El NinoThis morning, before make-up this essay, I spent a considerableamount of time tearing my wilting garden. Meanwhile, the New YorkYankees fuck off been rained issue for their third consecutive game. And outin California? Rain, no rain, rain, no rain... Why are we execrablesuch severe stomach this summer?

At the same time, thePacific reacts to the lo st wind by building another series of wavesunder water. Called , they roll west toward Indonesia, the Philippinesand Australia. Eventually, the series of waves strikes the coasts ofthose countries. Then, it reverses and heads back toward South America,traveling along the equator.

Sometimes, the coldwater is just enough to return ocean temperatures to normal. Notalways. Sometimes, it overshoots, McPhaden said. That would bring aLa Nina after El Nino.The models say . . . there will be a cold effect sometime next year --
