The climate phenomenon El Niño has important consequences for weather conditions in many parts of the world.
This year the phenomenon began in June or July and according to predictions by the World Meteorological Organization (WMO) will continue until the first quarter of 2010.
El Niño is characterized by a warming of surface temperatures and subsurface tropical Pacific Ocean and equatorial central and eastern areas.
was named in the nineteenth century by Peruvian fishermen who noticed its effects during Christmas. Occurs with a frequency that varies between two to five years.
The period of greatest intensity of El Niño occurred between the years 1997 and 1998 when water temperature increased 5 ° C, while this episode of the same is described with weak to moderate increases ranging from 0.5 º to 1 º C.
Among the areas most affected by the Child include the south and east Asia, where droughts will be more intense due to the weakening of the wet or monsoon winds. The drought in east Africa also will worsen. Furthermore, droughts will spread throughout the Australian plains while Europe will not be affected.
In Latin America, it is likely that this time the phenomenon does not cause the damage he left in 1997 without But countries in this region are alert to the reappearance of the phenomenon. The highest rainfall in certain regions of Argentina and Brazil tend to disturb the crops and cause deadly mudslides.
In the specific case of Paraguay, El Niño is characterized by rainfall of varying magnitude and intensity and at the same time the temperature has a tendency to be higher due to the prevalence of moisture in the atmosphere.
There is no useful estimates after March 2010. The chances of that date after an episode of El Niño or La Niña or near-neutral conditions are simply a matter of climatological statistics.
Finally, El Niño also has a positive side, for example, due to the presence of this hurricane season to begin in the equatorial Atlantic Ocean and move to the Caribbean and North America will be weaker. In the same vein, try to charities winter rainfall in the arid Southwest United States and reduces the risk of fires in Florida.
