Study Notes
El Niño and La Niña
- Weakening of the usual trade winds in the tropical Pacific leads to El Niño.
- Cancellation of the normal temperature difference in the tropical Pacific occurs when the trade winds weaken, allowing warmer water to flow back towards the east.
El Niño Impacts
- Around the tropics, El Niño can lead to droughts in some regions and heavy rainfall in others.
- El Niño causes a rise in global temperatures, making it a warming phenomenon.
La Niña
- During La Niña, the trade winds strengthen, and the cold water is pushed towards the surface, making the eastern Pacific even cooler.
Cause of El Niño
- The main cause of El Niño is the weakening of the trade winds, which allows the warmer water to flow back towards the east.
Ocean Currents
- The Pacific Ocean experiences consistent trade winds that push warm water from east to west.
- The trade winds cause the warmer water to pile up on the western side of the Pacific Ocean.
Temperature Difference Impacts
- The temperature difference across the tropical Pacific has a significant impact on air and weather patterns, influencing global climate conditions.
