Document Summary
The sun has a very diferent impact on diferent areas in the world, because the axis is ilted 23. 5 degrees. Muiny on the bounty, the ship stayed in one place for ages because the current was too strong. It is a largescale change in climate paterns. In normal condiions, wind blows from the east to the west. The air movement blow the warm water to the west; oten in asia, you have water that"s relaively warm. The nutrient rich water near the peruvian coast atracts ish. Two loops of wind, of which one goes against the normal condiions. The irst thing that happens is that when the coninuous patern stops, the water washes back up on the peruvian coast; the thermocline doesn"t follow, so no more nutrient rich water comes back up. The warm water actually spreads onto the peruvian coast, and so all the ish leave because the water is too warm for them.
