Thunderstorm can you run, what can t you do on a thunderstorm

Don't run around when you encounter a "spherical mine".

Running in a thunderstorm makes people more unsafe and more susceptible to lightning strikes. Thunder and lightning are divided according to their shape, and can be divided into chain lightning and spherical thunder. Spherical thunder is a thunder shaped like a ball.

In the past, Jiangsu rarely appeared, mainly concentrated in Guangdong, Guangxi and other regions. Because such an area is surrounded by the sea and the climate is hot and humid. However, in recent years, due to abnormal weather, there have been several spherical mines in Jiangsu Province.

Strange spherical mines float at low altitudes, but the reason for their formation is still unknown. Lightning protection experts say that the diameter of a small spherical mine is generally only a few centimeters, the largest is tens of meters, and most are tens of centimeters. Spherical lightning is extremely powerful, and its core temperature is generally more than 1000 degrees, and even thousands of degrees Celsius.

The reason why it is recommended that the public do not run when encountering spherical mines is because spherical mines have the habit of "following the trend", that is, following the movement of the air current, and the best way to avoid danger is to immediately hold their heads with their hands and squat down with their feet together.

Don't wear your watch during a thunderstorm.

Experts from the Jiangsu Provincial Lightning Protection Center said that metal objects cannot be used during thunder. "It's like a metal pendant, or a watch, and it's better not to be exposed, or not to wear it at all. Experts say that lightning is "selective", and they are more "fond of" metal objects, and if they wear too many metal objects, they may be "targeted" by lightning.

In addition, it is best not to connect ** in the event of lightning. A few years ago, there was an accident in Juyongguan, Beijing, where a mobile phone was struck by lightning. When lightning occurs, people who are outdoors should take shelter in a safe and sheltered place as soon as possible.

When indoors, try to stay away from metal doors and windows, don't get too close to the power supply, and don't turn on electrical appliances such as TVs and computers, because lightning is likely to "come in" through power lines and data transmission lines.

When the umbrella is hit with lightning, you need to grab the plastic handle.

If you must go out during a thunderstorm, citizens should pay more attention to measures, and even how to hold an umbrella is "knowledge". "The current umbrellas are all metal handles, which one should I hold safely? Did you turn off the umbrella?

In this way, contact with metal is avoided, and there is no fear of lightning strikes? Ms. Zhang, a citizen, asked. Lightning protection experts say that the top of the handle of the old-fashioned umbrella is pointed, and this shape is similar to the lightning rod on the roof of the house.

Again, it's better not to be outside when it rains, but if it doesn't work, just hold the plastic handle at the bottom. ”

In addition, experts remind that it is not advisable to enter isolated sheds, sentry boxes, etc. in outdoor open spaces during thunderstorms. Do not stand under large trees, towers, or billboards to take shelter from the rain, and if you have to, keep a distance of 3 meters from tree trunks, squatt, and keep your legs close together to prevent damage from dangerous stride voltages.

You can run if you are not afraid of a cold Thank you.

Thunder doesn't have to rain.

In the early stages of raindrop formation, cloud droplets mainly rely on the continuous absorption of water vapor around the cloud body to condense and condense themselves. The water vapor energy in the cloud should be continuously replenished and replenished, and when the cloud droplets in the cloud increase to a certain extent, they will become raindrops, but in the process of thunder, the change of cloud layer may change the water vapor.

The content affects the formation of water droplets, and if the conditions for rainfall are not met, there will be only thunder but no rain.

The cause of thunder is that the clouds in the sky have positive poles and 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.

The cause of rain is that the water on the surface of the land and the sea evaporates into water vapor, and the water vapor rises to a certain height and becomes small water droplets when it is cold, and these small water droplets form clouds, which collide with each other in the clouds and merge into large water droplets, and when it is too large for the air to support, it falls from the clouds and forms rain.

1. When thunderstorm and lightning, do not dial and answer, and unplug the ** line. Mobile phones can be used normally, but generally try not to receive mobile phones outdoors or indoors near windows.

2. During thunderstorms and lightning, do not turn on TVs, computers, VCD players, etc., and unplug all power plugs to avoid hurting people and damaging electrical appliances.

3. Don't stand under the light bulb and don't take a shower.

4. Try not to go out, if you must go out, it is best to wear rubber shoes and a raincoat, which can play an insulating role in lightning.

