El Nino means "El Nino" in Spanish. El Nino phenomenon is a phenomenon that leads to the abnormal rise of sea surface temperature in the cold ocean current area on the west coast of the United States around Christmas. It is like a "warm pool", which changes the atmospheric heating field through the change of surface temperature, and then brings changes to the weather in various places, causing floods in the original dry and rainy places, while the rainy places are prone to long-term drought and lack of rain.

From the position of main rain belts in China from June to August, 75% of the rain belts are located in the Yangtze River and Huaihe River basins in El Ni? o year and summer. Figuratively speaking, the low-frequency oscillation of tropical atmospheric circulation can be compared to tropical heartbeat. The occurrence of El Nino events is like a heart attack in the tropics, which makes the regular low-frequency oscillation abnormal.
