El Nino phenomenon was first found along the coast of Peru. Because it often occurs around Christmas, local fishermen named it "El Nino", which means "holy baby".
Nowadays, El Ni ñ o has spread all over the central and eastern Atlantic and Pacific oceans, often raising the surface water temperature by more than 3 ℃. The rise of sea water temperature caused a large number of plankton in the water, and the fishery production was hit. In addition, El Ni ñ o phenomenon will also cause floods in the original dry and rainless places, while the usually rainy places are prone to long-term drought and little rain. For example, in Ecuador and the equatorial Pacific region, abnormal floods or droughts will occur due to the El Ni ñ o phenomenon. El Ni ñ o has caused severe drought in many areas.
