me to tie my hands. I'm a slave now

I use beautiful rhymes to describe the plundered love.

I should hide here. The night is unclean.

And give you memories all night, occupying the stars all over the sky.

The white rose for you withered in the pure black flower season.

At midnight, the branches were strangely quiet.

Listen to my black coat. I like mine.

The life that ghosts lead.

Ah, it's foggy all around

I'm in an empty cemetery.

I still love you when I am old.

Serenade Chopin for you

In memory of my dead lover

Sounds like the night wind.

heartbreaking

Tap the piano on the keyboard with your hand.

I think you think too carefully.

You are where you are buried.

Serenade Chopin for you

In memory of my dead lover

I hid my name for you.

Play the piano in the moonlight

The feeling of your heartbeat

Still so warm and intimate

Miss your bright red lip prints

Those broken-winged dragonflies are scattered in this forest.

I have no sympathy in my eyes.

Losing your tears is cloudy and heartless.

I can't even smile without you.

I stood on the roof with anticipation.

Laugh at my sadness

Like a dry well without water.

I have exhausted my confidence.

I regret waiting for love.

Serenade Chopin for you

In memory of my dead lover

Sounds like the night wind.

heartbreaking

Tap the piano on the keyboard with your hand.

I think you think too carefully.

You are where you are buried.

Serenade Chopin for you

In memory of my dead lover

I hid my name for you.

Play the piano in the moonlight

The feeling of your heartbeat

Still so warm and intimate

Miss your bright red lip prints

A group of bloodthirsty ants are attracted by carrion.

I looked at the lonely scenery with a straight face.

Losing your love begins to become clear.

No, what do you care?

Pigeons no longer symbolize peace.

Someone finally reminded me to tie my hands. I'm a slave now

I use beautiful rhymes to describe the plundered love.

Question 4: Why does the sky thunder? Sad and crying.

Question 5: Why does it thunder on rainy days? Where did it come from? Because there are different positive and negative charges in the cloud, positive and negative charges attract each other. When two clouds attract and collide, they make a sound, which is thunder.
