- Winds that weaken during El Nino, resulting in an increase in ocean surface temperatures
- Winds that strengthen during La Nina, causing less warm water to remain
What is the significance of El Nino?
What is the significance of El Nino?
- It strengthens trade winds, causing less warm water to remain
- It causes wetter areas to experience decreased flooding
- It results in an increase in ocean surface temperatures affecting rainfall, atmospheric winds, and the polar jet stream (correct)
- It leads to strengthening of upwelling, bringing more nutrient-rich, cold water from the depths
