There are constant claims on the Internet about "a once-in-a-hundred-year cold wave." What are the reasons for the frequent occurrence of extreme weather?
There are constant rumors on the Internet about "a once-in-a-hundred-year cold wave". The reason for the frequent occurrence of such extreme weather is Arctic sea ice.
This year’s winter can be said to be a very cold winter in recent years. Whether in northern cities or southern cities, they have been hit by cold air and have brought great trouble to people’s lives. There are even historical records where the temperature in many places has exceeded. Not only China is deeply affected by the cold air, but also Japan, South Korea and Singapore are all deeply affected by the cold air. There has been continuous heavy snowfall in Japan, water pipes have burst due to freezing in many places in South Korea, and even Singapore, which is on the edge of the equator, has experienced continuous heavy rain and cooling. So what is the reason for the frequent occurrence of such extreme weather? The most direct reason is the Arctic sea ice factor.
1. What is the Arctic sea ice factor?
We know that the Arctic is the coldest place, and it is also the production point of cold air. It is the home of cold air. In the Arctic, there is a polar vortex in the sky. This polar vortex has a huge Its function is to lock the cold air and prevent it from being released, just like our refrigerator, which locks in the cold air. However, with the many causes of global warming, the sea ice area has melted, causing the polar vortex's ability to weaken, so it cannot be fixed, and this cold air causes this cold air to float with the air flow. , so our winter is very cold.
2. The second cause of this extreme weather is the La Ni?a phenomenon.
Maybe some people should be very familiar with the La Ni?a phenomenon. The La Ni?a phenomenon refers to the abnormal cooling of the water in the central and eastern Pacific. That is, because of the influence of this phenomenon, all parts of the country have become very cold. La Ni?a The phenomenon caused the nearby seawater to become super cold, and the East Asian winter monsoon further strengthened the activity of cold air and became very frequent. As these cold air moved, it swept across the country and turned into cold wave cold air. , so this winter is really super cold.
3. In fact, the most direct cause of this extreme weather is global warming.
The weather is getting colder and colder. Many people have the illusion that the warming weather is an illusion. In fact, the weather is getting colder and colder because of the consequences of global warming. The greenhouse gas carbon dioxide increases so much every year that these greenhouse gases melt many icebergs, causing the temperature to get lower and lower. When all the icebergs melt, the world will become hotter and hotter. So protecting the environment is really important.
