The El Niño warm current disrupted the normal ocean current circulation in the South Pacific, and then disrupted the original distribution regularity of the global pressure and wind belts, resulting in serious climate disasters. For example, the coastal areas of Peru in western South America and northern Chile were originally very dry tropical desert climate areas. Due to the impact of the El Nino warm current, terrible natural disasters such as continuous rainstorms, flooding, and mudslides were often formed; the Peruvian fishing grounds were affected by El Nino. The warm current prevents the flooding of the cold sea water, causing a large number of plankton in the deep sea to be unable to be transported to the sea surface through the flooding water, causing a large number of fish to die due to lack of erbium. The tropical rain forests of Indonesia, Ilian Island, and northern Australia experienced severe droughts due to the occurrence of the El Niño Warm Current which disrupted the normal water cycle in the South Pacific.
