By scientific definition, El Nino is equivalent to an alteration of water temperature on the shores of the Pacific. Its consequences, however, makes it one of the most important weather phenomena produced in the ocean and atmosphere. In Peru, this manifests itself as an ocean current that breaks the northwest corner of the territory of Peru, producing a significant change martino and coastal ecosystem of this part of the coastline: rains and floods in the north and drought and frost in surandino Altiplano.
In general, one can say that the occurrence of the El Ni o phenomenon is due to a change in trade winds over the ocean. These winds blow from a permanent soroeste in the tropical zone, dragging the cold waters of the Peruvian current that way. However, every few years, for unknown reasons, these winds are suffering a significant modification: dismunuyen speed up and change direction, blowing from the northeast and then causing a change in ocean currents that bring warm water to typical tropical the north coast of the country.
Depending on the intensity of change in the winds, the warm currents can reach the central coast, or in exceptional situations to the extreme southern Peru and northern Chile. Hence explaining the presence of marine species typical of tropical coastal zones Limena as swordfish, the parrot, the prawns and the mere (and the consequent removal of the species typical of cold waters, such as anchovy, the mackerel and sardines). With visitors arriving seamen also waterfowl as the frigate and the blue-footed booby, following the shoals that, confused, still waters that provide the conditions for survival.
According to studies, the phenomenon of El Nino is a natural characteristic of recurrent but not periodic. This means that presents with different magnitudes at intervals that vary between 3 and 10 years. In general, the intensity of manor or “good kids” happen every 3 or 4 years, while the “bad kids” or high intensity happen every 8 to 10 years.
Occasionally, phenomena like the size that devastated the north coast of Peru in 1982-1983, occur only (and thankfully) every 80 to 100 years. This incident, which devastated much of the coastal villages of the country affect the coasts of Ecuador and Chile, and one way or another, the climate worldwide.
NS the most visible effects of this phenomenon are the formation of large cloud fronts that produce heavy rainfall in areas where there are usually no more than garu the huaicos or landslides, as well as erosion, often accompanied the rains, closing the cycle devastation that the child is leaving in its wake.
However, not all consequences of this climate megaalteracion bad or harmful to humans. One such example is the extraordinary appearance of vegetation in desert areas and depopulation of the northern coast of Peru. this phenomenon as natural regeneration, has a potential for the development of marginalized areas of the country as large as the dimensions of the child in question himself.
The name, El Nino (with whom he is known around the world), goes back to the northern port of Paita. Artisanal fishermen have always been well known to a stream of warm water that is presented each year to reach this area in December. By association, the name of the current is related to the arrival of the child God, ie, on the eve of Christmas.
Past, the importance of this trend for men was that of sea water, but warm enough that they used to bathe their coasts the rest of the year, the fish away from the coast, thus terminating the annual fishing season the northern coast of Peru. It was therefore the beginning of time off and be with the family, repairing nets and boats. It was time to await the arrival of El Nino.
