The currents of "El Niño": Transforming the Earth's climate

Ms Smith because protest in Santiago because Chile is flooded more than normal. In a fish store in the center of Lima, the price of certain species of fish is doubled. In Rosario Stock Exchange, in turn, triggers the future value of some cereal because this year it is estimated that the harvest will not meet expectations. Is it possible perhaps that these events are connected? Well, could be. The phenomenon "El Niño" rose water temperature in the American Pacific coasts and climate, overcome by so great alteration, succumbs to the chaos.
El Niño is a cyclical climate phenomenon erratically is a change in the movement patterns of ocean currents in
the tropics causing consequently global havoc due to heavy rains, affecting mainly South America, both in the Atlantic coast and in the Pacific. The scientific name for the phenomenon El Niño Southern Oscillation (El Niño-Southern Oscillation, ENSO, for its acronym in English). Phenomenon is explained by the Earth's rotation movement.
During El Niño, the trade winds weaken or stop blowing, the sea temperature maximum shifts to the current system Chilean-Peruvian (perceptible increase in water temperature) which is relatively cool, and the minimum sea temperature moves to Southeast Asia. This causes increased air pressure in Southeast Asia and South America decreased. All this change occurs at an interval of six months, approximately from June to November, producing strong alterations in climate.
The consequences of this climatic phenomenon leads to random regions of South America:
- Losses fishing certain species and increased in others.
- Intense cloud formation generated in the intertropical convergence zone.
- Wet periods.
- Low atmospheric pressure.
- Agricultural losses.
