The climate is abnormal this year. Why are there floods in many places?

? The main reason is the greenhouse effect caused by the massive emission of carbon dioxide and the influence of El Nino warm current. Recently, because of the COVID-19 epidemic, everyone's influence on 2020 is very bad. It happened at the beginning of the new year. Later, some disasters often occurred in many areas.

? Just one year before the outbreak of COVID-19, that is, in the summer of 20 19, a drought occurred in the north and south of China. Have you noticed that the winter of this epidemic is not cold? The so-called warm winter phenomenon appeared. I read some reports, and the general reason is the atmospheric circulation. In other words, it refers to a large-scale atmospheric operation phenomenon. Generally speaking, it is a global sport.

? El Nino warm current is also the cause of many weather disasters this time. This is an atmospheric phenomenon in the Pacific Ocean. Mainly in the southern hemisphere. The formation of this warm current is related to the rise of SST in the Pacific Ocean. Just today, May 8, the National Climate Center monitored this El Niñ o warm current. It will also appear this year, not very strong, but it will also have an impact on the precipitation this summer.

? This flood phenomenon is often due to the increase of precipitation, the current urbanization phenomenon and the modernization of agriculture, which all consume a lot of energy and emit a lot of waste gas. Air pollution is one thing, and atmospheric warming is another. Because we are constantly generating heat, many exhaust gases are very hot, which has a great influence on the temperature of the whole atmosphere.

? There are also deforestation and abuse of pesticides and herbicides. Leading to soil quality deterioration and soil erosion. This has led to the siltation of many rivers, and the water storage and drainage capacity has been greatly reduced. This has led to frequent floods this year.
