Disaster caused by foehn effect

Burning wind has many hazards. It often dries up fruit trees and crops, reduces production, spreads fires in forests and villages and causes losses. /kloc-in the 0/9th century, there were several famous big fires on the northern slope of the Alps, all of which occurred during the prevailing period of foehn. Foehn can melt a lot of snow in mountain areas and cause floods in the upper reaches of the valley; Sometimes it can lead to avalanches. If the terrain is suitable, strong wind burning can cause local wind disasters, blow away the roofs of rural houses in mountainous areas, blow down crops, uproot trees, endanger forests, and even cause ship accidents on the lake.

165438+1October 14 night, foehn wind formed a strong storm in some parts of Austria, attacking all farmland and villages at the speed of 160 km per hour. Where the burning storm passed, the roofs of hundreds of houses were blown away or crushed by the wind, many trees were uprooted or broken, power supply and telephone communication were interrupted, and road and railway traffic was blocked. Two people died and millions of euros were lost.

On May 1 1, 2004, there was a foehn in Taidong, Taiwan Province Province, and the high temperature of 40.2 degrees Celsius set a century-old record in Taidong. At noon that day 12: 57, a strong burning wind suddenly blew in the downtown area of Taitung, and the indoor and outdoor temperatures rose rapidly like an oven. At 13: 00 and 14: 00, the temperature soared to 40.2 degrees Celsius, making the local residents miserable. Some people turned on the air conditioner and hid in the house. Some people took their children to the clear stream in the suburbs to enjoy the cool. Farmers are even more bitter, because they are most afraid that hot leaves and tea trees will wither slowly in the strong burning wind.

In high mountain areas, burning wind can also lead to melting snow, flooding upstream valleys and sometimes causing avalanches.

In addition, when windy weather occurs, many people will have uncomfortable symptoms, such as fatigue, depression, headache, bad temper, palpitation and edema. Medical meteorologists believe that this is caused by the dry heat characteristics of foehn and the influence of changes in atmospheric electrical characteristics on human body.
