Why snow doesn t thunder in winter!

When it snows in winter, there is very little updraft, so the accumulation of electric charge is not much, and the humidity of the air in winter is not as great as in summer, so the moist air is easy to conduct electricity, so the clouds in winter are not easy to discharge. So normally, we don't hear rumbling thunder in the winter.

Beat. Thunder is a large electric current flowing through the air. Two conditions are required, one is that the clouds have accumulated a large amount of charge, and the other is that the discharge route is smooth and snowy and does not thunder, I think there are two reasons.

1 is that it snows a lot in winter, and clouds produce charge mainly because of updrafts and its friction, and there are very few updrafts in winter, so there is not much charge accumulation.

2. The humidity of the air in winter is not as great as in summer, and the humid air is easy to conduct electricity, so the clouds in winter are not easy to discharge.

To understand this problem, we also need to start with the principle of thunder. Thunder is a loud sound caused by a vacuum caused by a cloud discharge (lightning), so how does lightning come about? It turns out that lightning is a cloud discharge, and its generation depends on strong convective weather

When the ground temperature rises, the air is heated and rises, and at this time it encounters cumulonimbus clouds, the hot air will drag the water droplets in the cloud upward, these water droplets merge with other water droplets on the way up to become large water droplets, when they reach the top of the cloud layer, the weight of the water droplets is already very large, and they can no longer be dragged by the air, so they begin to fall, and the water droplets collide with each other when they land, and the electrons in the water are knocked out at the same time when they continue to increase, so that the water droplets are positively charged, and the free electrons rise with the air to the top of the clouds. So the top of the cloud is negatively charged and the bottom is positively charged. As said on the first floor, when the clouds reach a point where they can penetrate the air, an electric discharge occurs, and thunder occurs. In winter, the ground temperature is very low, which does not cause a wide range of strong updrafts, and naturally there is no strong convective weather like in summer, so there is no thunder in winter.

Thunder is the accumulation of electric charges in the clouds that causes a potential difference between the clouds or between the clouds and the ground, and when the potential difference is large enough to penetrate the air layer, the lightning forms a bird. Just like a capacitor, the two layers of metal plate are heaven and earth, and the medium in the middle is air, and if the pressure is too high, the capacitor will break down, and then there will be a bang. In winter, when the temperature is low, the water vapor becomes solid, and the air humidity is small, so it is not easy to break down, and it is not easy to thunder.

Thunder can occur on a snowy day.

In winter, when the sky is overcast and the temperature in the clouds above above zero is below freezing, the water vapor in the clouds condenses into snow. When snowflakes fall from clouds, if the air temperature near the surface layer is high, the snowflakes will melt into raindrops. Conversely, if the temperature near the ground level is low and the snowflakes cannot melt, then it will snow.

Thunderstorms are caused by strong convection of warm and moist air in local places, and the sharp rise of warm air produces violent vibrations of cumulonimbus clouds, which will accumulate a large amount of electric charge and produce lightning phenomena. At that time, the ground temperature was around zero degrees Celsius, and the conditions for snow were available. At high altitude, warm and moist air climbs violently, and a strong convection phenomenon occurs, forming cumulonimbus clouds, so there is a weather phenomenon of snow on one side and thunder on the other.

Thunder is a natural phenomenon, and when it rains, some clouds in the sky have positive poles and some negative poles. When two clouds collide, lightning strikes, and at the same time emits a lot of heat, heating and expanding the surrounding air. The air that is heated and expanded in an instant will push the surrounding air, causing a strong **-type vibration.

This is thunder.

There is no sign of thunder on the winter solstice, and winter thunder is a natural phenomenon.

The ancients classified the thunder that stung in the solar terms as spring thunder, so the thunder that appeared in the first month was classified as "winter thunder". The folk proverb "thunder and snow in winter" means that thunder in winter is a harbinger of heavy snowfall. And when it snows, thunder is "thunder and snow".

Experts from the Zhejiang Provincial Meteorological Observatory explained that although this phenomenon is rare, it is quite normal. The convergence of cold and warm air is more intense, and the warm and humid airflow is rapidly lifted to form vertical convection, which will form thunderstorm clouds, resulting in "thunder and snow". This phenomenon is rare due to the fact that the low-lying and ground temperatures are inherently low in winter, and there are not many opportunities for convection to be strong enough to produce lightning.