5. Try not to open doors and windows to prevent lightning from hitting the room directly.

6. When you encounter thunder and lightning in a car, do not stick your head and hands out of the window.

7. When the thunderstorm is large, stay away from the trees, try not to run in stride, and choose buildings to shelter from the rain. You can also shelter from the rain in the car, because the car is a metal shell, and people will neither be injured by induction lightning nor be directly hit by lightning.

8. Do not pull the wire of the drying clothes and bedding to the windows and doors.

9. Do not wear wet clothes, hats, shoes, etc. to walk around during heavy thunderstorms. For sudden lightning, you should immediately squat down to reduce your height, and at the same time bring your feet together to reduce the harm caused by the stride voltage.

10. When lightning strikes, do not approach all power facilities, such as high-voltage wires and transformer appliances.

11. Immediately stop outdoor swimming, boating, fishing and other water activities.

12. If many people gather outdoors, do not squeeze each other to prevent the power supply from being struck by lightning.

Summer is the season of thunderstorms, thunderstorms are very dangerous, and we need to pay more attention in summer.

This tells you what you need to pay attention to during a thunderstorm:

Method steps.

1. Do not take shelter from a large tree.

In thunderstorms, it is very dangerous to go under the big trees, and the thunder and lightning will be transmitted to the ground through large numbers, and the voltage of the thunder and lightning is very high, so do not take shelter under the big trees during the thunderstorm.

2Do not take shelter from the rain near tall buildings.

Tall buildings are the most common place where lightning strikes occur, but tall buildings will have lightning rods, and the electricity from lightning strikes will reach the ground with lightning rods, and they are prone to lightning strikes next to tall buildings.

3Don't use your phone during a thunderstorm.

In the past two years, many news reports have reported lightning strikes caused by using mobile phones to make ** text messages during thunderstorms, telling us not to use mobile phones during thunderstorms.

4. Do not use the network during thunderstorms.

Once, I was surfing the Internet in the dormitory of the unit, and suddenly there was a thunderous sound, deafening, as if it was overhead, with lightning and thunder, the monitor suddenly flashed, and the computer was shut down.

5. Pay attention to TV during thunderstorms.

One night during the summer vacation last year,Thunderstorm,The power cord of my TV was plugged into the socket and not unplugged,The next morning I watched TV,I found that the TV could not be turned on,Later, after the sale,It took 500 oceans to repair。 The motherboard of the TV was damaged by lightning, so if you don't watch TV in the summer, you must unplug it, cable TV cables, etc.

6. Save yourself in the open area in the event of a thunderstorm.

Sudden thunderstorms on open ground are very dangerous, and lightning will be more likely to hit things protruding from the ground, so when we walk through open ground and encounter thunderstorms, especially lightning strikes, it is best to reduce our height as much as possible.

end precautions.

Try not to go out during thunderstorms, and pay attention to the weather forecast before going out.

On a rainy day, stir-fry a side dish and drink a little wine at home, and it is very refreshing on a cloudy day.

Thunder will also occur when it rains in spring, haven't you heard of spring thunder? It rains and does not thunder in winter, the reason: thunder is a large current flowing in the air requires two conditions, one is that the clouds accumulate a large amount of charge, the other is that the discharge path is smooth, there are two reasons for not thundering in winter 1 is that the snow is more in winter, and the cloud generates charge mainly because of the updraft 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 humid air is easy to conduct electricity, so the clouds in winter are not easy to discharge.

Thunder and lightning are the phenomenon of electrical discharge in thunderstorm clouds. There are certain conditions for the formation of thunderstorm clouds, that is, there must be sufficient water vapor in the air, there must be a power to make the moist air rise, and the air must be able to produce violent convective movements. In spring and summer, due to the influence of the warm and humid airflow from the south, the air is humid, and at the same time, the solar radiation is strong, the air near the ground is constantly heated and rises, and the cold air in the upper layer sinks, which is easy to form strong convection, so there are many thunderstorms and even hail.

