Will it rain and thunder in winter?

No thunder! But it will rain.

Are there any signs of thunder in winter?

It is common sense that it thunders in summer and snows in winter. However, the world is full of miracles. Although it thunders in winter and snows in summer, such a thing is little known, let alone seen, but it does happen. In China, people call the phenomenon of thunder in winter "winter thunder" and the phenomenon of snow in summer "six in the snow". In recent years, due to abnormal climate and other reasons, the phenomenon of "thunder for the winter" has appeared in some parts of China to varying degrees. Please look at the following example.

On the evening of June 6, 2003, heavy snow fell in Beijing, Tianjin and Hebei, accompanied by rumbling thunder. This rare weather phenomenon appeared near the "beginning of winter" solar term, and people talked about it one after another, and even some rumors that were not conducive to social stability appeared.

Coincidentally. June 65438+10/October 65438+6 o'clock in the morning of February 2002, several dull thunder mixed with showers broke the tranquility of dawn and woke people in Zhengzhou and Xinxiang along the Yellow River in the Central Plains from their sleep. Wenmou, a villager in Miaoli Village, Jinshui District, Zhengzhou City, who was busy in the hospital at that time, was struck by lightning and ruined his life. At about 6: 50, a big paulownia tree with a height of about 12 m and a diameter of more than 40 cm was smashed by a loud noise in a wheat field in Zhaocun, Zhao Gou Township, Zhongyuan District, Zhengzhou City. At the same time, in Wuzhi County, Jiaozuo City, hail mixed with thunderstorms also fell from the sky. It's really unusual to hear thunder, hail, beating people and smashing things for three days and nine days. For a time, there were rumors in the society. I have lived for more than 80 years and have never seen such strange weather, said an old man in fengqiu county.

Why does it thunder or even hail in winter? We know that all kinds of abnormal phenomena are not without reasons, and there must be special reasons, and the abnormal weather like "Lei Dong" is no exception. Lightning is a discharge phenomenon in thunderstorm clouds in the atmosphere, and its formation must meet three conditions, that is, there must be enough water vapor in the air, there must be power to make warm and humid air rise, and the air must be able to generate strong convection up and down. In spring and summer, due to the influence of warm and humid air flow in the south, the air is humid and the solar radiation is strong, so the air near the ground is constantly heated and rising, while the upper cold air sinks, which is easy to form strong convection, thus often producing thunderstorm clouds, which is prone to thunderstorm weather and even hail. Winter is controlled by continental cold air mass, the air is cold and dry, and the solar radiation is weak, so it is difficult for the air to form strong convection, so it is difficult to form thunderstorm clouds, thunderstorms and hail. However, at a certain time in winter in some years, the warm and humid airflow is strong, the weather is warmer (the temperature in the incident is often above 0℃), there is strong cold air in the north, and the cold and warm air meet, and the light warm and humid airflow rises sharply, resulting in unstable atmospheric structure and intensified convection. At this time, it is possible to form a thunderstorm or thunderstorm weather phenomenon. When the warm and humid airflow is particularly strong and the air convection is particularly strong, hail may also form.

Although the phenomenon of "thunder can't stop winter" is rare, it is not unique. There are many similar cases all over the world. The phenomenon of "thunder and winter" mostly occurs in the solar calendar 1 to March. At this time, it is in the transitional period between winter and summer, and the weather is hot and cold, so there are more opportunities for the phenomenon of "thunder and winter".

Through long-term and careful observation of the phenomenon of "thunder in winter", China folk summed up the law of "thunder in winter and snow in winter", that is, thunder in winter means that the air humidity is high and it is easy to form rain and snow; There is also a folk saying that "when it thunders in winter, ten cowsheds are empty", which means that when it thunders in winter, the warm and humid airflow is very active and the cold air is also very strong. It's so cold and snowy that even cows may freeze to death.

In ancient times, due to the limited ability of human beings to understand nature, the ancients believed that all abnormal natural phenomena, such as day and night, landslides, rivers drying up, winter thunder and Xia Xue, cold in the south and warm in the north, were related to human beings and were regarded as some kind of sign. Song Zhenzong used people's psychology to deceive themselves and others, and forged the so-called "gobbledygook" of 14. Whenever the "heavenly book" comes, hundreds of officials compete for beauty. Only Sun Mou, the servant of Longtuge, said to Zhenzong, "I have heard a saying,' What is Heaven!'" "God can't even speak, how can there be a book? He also hit the nail on the head to expose the ugliness of ministers: "Now when you see a wild eagle or a mountain deer, you should take it as auspicious news, even if it thunders in winter, you should also take it as auspicious congratulations. There are many people who make fun of it behind your back."

