Nearly 1,000 people each year resulting in death due to lightning.

World Scientific reports [tech.] Message: Event Playback: summer, the period of high lightning activity also will come. .May 23, Kai County, Chongqing, a school was struck by lightning, killing seven students were killed and 40 injured. .On the same day, two more in the city Liangping outdoor killed by lightning while walking the fields. .June 4, Guangdong Province, a farm shed Luoding lightning strike occurred, killing five people were killed and 3 wounded. .June 11, Fujian Meteorological Bureau announced that the province from January to May this year, a significant lightning disasters caused 9 deaths and 13 injured. .<P Align=center> </ P> <P> Qie, a research fellow at Institute of Atmospheric Physics, mainly engaged in the physics of atmospheric electricity and lightning, the current members of the International Commission on Atmospheric Electricity, American Geophysical Society, Institute of Atmospheric Physics, Chinese Meteorological .deputy director of the Committee of the Tenth CPPCC National Committee. .</ P> <P> "Science Times": this time been reported lightning strike, giving the impression that lightning disasters in China quite frequently, is that so? .</ P> <P> Qie: report more relevant, first, the channels of information dissemination is now more clear, the statistical work of the disaster is more standardized than in the past, more accurate. .On the other hand, lightning is indeed a more serious disaster, the National Weather Service statistics show that nearly 1,000 people in China every year killed by lightning, lightning caused a direct economic loss of nearly 10 billion; harmful levels has become a lightning .after heavy rain floods, the third largest geological disasters of meteorological disasters. .</ P> <P> course, the statistics may not fully. .For example, in many places in rural areas, "by lightning" was also superstitiously regarded as "retribution", and place no one willing to say. .</ P> <P> "Science Times": Generally speaking, being struck by lightning is a small probability event, did not think the "top" so higher. .</ P> <P> Qie: This ranking is only in respect of meteorological disasters in terms of. .Although a direct lightning hit a fixed target probability is relatively small, but in our country, a very wide range of lightning disaster. .Southeast region, including Hainan, Guangdong and Fujian, the coastal areas, even Guizhou, Yunnan, Chongqing and Sichuan are the high incidence of lightning; many mountainous areas are prone areas; even some low-incidence areas of lightning activity, but also some of the high point of the distribution of .such as the northeast and northwest parts of the mountains and forests and so on. .Globally, 100 times per second, lightning is about to occur, although every time lightning strike events are low probability events, but due to wide distribution, so from the perspective of national or global may become a high-probability event .So thunder and lightning, also known as a high-impact weather events. .</ P> <P> lightning can be divided into two types of traditional cloud-to disasters. .If lightning hit the forest, oil depots, etc., causing a fire; hit the building causing damage; hit people, animals and other casualties. .Another indirect lightning disasters. .</ P> <P> With the development of technology and modernization, electronic equipment and electronic devices are widely used in our production and all areas of life, and these electronic devices and components are generally more sensitive to electromagnetic interference, because .lightning occurs, will produce a strong electromagnetic radiation, if it exceeds their tolerance, it will damage them, causing paralysis of electronic systems. .In the electronic age, indirect economic losses caused by lightning disasters is growing. .Relative casualties, may be the indirect lightning injury news was also less concern. .</ P>.