In winter, due to the control of the continental cold air mass, the air is cold and dry, and the solar radiation is weak, the air is not easy to form violent convection, so thundershowers rarely occur. However, sometimes the weather is warm in winter, and the warm and humid air is stronger, and when the strong cold air in the north occasionally goes south, the warm and humid air is forced to rise, and the convection intensifies, thundershowers will be formed, and the so-called "thunder winter" phenomenon appears. Meteorologists also say that the generation of thunderstorms does not depend on the temperature itself, but on the distribution of the temperature up and down.

In other words, although the temperature is not high in winter, if the temperature difference between the upper and lower reaches a certain value, strong convection can also be formed, resulting in thunderstorms. Winter thunderstorms are rare in China, but they are common in winter in Toronto, Canada.

When the air is extremely unstable, it is easy to have a strong upward convective movement, and form a towering cumulonimbus cloud, the cloud is full of water vapor rushing up and down, it will produce static electricity, the upper end of the cloud will produce a positive charge, the lower end of the cloud will produce a negative charge, and the ground is a positive charge, then, there is air as an insulator between the positive and negative charges, if the voltage difference between the positive and negative charges is large enough to break through the air of the insulator, so that the air expands in an instant**, heats up and glows, and the light is lightning, expanding** Making a loud noise is thunder.

It doesn't have to be thunder when it's raining, and it's not necessarily raining when it's raining. However, thunder often rains, because thunder often occurs when the air state is unstable, there is convective cloud activity in the atmosphere, two convective clouds with different or opposite directions of movement contact each other, resulting in friction, static electricity is generated between the two convective clouds, and electrostatic discharge forms thunder. If there are hot and humid clouds and cold and dry clouds in the convective clouds, the convection of the two clouds will change the internal state of the hot and humid clouds, causing the water vapor in them to precipitate and become raindrops falling to form rain.

If the convection of the two convective clouds does not constitute a condition for rain, then it will not rain.

The Earth's revolution produces seasonal changes.

Since the earth is an opaque planet, the sun and stars give the earth light, and the side that shines on the sun is day, and the other side is the night. The earth is constantly rotating from west to east around its axis of rotation, and the phenomenon of celestial bodies rising in the east and setting in the west is a reflection of the earth's rotation. One rotation of the earth is equivalent to the week when the sun rises in the east, sets and rises again, and it is also our daily day.

As the Earth rotates, it revolves around the Sun, which rotates from west to east. The orbit of the Earth's revolution is an ellipse that is close to a perfect circle, and the Sun is located in a focal point. The Earth's orbital period is one year, and astronomically it is 365 days, 5 hours, 48 minutes and 46 seconds.

The angle between the Earth's orbit (ecliptic plane) and the Earth's rotation plane (equatorial plane) is 23 degrees 26 minutes, which causes the direct point of the Sun to move between the Tropic of Cancer in a one-year cycle, forming the four seasons in temperate regions.

On March 21 every year, the direct sun point moves from south to north to the equator, and the global day and night are equinox, which is our vernal equinox day, and on June 22, the direct sun point moves north to the Tropic of Capricorn, becoming the longest day in the northern hemisphere, which is what we call the summer solstice, and then the direct sun point turns to move south, and on September 23, it hits the equator directly, which is the autumnal equinox, and on December 22, it moves to the Tropic of Capricorn, and it is our winter solstice.

The change of seasons is actually the result of the combined effect of the earth's rotation inclination and revolution around the sun, without one of these conditions, the change of seasons will not occur, and everything on the earth will change accordingly.

Thunder is raining, but it travels far away. Therefore, it is not the place where you hear thunder that you can see rain, so there is a saying that it does not rain when it thunders alone, which is due to the fact that you hear thunder but do not see rain!

It is not certain that there will be thunder first and then rain, it will rain if there is no thunder first, and it will rain first and then rain, it is just the same kind of situation.

There is a natural phenomenon of rain first, and then thunder, in the summer encountered, the beginning of the dark clouds quickly pressed over, there was no thunder, it rained heavily, non-stop, but after a long time, there was thunder, sometimes the rain is almost over, there is thunder, after the rain soon stopped, the clouds moved elsewhere, such a situation often appears in the local formation of thunderstorms.

Some thunderstorms often last for a while, and then there is thunder.

Sometimes light rain turns to thundershowers, that is, it starts to rain lightly, and after a while, thunder appears, and sometimes the rain will increase.

Why does it rain and thunder rain when it rains.
