Starting in mid-May, the south has entered the rainy season in an all-round way, thunderstorms frequently occur, and lightning strikes are also on the rise. According to experts from the Yunnan Lightning Protection Center, the average annual number of thunderstorm days in most parts of the province is more than 70 days. May-October of the rainy season is the season of high occurrence of lightning disasters. The objects of lightning hazards are people, and tall buildings and electronic equipment.
With the popularity of modern outdoor tourism, safety issues have also become the focus of tourists’ travel. Beware of lightning strikes is a noteworthy item. It is reported that some famous mountain scenic spots in our country have some accidents that tourists are struck by lightning every year. , I would like to remind tourists who like outdoor tourism to pay special attention to preventing lightning strikes when they are active in high terrain and wilderness areas. According to meteorological experts, whether it is a dark cloud or a bright sunny day, the atmospheric electric field always exists. Affected by the geographical environment, mountainous areas, river banks, lakes and other places are high-incidence areas of lightning. The lightning disaster is mainly formed by the discharge process between the cloud and the ground. The lightning point is selective. It basically follows the law of tip discharge. The higher the ground and the better the electrical conductivity, the easier it is to become a lightning strike. point.
Experts remind: When a thunderstorm occurs, do not take shelter from the rain near the power source, big trees and poles, stay away from trees, masts and water, and look for low-lying areas with your feet together to take squatting. Sitting posture, try to reduce the height of the body; do not carry metal frame umbrellas on your shoulders in open spaces; do not use or touch electrical equipment during thunderstorms; do not get too close to the outer walls of tall buildings (generally keep a distance of more than 3 meters). ); avoid places with water such as lakes, ponds, and isolated buildings that are vulnerable to lightning strikes such as thatched huts, huts, and pavilions, and avoid lightning strikes to the greatest extent possible.
