8. 1.What is El Nino? 2. How often does El Nino happen? 3. What unusual happens to the water of the Pacific Ocean, West of South America during El Nino? 4. How is South America and Australia affected by El Nino? A chaotic weather phenomenon. Characterized by the warming of the Pacific Ocean. Appears every 3-7 years, and tends to happen around December. Unusual warming of ocean water. No one knows how. South America has more rainfall and Australia experiences drought.

9. 5. What is La Nina? 6. How do the oceans affect the weather? It is the cooling of the Pacific Ocean. Causes flooding in Australia. The unusual heating and cooling of the ocean creates and imbalance that alters the global wind patterns.

10. 7. What are the effects of El Nino and La Nina? El Nino results to weaker Trade Winds and warmer Pacific Ocean. Flooding in South America, drought in Southeast Asia and Australia. Ice storms, drought, and mudslides in North America. La Nina results to stronger Trade Winds and cooler Pacific Ocean. Weather is opposite to El Nino.

11. Trade Winds are winds near the equator. Equator Trade Winds ( northeast) Trade Winds (southeast) Trade Winds are weaken during El Nino. Trade Winds are stronger during La Nina.

12. 8. How is the United States affected by El Nino? Drought Very Cold Severe Storms Storms, precipitation

14. Weak (WE), Moderate (ME), and Strong El Niño (SE).

17. Ocean water temperatures have a great effect on weather patterns, including creating hurricanes and providing energy for coastal storms.

18. Hundreds of years ago, South American fishermen observed that every year around December or Christmas, coastal waters of the Pacific became warmer as a current flowed from north to south. This change often meant a smaller catch but more rainfall inland. And that translated to more abundant crops. They called it El Niño.

19. El Niños can bring heavy rainfall and flooding to the West Coast of South America. Meanwhile, Australia and Southeast Asia may face a drought and high risk of wildfires. In North America, scientists have also linked unusual weather events — including ice storms, droughts and mudslides — to the arrival of an El Niño.
