El Nino is a periodic natural phenomenon, which occurs about once every seven years. Through the study of global climate, scientists believe that El Nino is not an isolated natural phenomenon, but an aspect of global climate anomaly. In recent months, many global climate prediction institutions have increased the probability of El Ni? o. According to the data of the US Federal Government Climate Prediction Center, in the past month, the probability of El Ni? o weather phenomenon has greatly increased this year, and the probability of El Ni? o phenomenon in summer has exceeded 65%. The World Meteorological Organization also issued a communique a few days ago, saying that in view of the fact that the seawater temperature in the equatorial Pacific has reached the precursor level of El Ni? o, El Ni? o may occur in the middle of this year.
