What's wrong with the heavy snow? Cold low pressure + hot sea 'wrong meeting'

[Anchor]
The unusual snow bomb in the central part of the country was caused by a cold low pressure and a meeting of the hot sea.

I'm even more worried about the possibility of such unusual heavy snow this winter.

Reporter Kim Min-kyung's report.

Snow clouds in the shape of long bands like the rainy season were created in the western sea.

Overnight, snow bombs continued to fall along this passageway in parts of Gyeonggi Province and Seoul.

It is similar to the clouds that occur during the rainy season in summer.

An unusual November snow bomb that poured into the Midwest, a cold low pressure in the upper atmosphere and a "wrong meeting" of hot seas were the cause.

As the flow of the upper atmosphere, so-called blocking, stagnated, low pressure rotated in place and continued to send cold air below minus 30 degrees Celsius, and

The cold air passed through the relatively hot West Sea.

Currently, the temperature in the West Sea is about 15 degrees Celsius and 2 degrees higher than usual.

The larger the temperature difference, the stronger the clouds develop, and as the cold air passed through the warm West Sea, it continued to receive water vapor and created a powerful snow cloud, pouring out tremendous snow.

[Kong Sang-min / Meteorological Agency forecaster: As the low pressure in Juri stagnated, we were able to maintain the 'b'-shaped barometer. As the cold air passed over the warm sea, it could be said that a lot of snow fell due to the continuous inflow of strong rain clouds caused by large sea vehicles.]

Some weather experts are concerned that these disaster-level weather events are likely to become more frequent this winter.

[Ko Ki-jin / YTN Disaster Advisory Committee, visiting professor at Chungbuk National University] These days, it's called the new normal. You can't interpret the weather by the old standards. As the earth heats up as a whole, it is now difficult to predict which direction it will change....]

Record heavy snow,
that came even before full-fledged winter began, as if foreshadowing a severe winter.
In addition to preparing for disasters amid the climate crisis, active action is urgently needed to prevent a hotter planet.
