What are the reasons why many countries in East Asia encounter extreme weather?

Recently, China, South Korea, Japan and other East Asian countries have been hit by heavy rainfall recently, and a large number of people have been affected. Korean experts believe that these extreme weather in East Asia is not unrelated to global warming.

Korean experts believe that the heavy rainfall in East Asia this year is closely related to the high temperature weather in the Arctic and Siberia. Claire Nalis, a spokeswoman for the World Meteorological Organization, said recently that the temperature in some parts of Siberia has risen above 30 degrees Celsius, and extreme weather of 38 degrees Celsius has even been recorded in the Arctic. According to the report, "The sharp rise in the Arctic temperature caused the Arctic ice and snow to melt, exposing the brown ground and absorbing sunlight. Affected by heated air, the cold air originally flowing from east to west turned north and south and moved to South Korea, China and Japan.

According to the analysis of the Korea Meteorological Agency, the butterfly effect brought by climate change in the Arctic and Siberia has an impact on East Asia such as South Korea, leading to heavy rainfall. The root cause of the recent rainstorm is global warming.

Global warming or aggravating rainstorm

It has been found that heavy rains and floods seem to be getting worse in recent years. A report in The New York Times, USA, in July pointed out that in recent years, more and more tropical cyclones and severe floods occurred in the monsoon season in South Asia. Why is this?

Although the formation factors of rainstorm are complex, many experts believe that global warming may aggravate the frequency and severity of rainstorm disasters. Climate warming will make sea level rise, sea water and air warm, and

Every time the temperature rises 1 degree Celsius, the air can hold 7% more water vapor. Therefore, in warmer conditions, the water vapor evaporated into the atmosphere will increase, and the water vapor content in the air will also increase accordingly.

According to the news website of the Climate Center, which specializes in climate change and energy issues, global warming caused by human factors has aggravated the most serious phenomenon of heavy precipitation. As the temperature rises, the amount of water evaporated in the oceans, lakes and soil increases, and the content of water vapor in the atmosphere increases. Therefore, when the rainstorm forms, more water vapor will condense into raindrops, which will provide "ammunition" for the raging rainstorm, and the subsequent floods may be more frequent and more harmful.

Rainstorms and floods occur frequently in many parts of Asia, and global warming may add fuel to the flames.
