The history of El Nino:
1876 was considered the year when spotted similar to the phenomenon of El Nino episode, recorded effects, note that scientists attribute the first recorded incident in history to the middle of the fifteenth century, almost, where the historical sources indicate the year in which the events similar to accompany the El Nino phenomena occurred.
The twentieth century has witnessed the first incident involving Balnino in 1982, which was considered the most when it hit the South American coast, where high temperatures were recorded in the Pacific Ocean and reached 150 degrees Celsius, and in 1992-2002 was of this phenomenon disastrous consequences for farmers and fishermen in many countries of the world.
The World Food Organization, that the El Nino causing higher food prices globally, because of their impact on agricultural products. US National Oceanic and management of the environment has announced that this climatic phenomenon have hurt a lot of poor countries, especially in Africa, and remains one of the El Nino phenomena that baffled scientists, as a phenomenon that can not be predicted in advance.
Most scientists believe today that modern science has yet to find the real and obvious reason for the emergence of this natural phenomenon, and that does not work in the planned rotation in which the repeated El Nino appears, and therefore can not be predicted before they happen to take the necessary measures to reduce the negative effects action mode
Considered El Nino stronger climatic phenomenon exposed to the world and is expected to be for this phenomenon in this year's significant impacts, and lead to an unprecedented rise in temperature, where some of the world saw high temperatures have claimed many lives and caused illnesses and cases of suffocation, while experiencing other parts of the world heavy rains, that El Nino will be the strongest this year.
How El Nino occurs?
Heating: The presence of hot currents in the Pacific Ocean heading towards the east to reach the coast of South America as a result of heating caused by these currents to the Pacific seabed, it is possible to form with other integrated system, lead to a big change in water temperatures and thus the occurrence of El Nino.
Snow: The winter of heavy snow falling on the Asian continent, leading to the creation of a thermal imbalance in the snow melts in the summer, and thus imbalance in traffic near the Pacific Ocean water currents.
Other factors such as the effect of some nearby planets or solar storms also change in the Earth's rotation.
Meteorological Authority of Australia has shown in its report, that the weather phenomenon El Nino that affect the world may continue until the end of the year 2015, as the body showed that three out of five models to the weather forecast actually complete the formation of El Nino, pointing out that temperatures tropical region of the Pacific Ocean were higher many of El Nino threshold.
Australian Authority for Meteorology and says that as a result of weather conditions that accompany El Nino, the conditions will not be suited for the cultivation of wheat in the country, and that the sugar production may drop in the world, and this means that the El Nino effect as a phenomenon of climate on agricultural production, leading to low productivity and high world prices for food. The Board also predicted that the winter will be less cold and less vulnerable to rain because Balnino (quoting meteorological Australian body).
Good luck :)