There were thunder and snow in some areas of the Yangtze River Delta during the snowfall process, and there were two main factors in the expert analysis: first, the temperature roller coaster before the cold air came, and the temperature recovery in the warm area was relatively strong, resulting in a relatively high ground temperature when the cold air arrived; Second, the cold air is strong, fast and cools quickly, which aggravates the instability of the convection.

The reporter found that there are folk proverbs about thunder in winter, such as "thunder and snow in the first month, rain does not stop in February, less seedling water in March, and the seedling festival in April" and "thunder in the first month, a great drought of 188 days (that is, 180 days)". It is said that there will be continuous rain after "thunder and snow", but it is said that there will be a major drought in the back, and it seems that the folk sayings are also contradictory.

Experts believe that from a scientific point of view, thunder in the first month is a normal natural phenomenon, and has nothing to do with auspiciousness or not.

1. What's going on with thunder on a snowy day?

2. What's going on with thunder on a snowy day.

3. What's going on with thunder on a snowy day.

4. What is the situation of thunder on a snowy day?

1.This is due to the fact that thunderstorm clouds are sometimes formed by high temperatures in winter, resulting in rain and snow weather, and rain and snow weather.

2.If the convection is particularly strong, hail can also form.

3.Under normal circumstances, the air is cold and dry in winter, and the solar radiation is relatively weak due to hail, so it is not easy to form convection in the air, so there is rarely thunder and lightning.

1. Folk sayings.

There is a folk saying: thunder strikes winter, nine out of ten bullpens are empty. It is a very rare event that thunder in winter and snow in summer are both very rare events in the Swift Response Brigade, so they are given a bad omen by the people.

The folk stool believes that thunder in winter indicates that there will be a big ** in some places; At the same time, it is also said that winter thunder can be a great disaster of bad luck.

2. Scientific explanation.

In fact, this is a very normal climatic phenomenon, especially in recent years, which has been more and more common. Winter thunder is caused by a sudden encounter of cold air, which can then cause heavy snowfall or even hail.

Question 1: Why doesn't it thunder when it snows Snow mostly in winter, and clouds produce electric charges mainly because of updrafts and its friction, and there are few updrafts in winter, so there is not much charge accumulation 2 is that the air humidity in winter is not as great as in summer, and moist air is easy to conduct electricity, so clouds in winter are not easy to discharge.

Question 2: Why does it thunder when it rains, and it doesn't thunder when it rains The thunderstorm phenomenon is a product of thunderstorm clouds. Thunderstorm clouds are strongly developed convective clouds that require strong upward motion and abundant water vapor conditions, both of which are generally available in summer.

As a result, thunderstorm clouds usually form only during the summer months. The cloud system that forms snowfall in winter is not thunderstorm clouds (convective clouds), and there is no thunderstorm phenomenon.

Question 3: Why doesn't it thunder when it snows Snow is mostly in winter, and clouds produce electric charges mainly because of the upperair hall reflux and its friction, there are few updrafts in winter, so the charge accumulation is not much 2 is that the air humidity in winter is not as large as in summer, and the moist air is easy to conduct electricity, so the clouds in winter are not easy to discharge.

Question 4: Why doesn't it thunder when it snows in winter (; o o not lightning? In winter, the climate is cold and dry, the liquid water vapor is inactive, and the positive and negative electrodes are not easy to collide and move. There will be no thunder and lightning.

Question 5: Why does it thunder when it rains, but it doesn't thunder when it snows The phenomenon of thunderstorms is a product of thunderstorm clouds. Thunderstorm clouds are strongly developed convective clouds that require strong upward motion and abundant water vapor conditions, both of which are generally available in summer.

As a result, thunderstorm clouds usually form only during the summer months. The cloud system that forms snowfall in winter is not thunderstorm clouds (convective clouds), and there is no thunderstorm phenomenon.

Snowfall is due to the cold weather, water vapor condenses into ice crystals, and the weather is still dry after a large number of ice crystals are formed, and it is not easy to produce strong collision of cold and warm air currents, so it is not easy to thunder when it snows.

The reason for the formation of thunder and lightning is that the weather is cloudy and humid, and the cold and warm air masses rub and collide with each other, producing a large number of charged particles, resulting in thunder and lightning weather.

Thunderstorm cloud conditions.

In general, two conditions are required for thunderclouds to form: sufficient water vapor and vigorous convective movements.

From the first point of view, it is one of the reasons why lightning is not easy to occur in winter. We know that the climate in winter is much drier than in summer, especially in the north. Especially in the high altitude, due to the low temperature, the clouds are also full of condensed snow, rather than rain clouds like in summer.

Therefore, if it is too dry, it is not easy to generate lightning.

