What is the origin of the name El Niño?

• It refers to a strong hurricane in the Atlantic Ocean.

• It was named by Peruvian fishermen due to its effects on their catch.

• It means "the big storm" in Spanish.

• It describes a cooling of ocean waters near South America.

How does El Niño affect the movement of warm waters in the Pacific Ocean?

• It strengthens winds that push warm waters toward Indonesia and Australia.

• It cools the waters in the eastern Pacific Ocean.

• It causes winds to slow down, allowing warm waters to spread eastward.

• It redirects warm waters toward the Atlantic Ocean.

How can El Niño impact the geologic landscape?

• It causes sea levels to drop, exposing more land, light winds, and moderate rainfall
  

• It leads to increased volcanic activity worldwide, both for active and inactive volcanoes.

• It can cause increased rainfall and flooding, drought conditions, and possible sea level rise.
  

• It only affects the atmosphere and has no impact on the landscape.

How have El Niño predictive models improved over time?

• They now provide forecasts up to 18 months in advance using past climate data.

• They rely on real-time ocean temperature readings for predictions.
  

• They have become less accurate due to unpredictable climate changes.

• They can predict El Niño 1 – 2 months before they occur through robotic mechanisms
