About a decade ago I showed that this phenomenon amplifies the climate variability everywhere it strikes, including Australia. And how was it discovered? And how does it affect Australia?
This morning, before writing this column, I spent a considerable amount of time watering my wilting garden. Meanwhile, the New York Yankees have been rained out for their third consecutive game.
And out in California? Rain, no rain, rain, no rain Why are we suffering such severe weather this summer? In case you have not heard, we are experiencing a weather phenomenon called El Nino. Without the wind at its back, seawater that typically Term paper el nino up on the jagged western edge of the Pacific -- around Indonesia, the Philippines and Australia -- slides back toward the Americas.
The sliding water moves in what scientists call Kelvin waves. That causes the initial warming," said McPhaden.
At the same time, the Pacific reacts to the lost wind by building another series of waves under water.
Calledthey roll west toward Indonesia, the Philippines and Australia. Eventually, the series of waves strikes the coasts of those countries.
Then, it reverses and heads back toward South America, traveling along the equator. Sometimes an extremely warm event can develop that last for much longer time periods. A strong El Nino developed in and lasted until We are apparently experiencing one of these stronger El Ninos, as this one has lasted for nearly six months.
But how long will this last? However, in some years the trade winds can become extremely strong and an abnormal accumulation of cold water can occur in the central and eastern Pacific. This event is called La Nina.
Two independent computer models that forecast El Nino see on the horizon a pronounced cooling of the same area of the Pacific. Sometimes, the cold water is just enough to return ocean temperatures to normal.
Climate experts agree that the forecasts should be viewed with considerable caution. From now on, we can start blaming the onset of La Nina. Most people will not notice the transition from El Nino to La Nina, as the weather will still be hot and there will initially be increased rainfall, particularly in California, which we may from this point forward refer to as CaliforNina.Environment term papers (paper ) on El Nino: El Nino What Are We Going To Do?
