What is cold air? Where does the cold air come from?
In fact, cold air usually comes from Siberia or the Arctic Ocean. When watching the weather forecast, we often hear the host say when introducing cold air. There is a cold air coming from Siberia? This is actually the source of cold air. Siberia and the Arctic Ocean are very cold areas, where the temperature can generally reach tens of degrees below zero.
If cold air comes from Siberia, it will cause the temperature in the area where it passes to drop sharply, and the temperature difference can reach more than ten degrees. This cooling rate is very scary, especially in winter. You may feel the feeling of winter overnight in spring, and cold air will be accompanied by weather changes such as rainfall and even snowfall.
If it is more serious, it is likely that there will be severe weather such as hail, especially now that the greenhouse effect is serious and some strange climate changes often occur. There will probably be hail when cold air comes in June. However, the intensity of cold air is different every time, sometimes it is very strong and sometimes it is very weak, so the impact on the areas affected by cold air is different.
Moreover, cold air is the same as waves. It keeps moving and has its own moving path, which may be affected by the wind direction, so the path of cold air arrival is different every time. No one knows which way the cold air will choose. So sometimes when cold air comes, it will be more serious in the north and sometimes more serious in the south, which is caused by different paths.
When the cold air comes, there is no doubt that the temperature will definitely drop a lot, so in this case, you must pay attention to keep warm in advance.
