El-Nino Affect Weather Worldwide

Government scientists on Thursday, the periodic warming of water in the tropical Pacific, at the time in the world, is back.

The Pacific has been in what is regarded as neutral, but forecasters at the National Oceanic and Atmospheric Administration said that the water temperature has risen by 1.8 degrees Celsius above normal over a narrow band in eastern equatorial Pacific, in June.

In addition, NOAA's Climate Prediction Center said tropical temperatures in other regions are also above normal, with readings warmer than usual, as far as 975 meters below the sea surface.

In general, El Nino conditions associated with increased rainfall in the east central and eastern Pacific and dry as normal conditions over northern Australia, Indonesia and the Philippines.

One summer, El Nino can lead to normal weather in the Intermountain regions of the United States and central Chile. In an El Nino years is rather Pacific hurricanes and fewer Atlantic hurricanes.

The meteorologists said expect that this El Nino continues to improve in the coming months and last winter over the years 2009-2010.



"Advanced Life Sciences climate allows us to warn of industry, governments and operators urgently to the climatic conditions of El Nino May, so that they can be taken into account in making decisions and, ultimately, the protection of lives, property and the economy", Board member Jane Lubchenco of NOAA said in a statement.

NOAA pointed out that the effects of El Nino are negative. For example, the Atlantic hurricanes and humidity for the dry regions of the southwest.

It can also be damaged drivers in winter storms in California and the increase in storms in the southern United States.


The warming of the sea can also contribute to a reduction in catches at sea on the west coast, and fewer fish can also affect food source for birds and marine mammals.

A study by researchers from Georgia Tech in May showing there are actually two types of El Nino, according to whether the warming is strongest in the eastern part of central or rest.

Although the current warming seems to be strong in the east of the form of a traditional, government forecasters were unable to them.

If the Georgia Tech study is correct, it is nature, that the phenomenon El NiƱo storms in the Atlantic and Caribbean. The form of the other, further west, appears to be at the Atlantic storms.
