10 El Nino - Essay prototypeIn normal years, ocean current flows to the north towards the Equator down the western coast of South America. The piddle on the ocean surface was world drawn away from the continent and to be replaced by bleak nutrient-rich water pushed upwards from the ocean depth. This process is known as upwelling. During this season, a good harvest is being anticipated by fishermen of the area. Further, colder weather is experienced by the people living in this area since the ocean surface is cold during this time.During El Nio year, the warm pool of water flows eastward until it spreads in the entire Pacific Ocean. For this reason, the cool water of the South American coast is replaced by warmer waters, indeed weakening the upwelling process (Trenberth 1997). In effect, the surface of the sea temperature rises beyond the normal range. This occurrence means toil near rainfall and eventual flooding in some South American countries and drought and very dry out season in Indonesia, Australia, the Philippines, Papua New Guinea, and Northeastern South America with altered patterns of equatorial storms in the tropical belt (Enfield n.d.). Global thawing is also a great contributor to this kind of phenomena.The coastal warming is being associated with a more widespread irregular ocean warming to the International Dateline and it is this Pacific basin-wide phenomenon that forms the link with strange global climate patterns. This component joined to El Nio is called the grey Oscillation (Trenberth 1997). ENSO (El Nino-Southern Oscillation) is the phenomenon where the atmosphere and ocean collaborates together. The El Nino phenomenon is the warm phase of ENSO, and its opposite, La Nia, the occurrence where chilling of the tropical Pacific takes place corresponds to the cold phase of ENSO.The El Nio, or ENSO for scientists, can be considered as a normal occurrence based on nature patterns studied by some scientists. But still, it greatly affec ts global climate
