Then, why is the day so cold and what the weather will be like in the future?



Reporter Jeong, First of all, I heard that this cold weather is an arctic cold wave. What is an arctic cold wave?



<Reporter>



There is a 'polar vortex', a very cold whirlwind that traps cold air in the Arctic.



However, as the Arctic warmed more and more due to global warming, as the ice melted, this cold whirlpool gradually began to lose its power.



Like ice cream melting, cold air from the Arctic comes down to mid-latitude regions such as Korea, Russia, and China.



The warming of the Arctic is the cause of the cold wave this time, and the Arctic is warming four times faster than the global average.

As the earth warms, it paradoxically creates such a cold, but in fact, this is not the first time.

But why is this year exceptionally colder?



<Reporter>



First, I think I should explain the characteristics of this cold wave.



Today (25th) the temperature in Seoul is minus 17.3 degrees, of course it is quite cold, but it is not in the top 10.



However, if you look at the temperature in Geoje Island, it fell to minus 10.4 degrees Celsius, the lowest ever observed.



It is quite unusual that the abnormal cold wave came to the southern region.



The cold wave became severe as the continental high pressure created in the interior of China approached Korea, and the clockwise continental high pressure brought the cold air from the north down to the south of Korea.

By the way, they say that this coldness turns into snow at night. How much does it snow?



<Reporter> The



problem is that the continental high pressure that brought down the arctic cold wave is moving.



As the continental high pressure gradually moves eastward with the westerly wind, the wind direction changes from northerly to westerly.



During the Lunar New Year holiday, a north wind blew and heavy snow poured over Jeju Island and Honam.



From tonight to tomorrow, 2 to 7 cm of snow is expected in the western region, especially in most parts of the country, and in particular, heavy snowfall of more than 10 cm is expected in Gyeonggi and the west coast of Chungcheong.

We must prepare for safety accidents.

So, is the cold easing a little now?



<Reporter>



First of all, tomorrow the temperature in Seoul will be -7 degrees Celsius higher than today, but on Saturday it will again reach -12 degrees Celsius, the level of a cold wave advisory.



A continental high pressure will occur again in China, so a northwesterly wind will blow again, and on Friday, it will snow in Chungcheong and Honam on this northwesterly wind. It looks like it will freeze, so be careful.