As for the second point, it is also the reason for the lack of thunder and lightning in winter. In winter, the sun doesn't shine as hard as in summer. In summer, strong sunlight causes the air temperature on the ground to rise.

We know that hot air has a low density, so it rises rapidly and has strong convection with relatively cold air masses at high altitude. This process is continuous, with the lower temperature air mass being squeezed to the ground, and then heated up and squeezed back, with continuous strong convection.

Snow does not thunder because thunder and lightning are the discharge phenomenon in thunderstorm clouds, and the formation of thunderstorm clouds must have certain conditions, that is, there must be sufficient water vapor in the air, there must be the power to make the moist air rise, and the air must be able to produce violent convective movement. In winter, due to the control of the cold air mass of the continent, the air is cold and dry, and the solar radiation is weak, the air is not easy to form violent convection, so it rarely thunders when it snows.

Snow and thunder are due to the strong force of warm and humid air, and when the cold air arrives, it meets the warm and humid airflow, resulting in strong convective weather, which triggers thunder and lightning activities. The formation of thunder and lightning must have certain conditions, that is, there must be sufficient water vapor in the air, there must be the power to make the warm and humid air rise, and the air must be able to produce violent upward and downward convection movements, and the winter climate is cold and dry, and the air is not easy to form violent convection, so thunder is not common in winter, and there are fewer cases where it is snowy and comes from thunder. <

Snow and thunder are due to the strong force of warm and humid air, and after the arrival of cold air, it meets with warm and humid airflow, resulting in strong convective weather, which triggers thunder and lightning activity. The formation of thunder and lightning must have certain conditions, that is, there must be sufficient water vapor in the air, there must be the power to make the warm and humid air rise and crack, the air must be able to produce violent up and down convection movements, and the winter climate is cold and dry, and the air is not easy to form violent convection, so thunder is not common in winter, and there are fewer cases of both snow and thunder.

Thunder is also possible in winter when it snows. It's just very rare.

Thunder and lightning usually occur in severe convective weather. For example, the tropical rainforest climate zone, the convective rain that often occurs in the summer afternoon in China, and the typhoon rain that often occurs on the east coast of the low-latitude continent are often accompanied by thunder and lightning.

The most thunderstormed place in the world is Bogor (tropical rainforest climate) on the Indonesian island of Java, where there are an average of about 322 thunderstorm days per year, and is known as the "thunder capital of the world".

Severe convective weather requires a warm and moist airflow to rise rapidly. In summer, it is easy for the ground to heat up quickly, so it is common to have strong convective weather - thundershowers.

In winter, there is less chance of strong convective weather, but sometimes strong cold air moves southward, which can also cause warm and moist air near the base to rise rapidly in some areas. At this time, it is common to have snowstorms and other events, and it is normal for them to be accompanied by thunder and lightning. Sakura stupid.

1. Snow and thunder are bad omen, and there will be disasters brought by nature, such as drought, always cloudy and rainy, and there will be natural disasters. Snow and thunder in the first month of the year, the ancients thought it was an unlucky omen. It is written in the ancient poem "The Evil One":

Winter thunder shakes summer rain and snow, heaven and earth are together, dare to be with you! Comparing thunder in winter to "snow in summer" is considered to be a natural phenomenon that is impossible to produce high wisdom.

2. Thunder in winter, commonly known as "winter thunder" or "thunder in winter". In winter, "thunder winter" is uncommon, but it exists. However, in ancient times, due to the underdevelopment of science and technology, people believed that thunder in winter was a bad omen.

Day and night are reversed, and the seasons are out of order, which is a bad omen in ancient times. Thunder strikes winter, nine out of ten bullpens are empty. In the eyes of the ancients, winter is the season when all things are hidden and closed, and if there is thunder in winter, it is called "disturbing the sun".

In winter, the yang energy of heaven and earth is to be hidden. From a celestial point of view, there should be no thunder in winter. If there is thunder in winter, it means that the heavens and the earth cannot hide the yang energy, and the animals will definitely suffer.

3. The weather signs of snow and thunder are a few days before the incident, the local temperature is often above 0 degrees, the humidity is large, and on the day of the incident, there is strong cold air affecting the local area, when the strong cold air and the ground are relatively warm and humid. When the air is in contact, the warm and moist air with a light weight is violently lifted, and the limb of the car causes the formation of thunderstorm clouds due to stratification instability, and the temperature of the thunderstorm clouds generated by the lifting should be below 0 degrees, so there will be snow and thunder.
