The impact of the El Ni? o phenomenon largely depends on the development in the next few months. Studies show that when the sea surface temperature warms, the atmosphere over the ocean will also warm, thus affecting the whole atmospheric circulation. When the El Ni? o phenomenon occurs, it will often have a certain impact on the climate in the middle and high latitudes of the northern hemisphere from late autumn to winter. Ren Fumin said that according to the latest meteorological data, the current surface water temperature in the Pacific Ocean is about 65,438 0.3℃ higher than the average water temperature. Judging from the current atmospheric circulation situation, the warmer sea water in the equatorial Middle East and Pacific Ocean will still be maintained and will continue to affect the normal distribution of atmospheric circulation. In this case, experts predict that under the influence of El Ni? o, there may be a "warm winter" in China, and the arrival of a new El Ni? o phenomenon is really worrying. It is both a result and a bridge. On the whole, the appearance of El Nino is not a good thing. Because in the context of global warming, the appearance of El Ni? o may make extreme weather and climate events occur more frequently and with greater intensity, which will aggravate climate change and global economic recession, and economic recession will surely harm mankind.

El Nino phenomenon transmits the abnormal signals of the atmosphere and ocean in tropical areas to other tropical areas and middle and high latitudes through the action of atmospheric circulation, and its influence is global. Since entering the El Ni? o state, global weather, ocean conditions and marine fisheries have been greatly affected. Whenever El Nino appears, some fish along the coast of Peru have to migrate because of the rising temperature, but others are attracted. The number of fish, scallops and shrimp along the southern coast of Peru has greatly increased, and fishermen's nets have not been lost, and the harvest is much better than usual; At the same time, El Ni? o brought a lot of rainfall to the desert areas in northern Ecuador and Peru, and also turned this barren desert into a grassland densely covered with lakes. El Nino has also led to a large-scale reduction of some cash crops such as soybeans, cocoa, coffee and olives, which is not a bad thing for the overheated international market. The rising price of soybean, the firm price of soybean oil and the promising export prospects of coffee and cocoa can limit the vicious competition among countries to continuously increase production and depress prices, and make the futures price in the international market in a more reasonable state. In addition, the types of El Ni? o events are complex, and different types of El Ni? o events have different impacts on the climate. Under the background of climate warming, the climate effect of El Ni? o event has stronger uncertainty characteristics. Therefore, the appearance of El Nino event not only increases the possibility of climate anomaly, but also increases the complexity and uncertainty of climate prediction.

El Nino is a double-edged sword. On the positive side, El Nino phenomenon helps to restrain typhoon activities in the northwest Pacific. In the United States, El Ni? o can bring favorable winter precipitation to the arid southwest, reduce winter snowstorms in the north and reduce the risk of forest fires in Florida. Under normal circumstances, in the winter of the year when the El Ni? o event occurred, only considering the impact of the El Ni? o event, the precipitation in the south of the Yangtze River in China tends to be more, and the precipitation in eastern Huanghuai, Jiangnan, South China, Yunnan, Gansu Hexi and other places may be more. The following spring, affected by the El Ni? o event, except for the cold in central and western Xinjiang, southern Yunnan and southwestern Guangxi, most parts of the country were mainly warm.
