What does El Nino mean? What kind of phenomenon does El Nino mean?
ELNINO means "El Nino" in Spanish. El Nino phenomenon is a phenomenon that guides the abnormal rise of the surface temperature of seawater in the cold ocean current area on the west coast of America 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 places that used to be dry and rainy, while places that are usually rainy are prone to long-term drought and lack of rain.
judging from the location of main rain belts in China from June to August, in 75% of El Nino years, summer rain belts are located in the Jiang and Huai river basins. Figuratively speaking, the low-frequency oscillation of atmospheric circulation in the tropics can be compared to the heartbeat in the tropics. The occurrence of El Niñ o event is like a heart attack in the tropics, which makes the regular low-frequency oscillation abnormal.
