◇Anchor> The Korea Meteorological Administration knew that the heavy snow forecast would continue to snow, but the amount of snow was a lot off this time, right?

◆ Reporter> Snowfall first forecast was more than 10cm. Making a forecast of more than 10cm is a warning that there will be more snow than a heavy snow warning. But the actual drop was over 20cm. More than 20cm means snow at the level of a heavy snow warning. However, unlike rain, snow is quite difficult to predict. If 1mm of rain falls, it's like 10 times and 1cm of snow falls. So 1mm of rain becomes 1cm of snow. 10mm of rain becomes 10cm of snow. This means that depending on how the snow piece passes through and how the snow cloud passes, the amount of snow can move back and forth by 5 to 10 cm. Therefore, the fact that the forecast of more than 10cm was given to the Korea Meteorological Administration to prepare for the big snow. Accordingly, I can tell you that we have come to the present situation by increasing the amount of snow.

◇Anchor> It is said that there was a large difference in the amount of snow in Seoul by region, but what is the reason for this phenomenon?

◆ Reporter> As a piece of snow came in, he may have sprayed snow and passed by. You can get off in the next area without getting off after developing a little more. So, if it's a snow cloud that contains a certain amount of snow, it moves around and sprinkles snow, and this time it's accompanied by wind. It is accompanied by strong winds. Think about it. Unlike the rain from above, when it snows, it flies. Because it is a situation where it flies according to the wind, just because snow clouds pass through this area, it doesn't snow from the area right below, but snow falls on the side. The stronger the wind, the more different the area where it falls, so there was a lot of difference even within Seoul, where the amount of snow was the same, and more snow fell in the east than in the west.
