The location of Seoul, South Korea is similar to that of Northeast China on the earth, so the weather in Seoul, South Korea is similar to that in North China. Stairs in the residential area are frozen, mainly because the stairs are outside. In the case of exposure, the degree of cold outside is relatively high, and the surrounding environment is very cold when the cold wave strikes recently. So why on earth are they frozen?

1. What is a cold wave? Why are the stairs frozen? In fact, many people are curious about the cold wave, because people only know cold air, which is actually similar to cold air. The cold wave is the highest realm of cold air. If a cold wave strikes, it means that extremely cold weather is coming. What is the cause of the cold wave? In the north, including South Korea, which belongs to the southeast of Eurasia, the cold wave affecting China or South Korea is actually influenced by the Arctic region. As we all know, the Arctic is very cold, especially because of the lack of sunshine and short time. In the case of snow all the year round in the Arctic, the winter sunshine will directly cross the equator and reach the northernmost part of the southern hemisphere, so the Arctic cold will be strengthened. When the cold air gathers to a certain extent, it will produce cold wave weather, so there are more and more cold waves, which will spread to the north. At present, it is also in the north of South Korea or China, and the Arctic is particularly cold this year. Because the density of the atmosphere has greatly increased, the cold air has been sinking and the air pressure has been increasing, so the air pressure is also very cold after such cold air reaches the north, so this year's cold wave is also very serious.

Second, what should I do if the stairs freeze? Be sure to thaw in time, so when the stairs freeze, thaw in time, because many people will pass by and it will be slippery. If they are frozen, someone is likely to get hurt when they pass by. So, if the stairs are frozen, they can be thawed with hot water. Also, we should pay attention to leave the stairs indoors as much as possible, and put a sign near the stairs that is easy to slip to prevent someone from slipping and being injured because of the freezing of the stairs.

Don't worry about the stairs being frozen, because with the arrival of summer, the cold wave will gradually end and the temperature will gradually rise, so it's nothing to freeze the stairs.
