The El Nino warm current destroyed the normal ocean current circulation circle in the South Pacific, and then disrupted the original distribution law of the global pressure zone and wind zone, causing serious climate disasters. For example, the coastal areas of Peru in the west of South America and Chile in the north used to be very dry tropical desert climates. Due to the influence of El Nino warm current, terrible natural disasters such as continuous rainstorm, flood and debris flow often occur.

The upwelling of cold water was inhibited by the El Ni? o warm current in Peruvian fishing grounds, which caused a large number of plankton in the deep sea to be unable to be transported to the sea surface through the upwelling seawater, resulting in a large number of fish deaths due to the lack of erbium. Due to the appearance of the El Ni? o warm current, the normal water circulation law in the South Pacific was destroyed, and the tropical rain forest areas in Indonesia, Irian Island and northern Australia suffered severe drought.

Extended data

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.
