You might find some el nino adn la nina stuff on http://www.cliffnotes.com. I found quite a few thing on that website

What causes La Niña?*
Typically, a La Niña is preceded by a buildup of cooler-than-normal subsurface waters in the tropical Pacific. Eastward-moving atmospheric and oceanic waves help bring the cold water to the surface through a complex series of events still being studied. In time, the easterly trade winds strengthen, cold upwelling off Peru and Ecuador intensifies, and sea-surface temperatures (SSTs) drop below normal. During the 1988- 89 La Niña, SSTs fell to as much as 4 degrees C (7 degrees F) below normal. Both La Niña and El Niñq tend to peak during the Northern Hemisphere winter. http://www.elnino.noaa.gov/lanina_new_faq.html
hopefully helps a little.

For the southern occilation, I know that the pressure changes (on Darwin + Tahiti islands)?

Does anyone know on which island the pressure increases + on which island the pressure decreases?

Thnx.

and 18 days later, your question is answered.

ok...im a really bad graph reader, but...i think its darwin increases, tahiti decreases...i think

Well I know that during El Nino pressure over Tahiti decreases.

yay!!! then my not so amazing graph reading skills havent failed me yet. So Tahiti decreases, whereas Darwin increases

Yup. That was on my note sheet's el nino/ la nina table lol

Congrats, pgj for meteo.

How was the national test??

Very off topic...Olypionia?