In today's highly developed science and technology, although people's understanding of various natural phenomena is much more objective than in the past, it is undeniable that the changes of the four seasons are still full of mystery in people's eyes. Therefore, we must learn to observe and understand ... >>

Why doesn't it thunder when it rains in winter?

Lightning usually occurs in strong convective weather. For example, in the tropical rain forest climate zone, the convective rain that often occurs in summer afternoons in China, and the typhoon rain that often occurs on the east coast of low latitude mainland are all accompanied by lightning.

There are two conditions for current to flow in the air. One is that clouds accumulate a lot of charges, and the other is that the discharge path is smooth. It snows without thunder. I think there are two reasons: 1 it snows mostly in winter, and the charge generated by clouds is mainly due to updraft and its friction, so there is little updraft in winter, so the charge accumulation is not much. 2. The air humidity in winter is not as high as that in summer, and the humid air is easy to conduct electricity, so the clouds in winter are not easy to discharge.

The place with the most thunderstorms in the world is Bogor (tropical rain forest climate) located in Java, Indonesia, where there are about 322 thunderstorm days on average every year, and it is known as the "Thunder Capital of the World".

Strong convective weather requires warm and humid air to rise rapidly. In summer, the temperature near the ground tends to rise rapidly, so there are often strong convective weather-thunderstorms.

There are few chances of strong convective weather in winter, but sometimes strong cold air goes south, which will also make the warm and humid air near the ground rise rapidly in some areas. At this time, the ground temperature is secondary, and the temperature difference between the ground and the sky is very important.

The air near the ground rises rapidly. On the one hand, the temperature drops sharply, which is easy to form clouds and cause rain-snowstorms. On the other hand, it is normal that the rapidly rising air rubs violently, accompanied by lightning. Thundering in winter is rare in China, but it often happens in Toronto in winter.

In order for thunder to appear, a large cloud must be formed first. Because of the strong internal convection, cloud particles collide constantly and often carry a lot of charges. When the charge accumulates to a certain extent, a large number of discharges will occur. This is lightning, which usually occurs between clouds and the ground, and sometimes between clouds. When clouds carry a lot of negative charges, they will make ground objects carry a lot of positive induced charges. In the air between the cloud and the ground, there are scattered positive charge communities, which are repelled by some ground objects because of the positive charges on the ground. The negative charge on the cloud goes down the probe and extends along the road to the surrounding small charge area. When it is close to the place where strong positive charges gather on the ground, a large number of positive charges will be sucked up and discharged. At this time, the whole flash path will appear dendritic dazzling flash, followed by a sharp temperature rise and thunderous gas produced by the sudden expansion of air. But the convection of cold air in winter is actually not strong, so even if there is thunder, it will be very, very small, so small that it can only be heard by standing next to it. Moreover, the properties of the material will be different from the normal state at low temperature, so this is also the reason why it is not felt in winter.

Where does it thunder and rain in winter?

Is thunder rare in winter? The answer should be: yes. But why does it thunder more in summer and less in winter? Briefly summarized as follows.

Thunder is formed because when the air is violently convective, the ice crystals rub against each other, which leads to the electrification of the clouds. This kind of cloud that causes lightning is called cumulonimbus cloud, and it is relatively large. Cumulonimbus clouds are also clouds that cause rainfall or snowfall.

Lightning can be subdivided into three types: thermal lightning, interface lightning and vortex lightning. Mainly based on what happened in Thundurus.

The interface thunders, and the weather forecast often says cold air front or warm air front, right? Generally, when cold air is on the ground, but it slides down quickly, the lightning caused by cumulonimbus clouds caused by the sliding of these two air layers is called interface lightning.

The cumulonimbus cloud of vortex thunder is caused by the development of low pressure air mass in the atmosphere and the strong rising air mass in the center of low pressure. In fact, the atmosphere is always balanced. . . )

The most common thunder is probably hot thunder. In summer, the ground temperature is very high, and at night, the convection in the atmosphere is often very intense (the temperature above is low), so thunderstorms are common in summer.

Thunder is really rare in winter, because the air rises smoothly in winter and it is not easy to form fierce convective clouds. In winter, thunder is most common along the coast of the Sea of Japan in the northeast of Japan (so I see lightning warnings from time to time when I watch the weather forecast in winter), as well as places in Norway and North America from the Great Lakes to the east coast. There are only a few places in the world where it snows and thunders in winter, which is really rare. The leaves should be floating again. . . ) hehe

The reason for thunder in winter is that the very cold air mass meets the warmer sea water or lake water, and a large number of rising air masses form cumulonimbus clouds, which is of course the cause of heavy snow. At the same time, it also causes thunder, often first thunder, and then heavy snow. I remember some Japanese novels describing such a scene. The sea of Japan is relatively hot because of the horse flow across it, and the geography of other places is still not clear. I will continue to study and report when I have the opportunity in the future.

