However, during an El Nino year, upwelling is contain and as a result, the thermocline is lower than normal. Finally, thermocline rises in the west, making upwelling easier and water colder.

Air hugs at sea level in the South Pacific play back and forth between two unambiguous patterns. In the high index phase, also called Southern Oscillation, pressure is higher near and to the east of Tahiti than farther ! to the west near Darwin. The east-west pressure end on the equator causes the surface air to flow westward. When the aureole switches into the low index phase, barometers rise in the west and pass along in the east, signaling a...
