A 3D Look at the 2015 El Niño

The video explains El Nino, a climate phenomenon characterized by warmer than normal temperatures in the Equatorial Pacific Ocean. It highlights the 2015 El Nino event, which peaked in December and returned to normal by April 2016. The video describes how changing winds push warm waters from Indonesia to the Americas, affecting ocean currents. NASA uses this data to enhance forecasts of future El Nino events and their global impacts.

What is El Nino primarily associated with?

• Higher atmospheric pressure

• Warmer than normal Equatorial Pacific Ocean temperatures

• Increased volcanic activity

• Decreased solar activity

During which months did the 2015 El Nino peak and return to normal?

• October and February

• December and April

• November and March

• January and May

What role do changing winds play in an El Nino event?

• They increase atmospheric pressure

• They drive warm waters from Indonesia to the Americas

• They cause volcanic eruptions

• They cool the ocean surface

What do the yellow arrows represent during an El Nino?

• Eastward currents

• Westward currents

• Southward currents

• Northward currents

How has NASA used data from El Nino events?

• To measure atmospheric pressure changes

• To predict solar flares

• To improve forecasts of future El Nino events and their impacts

• To track volcanic activity
