Why does it cause drought? Where did the water go?

Because La Nina phenomenon, subtropical high and global warming caused this year's summer heat, the summer heat led to drought, and the water after drought evaporated into the air and finally came down in the form of rain.

I remember that when I was a child, people living in the middle and lower reaches of the Yangtze River rarely really encountered drought, and only some water-deficient areas could be dry in the dry season. But this year, Chongqing, Sichuan, Hubei, Jiangxi, Jiangsu and other provinces in the middle and lower reaches of the Yangtze River have all suffered a once-in-a-century drought.

Being in Hubei, I actually know the relevant situation every day. From July to August, many people fought in the front line of drought relief. Even so, rice and corn withered and died, which has to be said to reflect the deterioration of the environment.

It is understood that La Nina phenomenon is mainly a phenomenon that meteorologists refer to the continuous and abnormal cooling of sea surface temperature in the eastern and central equatorial Pacific Ocean, also known as anti-El Nino.

Subtropical high is a kind of situation along the ocean coast and an energy transmission, which will affect the climate environment in inland areas in summer.

The pollution of atmospheric environment, the deterioration of marine environment and the sharp increase of population have led to global warming. For example, the plastic bag we commonly use is a pollution and cannot be degraded. A lot of garbage will run from our hands to the trash can, to the garbage transfer station and finally to the landfill. Perhaps a lot of garbage will be integrated into nature over time, but plastics will not be degraded in the following decades and hundreds of years and become garbage in the living environment.

I once saw a short video in which a caring person pulled out a straw from the nose of a big turtle and found the plastic bags, food scraps, wires and discarded daily necessities they had eaten by mistake from the bodies of various marine creatures that washed up on the beach. Speaking of where these things came from, I once walked by the river and found rubbish, such as plastic water bottles, snack bags, iron filings and so on. Occasionally seen on the beach, all these things finally affect the sea.

For example, burning wheat straw in rural areas, burning fossil fuels such as oil and coal in cities, or cutting down forests and burning them will produce a lot of carbon dioxide, that is, greenhouse gases, which will eventually affect global warming.

In our life, the water in rivers, lakes and seas will not disappear because of the extreme heat. Water is still on the earth, and they will all gather in the air, and finally come down in the form of rain, and finally form natural disasters such as storms and floods.

Last year, the floods in Henan province and some cities in the middle and lower reaches of the Yangtze River in previous years were all caused by excessive evaporation, which poured down in one breath and eventually led to many places becoming Zeguo.

People have paid more and more attention to the environment of the earth. In our country, some people salvage garbage from rivers, treat smelly water and turn deserts into oases. Although this is an arduous task, I believe that these actions will ultimately benefit our future generations!
