<Anchor> As the



sweltering heat continues, in the case of Seoul, this month is expected to be recorded as the second hottest July ever.



In addition to the Korean Peninsula, there are recent extreme weather events such as extreme heat and heavy rains in various parts of the world, and reporter Jung Gu-hee pointed out the reason.

The cows in the barn rarely leave under the sprayer that spews cool water.



[Cheongju Livestock Farm: People are so hot, but cows are not really hairy animals. I guess my appetite has dropped a lot.] The



high temperature is extreme in the central region, especially in Seoul.



The average high temperature in July in Seoul, which has been hot for 14 days, was 32 degrees, the second highest after 1994.



[Yoon Se-in / Mapo-gu, Seoul: (visited) The air conditioner was turned off for a while due to the construction of the store, so I ran out, to another store. It's so hot that I can't live.] The



mid-latitude regions are suffering from abnormal climates to the extent that the World Meteorological Organization calls it 'extreme summer'.



In Canada and the western United States, wildfires continued in the heat of 50 degrees Celsius, and Western Europe, including Germany and Belgium, and parts of China and Western Europe were flooded with record heavy rains.




The cause of extreme weather is global warming.



As the temperature rises significantly as far as Siberia, an abnormality in the air flow has occurred.



In mid-latitudes including Korea, a strong jet stream flows over the sky and circulates the atmosphere.



This jet stream is created between cold and warm air, and as it warms to higher latitudes, the airflow point rises further north.



As a result, the atmosphere is stagnant in the mid-latitudes, and hot places are constantly hot, and in places where it rains, heavy rain continues.



[Kim Baek-min/Professor of Environmental Atmospheric Sciences, Pukyong National University: Normally, the core (center) of the jet stream is located around 40-50 degrees north latitude. The jet stream will be weakened.] The



Meteorological Administration predicted that the temperature will drop slightly over the weekend with occasional rain, but the high humidity will make the perceived temperature exceed the heat wave standard of 33 degrees.
