The Yangtze River Daily Da Wuhan client Da Wuhan client July 19th. The strong weather was coming. Hubei issued a warning of heavy rain and thunder and lightning. The Wuhan Meteorological Observatory issued a lightning yellow warning for two consecutive days. Lightning disasters have been listed as one of the ten most serious natural disasters by relevant United Nations. How to prevent lightning? A reporter from the Yangtze River Daily interviewed Zhu Chuanlin, director of the Lightning Power Protection Products Inspection Laboratory of Hubei Province on the 19th.

The key to lightning protection: hiding indoors, low stations, small steps, far from metal body

Zhu Chuanlin introduced that thunder and lightning is a fierce discharge phenomenon in the atmosphere, and usually appears in the condition of thunderstorms (accumulated rain clouds). Lightning can be divided into clouds, cloud lightning, cloud lightning and cloud ground lightning according to the location of it. When discharging clouds to ground, it will form a severe thermal effect, electrical effect, mechanical effect, and electromagnetic effect, so it will be greatly destructive.

When encountering lightning weather, if the time interval between thunder and seeing lightning is getting shorter and shorter, it means that the lightning is getting closer and closer; if the lightning is quickly thundered after lightning, it means that the lightning is nearby. He summarized "18 tricks for lightning protection" to remind the public that when the weather is coming, it should immediately stop outdoor activities or homework, find a place to avoid safety, close the doors and windows in the room, and do not avoid thunderstorms under the big trees; thunder and lightning is easy Hit the objects with higher altitude, such as mountain tops, high -rise buildings, roofs, electric poles, chimneys, etc., and the open area of ​​the open area is also the object of thunder and lightning. In the thunderstorm, you should stay away from these objects and look for low -lying places and squat and feet your feet. Do not run closer. Outdoor lightning protection must follow the two principles: first, the human body should try to be in a lower position to reduce the risk of direct lightning strikes; the other is that the distance between the human body should be as small as possible to reduce the risk of "step voltage". Do not use umbrellas and mobile phones in the wild in thunderstorms. Be sure to stay away from the metal body. Metal objects have a thunderstorm effect. If the rainy weather is just in the car, the door and window should be closed immediately. Do not get off the car. It is best not to start the car. He particularly reminded that the thunderstorm weather cable may be charged, which is very dangerous, and it is also dangerous to call a fixed phone. There have been any cases of electromagnetic induction, and some citizens picked up a case of fixed telephone and lightning strikes. He also emphasized that some people think that the human body will have lightning with lightning after a lightning strike, which is a wrong cognition. Lightning currents pass through the human body and spread into the earth. The human body is not charged and is not dangerous. Therefore, the wounded of the lightning strike should be rescued in a timely manner, and the 120 emergency phone call should be called to ask professional medical staff for rescue.

The establishment of a lightning monitoring and early warning system in our province will push the trend of lightning Thunder Cloud to professional users

Zhu Chuanlin said that the central urban area is more crowded, and there are many high -rise buildings. According to national standards, the corresponding lightning protection facilities are installed in the first, second, and third types of lightning protection buildings, and entrusted to the lightning protection service agency with detection qualifications for a lightning protection annual inspection inspection Among them, explosion and fire hazardous places are tested every six months to reduce the minesweeper prevention hazards of building (structure). In comparison, the risk of thunder and electricity in Yuancheng District is larger than that of the central urban area. At present, our province has built a variety of lightning detection equipment, including 19 three -dimensional lightning positioning instruments and radar, atmospheric electric field instruments and other equipment. Among them, nine cities such as Wuhan, Macheng, and Suizhou have radar, and there are 30 high electric field instruments in Wuhan. The data is uploaded to the Lightning Monitoring and Early Warning Software System through the server of the Provincial Meteorological Bureau to push to professional users. "Lightning early warning is a very complicated system. The parameters change with the season and climate system. The algorithm is complicated, and the algorithm needs to be continuously optimized." Zhu Chuanlin said that the lightning monitoring and early warning system is still being upgraded. To launch a client custom software, you can directly see the mobile trend of lightning and thunder clouds in the device terminal, and take better measures to prevent thunder and lightning hazards.
