yup. outdated. but in response to you Boo, I read an article recently, not even sure what it was about now, might of been about the flooding in Australia, but anyways what I read called it La Nina. Possibly the southern hemisphere has a female version of our El Nino.
What is the difference between La Niña and El Niño?
El Niño and La Niña are extreme phases of a naturally occurring climate cycle referred to as El Niño/Southern Oscillation. Both terms refer to large-scale changes in sea-surface temperature across the eastern tropical Pacific. Usually, sea-surface readings off South America's west coast range from the 60s to 70s F, while they exceed 80 degrees F in the "warm pool" located in the central and western Pacific. This warm pool expands to cover the tropics during El Niño, but during La Niña, the easterly trade winds strengthen and cold upwelling along the equator and the West coast of South America intensifies. Sea-surface temperatures along the equator can fall as much as 7 degrees F below normal.
