El Nino 2014
At irregular intervals from 2 to 5 years two weather phenomena of El Nino and La Nina turns the Pacific Ocean. Both exceptional weather events have strong significance for the crop results for large parts of the agriculture in the adjacent areas.
For the second half of 2014 climatologists expect variant of the El Nino a 70% probability for the occurrence. In this case, the cold Humboldt current on the South American West Coast breaks down. Collapses the trade flow from East to West. The rain clouds no longer reach the Southeast Asia (Australia, Malaysia, Indonesia) but before rain down or return even with the Northern flow in the northern part of the South American coast. Catastrophic floods in the towering Andes to Peru can be the result. The name comes from this region.
The changed flow situation draws more circles. Missing in Southeast Asia reached the South China area rainfall and drought can take on larger proportions. In North America, Alaska and Canada to the West and east coasts with warmer temperatures than usual benefits. The southern part of the United States gets more precipitation.
In South America it occurs in northeast of Brazil the drought while increasing the runoff in Argentina. for other areas, no typical effects can be detected cause.
The respective amount of the unusual weather changes is different in each campaign. The in this regard established weather stations show the characteristic changes of water temperatures over several months in early and late summer to autumn, reveal only the direction, but not the intensity. The full effects occur usually until the turn of the year and disappear again in the spring.
The climate change but enough to noticeably affect the harvest results in agriculture. In the United States, the southern States benefit from higher rainfall. These include the extensive pasture areas and North part of the corn and soybean area. In Argentina, higher rainfall normally are desirable, but also not too hard, they may fail. Drought in northeastern of Brazil is for its extensive farming of less importance.
In Australia, particularly the South-East is affected. Crop yields fall regularly significantly. In Malaysia and Indonesia, the dominant palm oil harvest falls back. Drought in southern China concerns especially the rice harvests.
For 2014, the Australian Government based on previous history has responded only with a reduction in the crop estimate. Malaysia and Indonesia a similar clarity does not exist yet. No valid conclusions are drawn in the other regions.
