Solar terms daren apple

On the day of the solar term, thunder sounded, indicating the coming of spring and the beginning of spring ploughing. For thousands of years, people have started a new farming season according to the thunderous solar terms. So, in the new year? Scared? It is very important for farmers to know when the first spring thunder will sound. Because on the day of the solar term, the spring thunder suddenly moved and everything began to wake up. After the shock, the farmers who have rested for a winter have to start busy with farm work again. ? Spring ploughing can't rest after the scare? 、? The farmers were busy when the spring thunder sounded. The stinging sound of spring thunder woke up everything that had been hibernating for a winter, and also knocked on the gongs and drums of farmers working in the fields.

Thunder not only happened in summer, but began on the day of spring.

But compared with spring, people are more likely to see thunder in summer. Old people have warned since childhood, when it rains and thunders, don't stay in an open place, and don't hide under a tree. Even when it rains, you need to unplug all the switches and sockets at home, for fear that thunder will damage the electrical appliances at home.

When it thunders in rainy days, lightning is a discharge phenomenon between charged clouds or between charged clouds and the ground, and it is also a very common phenomenon in nature. The voltage between charged clouds and the ground can be as high as 106~ 108 volts. Such a high voltage will often cause damage to buildings, trees and electrical equipment, and cause human and animal casualties.

Therefore, it is particularly dangerous to shelter from the rain outdoors when it thunders and rains. Especially hiding under a tree from the rain.

Do trees act as the ground during a thunderstorm? Protrusion? Lightning current will pour down through the trunk. However, in the process of lightning current pouring down, lightning will produce a strong current, and it will stop when it meets resistance. But because the tree is not a good conductor, the resistance of the trunk will be greater, so the lightning current will stop pouring directly from the tree to the earth. When people encounter lightning in a thunderstorm and take shelter under a tree, when the lightning from this big tree comes down and reaches people's heads, an arc flashes down, then hits people's heads, and then pours into the ground through the human body, causing lightning disasters. Therefore, if people take shelter from the rain under trees, they are easily struck by lightning. Moreover, when it rains, there is also intermittent rain under the tree. Everyone knows that water can also be charged. So don't hide under the tree in a thunderstorm, so there is a great chance of being hit by lightning.

Don't hide under a tree during a thunderstorm, and don't make a phone call or answer a phone call during a thunderstorm and lightning. Unplug the telephone line. The mobile phone can be used normally, but generally try not to answer the phone outdoors or indoors near the window when it thunders.
