Transcript of El Nino
It can last 9 months to 2 years. How does this happen ? - trade winds go from East to West and pushes the warm surface water to the west Pacific
- upwelling of cold water in the east Pacific - trade winds are too weak to push the warm water to the west
- warm water spreads all over the Pacific Ocean
- no upwelling What are the effects of El Niño? - South America gets cooler and wetter
- rain clouds move towards the coast of SA and bring heavy rains and floods - upwelling of cold water brings nutrients to the coast of South America, which leads to a large fish population
- during El Niño, the water has less nutrients -> less fish population -> bad for the economy Indonesia, Philippines, Australia and some other countries in the west Pacific are getting hotter and dry. This leads to drought and bushfires. Because of El Niño people may get hurt or killed and damage could be caused (crops, buildings, ... ) In the year 1998 more than 2000 people were killed and billions of dollars were caused by the El Niño.
