Most Arctic Lightning Is Bad News for the World


The Arctic is not extreme heat. That is why, too heat. It’s a little warm very fast like the rest of the world, which is causing bad loops that speed up change. For example, ice looks better than soil, so when it melts, the region absorbs more solar energy. The darker the plants are growth in the northern hemisphere, also heats the sun’s heat. And when the ice is shaken, it releases large amounts of greenhouse gases, which also warm the climate.

The Arctic Ocean is so awesome that lightning – the coldest winter in the tropics – is now boycott near the North Pole. And according to a new estimate, the electric current in the region is getting worse. By the end of this century, the number of lightning flashes across the Arctic can double, which can lead to dramatic shocks – wildfires and extreme temperatures. “The Arctic is a rapidly changing region, and this is part of a process that I’m not sure has received much interest, but it’s very important,” said UCLA meteorologist Daniel Swain, who did not participate in the study.

To make thunder you need a lot of heat. When the sun warms the soil, hot air and moisture rise in the atmosphere. Immediately, the cold air waits. This creates a circular cloud known as a deep cloud, which also generates electricity that grows into lightning.

It is not uncommon in tropical areas, where temperatures are high around the equator, but the Arctic must be cool enough to prevent high temperatures. Not anymore, it seems. “With the heat of the weather, you’ll have more energy to push the air off the ground,” says UC climate expert Irvine Yang Chen, senior author on a new topic. paper inside Global warming explaining images. “Also because the air is warmer, it can store a lot of water vapor.”

Put these together and you have a huge, powerful hurricane traveling 100 miles from the North Pole. (Scientists can detect their strike in remote areas with global radio transmitters: When the cage hits the ground, it turns like a radio, and blows the flag.) And where there is lightning, you can light fires, especially when the Arctic warms and dries up. “People Temperature 2020 in Russia’s Arctic Ocean shows how, even at higher altitudes, temperatures can set in motion that could lead to more and more severe fires, “said Isla Myers-Smith, an environmental scientist at the University of Edinburgh who studies the area but has not participated in the new project. “A many places have been burned in the 2020 fire season in Russia. ”