Lightning in winter is rare, and there are several characteristics that lightning in summer does not have. First, the discharging clouds are different. In summer, there is a positively charged air layer above and a negatively charged air layer below. The more easily observed difference is the direction of discharge. Note that thunder doesn't always fall from the sky, but in summer, and thunder in summer is discharged from the sky to the ground. In winter, the discharge starts from the surface and goes deep into the clouds, so the thunder in winter should be particularly spectacular, right?

Finally, lightning in winter is sometimes very powerful. If the clouds are thick, they are particularly dangerous and worthy of attention.

I hope it helps you.

Why does it rain and thunder in summer and it doesn't thunder in winter?

Lightning usually occurs when there are thunderstorm clouds, and occasionally occurs during thunderstorms, nimbostratus, sandstorms and volcanic eruptions. The most common form of lightning is linear lightning, and occasionally there are strip, spherical, linear spherical, dendritic and arrow lightning. Linear lightning can be generated in clouds, between clouds and between clouds, among which the lightning in clouds and between clouds is the most, and the lightning between clouds and between clouds accounts for only one sixth, but it is the most harmful to human beings. It also thunders in winter. This is just a small opportunity. Lightning usually occurs in strong convective weather. For example, in the tropical rain forest climate zone, the convective rain that often occurs in summer afternoons in China, and the typhoon rain that often occurs on the east coast of low latitude mainland are all accompanied by lightning. There are two conditions for current to flow in air. First, the clouds accumulated a lot of charges, and second, the discharge path was smooth. It snows without thunder. I think there are two reasons. 1 It snows a lot in winter, and the charge generated by clouds is mainly due to the updraft and its friction. In winter, there is little updraft and little charge accumulation. 2. The air humidity in winter is not as high as that in summer, and humid air is easy to conduct electricity. So the clouds in winter are not easy to discharge. The place with the most thunderstorms in the world is Bogor (tropical rain forest climate) in Java, Indonesia, where there are about 322 thunderstorm days on average every year, and it is known as the "Thunder Capital of the World". Strong convective weather requires warm and humid air to rise rapidly. In summer, the temperature near the ground tends to rise rapidly, so there are often strong convective weather-thunderstorms.

Why doesn't it snow in winter and thunder in summer?

Lightning is a discharge phenomenon in thunderstorm clouds. The formation of thunderstorm clouds should meet certain conditions, that is, there should be enough water vapor in the air, the power to make wet air rise, and the air should be able to produce strong convection. Spring and summer are affected by the warm and humid airflow in the south, with humid air and strong solar radiation. The air near the ground is constantly heated up, and the upper cold air sinks, which is easy to form strong convection, so there are many thunderstorms and even hail.

In winter, controlled by the continental cold air mass, the air is cold and dry, the solar radiation is weak, and the air is not easy to form violent convection, so thunderstorms rarely occur. But sometimes the weather is warmer in winter, and the power of warm and humid air is stronger. When the cold air in the north occasionally goes south, the warm and humid air is forced to rise, and the convection intensifies, so-called "thunder into winter" phenomenon will occur. Meteorologists also say that the occurrence of thunderstorms does not depend on the temperature itself, but on the upper and lower distribution of temperature. That is to say, although the temperature is not high in sunny days, if the temperature difference between the upper and lower reaches a certain value, strong convection can also be formed, resulting in thunderstorms. Thundering in winter is rare in China, but it often happens in Toronto in winter.

When the air is extremely unstable, it is easy to have 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 be positively charged. Then, there is air as an insulator between the positive and negative charges. If the voltage difference between positive and negative charges is large enough to break through the air of the insulator, the air will instantly expand, explode, heat and glow.

Why doesn't it thunder when it rains in winter?

People's breathing is actually related to atmospheric pressure, just like altitude sickness caused by low atmospheric pressure at high altitude.

When it rains, children are caused by low air pressure;

Because there is more water vapor in the air in rainy days or before it rains, the average molecular weight of the air decreases, that is, the air density decreases.

Causing the air pressure to drop. The higher the temperature, the more the rainy weather pressure drops, so the predecessors will feel chest tightness when it rains in summer.

People's inhalation is forced in by external atmospheric pressure, and of course the change of oxygen content in the air is also related. ,,

Will it rain and thunder in winter?

Believe it or not, it wants to thunder or it will thunder! As long as it is not divided, there is no difference between good and bad.
