What influence does La Nina have on China?

1, La Nina phenomenon caused the phenomenon of "Leng Xia fever in winter" and "drought in the south and waterlogging in the north" in China. 2. La Nina phenomenon causes a wide range of windy weather, long-lasting low temperature weather and rain and snow weather. 3. La Nina will cause persistent windy weather in northern China, and strong winds will immediately form sandstorms.

La Nina phenomenon is an abnormal cooling of seawater in the central and eastern Pacific Ocean. The southeast wind blows the seawater heated by the sun to the western part of the Pacific Ocean, causing the sea level in the western part to rise by nearly 60 cm compared with that in the eastern part, the sea temperature in the western part to increase, the air pressure to decrease, the accumulation of wet air to form typhoons and tropical storms, and the bottom seawater in the eastern part to flow backward, resulting in the cooling of the sea water in the eastern part of the Pacific Ocean.

La Nina means "lani _ a" in Spanish-"little girl, saint". Contrary to the El Ni? o phenomenon, it is also called "anti-El Ni? o" or "cold event". It refers to the abnormal drop of water temperature in the eastern Pacific near the equator, which is characterized by obvious cooling in the eastern Pacific, accompanied by global climate chaos, and always appears after El Ni? o phenomenon.

La Nina often appears alternately with El Nino, but the frequency is lower than El Nino. When La Nina phenomenon appears, Leng Xia fever in winter is prone to occur in China, and the number of tropical cyclones landing in China is more than normal, resulting in the phenomenon of "drought in the south and waterlogging in the north"; Indonesia, eastern Australia, northeastern Brazil and other places have more rainfall; The equatorial regions of Africa and the southeastern United States are prone to drought.
