Why is thunderstorm weather so dangerous? How to protect it?

Thunderstorm is an atmospheric discharge phenomenon, which mainly occurs in tropical and temperate regions. It is a meteorological disaster caused by bad weather changes, which often occurs in cumulonimbus clouds. Thunderstorms can be accompanied by lightning, lightning, strong winds and significant precipitation, and usually last less than 2 hours. Thunderstorms usually occur in spring and summer, and June and July are thunderstorm-prone seasons in South Asia.

Simply put, thunderstorm is a large-scale and persistent lightning phenomenon. Clouds are made up of small ice crystals or water droplets. When there is strong convective weather, there will be friction and collision between clouds or between clouds, and a lot of free charges will be generated in the clouds. The distribution of these charges in the cloud is very complicated. When the potential difference reaches a certain level, there will be a violent discharge phenomenon, which is lightning. During the discharge process, high temperature will be generated, which will make the surrounding air expand rapidly and the shock wave will form lightning. Because light travels much faster in the air than sound, we all see lightning first and then hear thunder.

Thunderstorms release a lot of energy, and the electricity released in just 1 sec is enough for a city to use for a long time. The bright light drawn in the sky is lightning, and lightning is plasma, and the temperature can reach 10000 ~ 20000 degrees Celsius, which is higher than the surface temperature of the sun. Ordinary electric shocks can kill people, not to mention such a powerful thunderstorm. More than1000 people die in India a day, which proves that the lethality of thunderstorms is amazing.

If the clouds contain a lot of free charges and are close to the ground, and the electric field intensity between the clouds and the ground can penetrate the air, lightning may occur. These lightning strikes buildings, which may not only damage buildings, but also cause fires. If you hit someone, the chance of survival is almost zero.

Thunderstorms often occur in summer in China, especially in the southern mountainous areas. This incident in India reminds many people not to underestimate the power of nature.

You should stay indoors during a thunderstorm. People who work outdoors should hide in buildings. Now many high-rise buildings have lightning protection facilities, even if they are struck by lightning, it will not have much impact. Even without lightning protection facilities, buildings can play a shielding role. Don't stand on the top of the mountain, and don't go near objects with high conductivity, such as tall trees. After lightning strikes an object, the current will spread through the ground, so don't lie on the ground, kneel down and minimize the contact area with the ground. In addition, you should also avoid using telephones or other electrical appliances with plugs in thunderstorm weather, which may not only damage the equipment, but also cause personal injury.

Farmland is generally located in an open area, and there are few tall trees nearby, so farmers working in the fields become the targets of lightning strikes. Thunderstorms are often accompanied by precipitation, and water in nature is a conductor. Even if it is not struck by lightning, when lightning falls near the human body, the conductivity is enhanced by rain, which will electrocute people.
