What is El Niño?

Back

El Niño is a climate pattern characterized by the warming of ocean surface temperatures in the central and eastern tropical Pacific Ocean, which can disrupt normal weather patterns globally.

What is La Niña?

Back

La Niña is a climate pattern characterized by the cooling of ocean surface temperatures in the central and eastern tropical Pacific Ocean, often leading to opposite weather effects compared to El Niño.

What is upwelling?

Back

Upwelling is the process where cold, nutrient-rich water rises to the surface, often enhancing marine productivity and supporting ecosystems.
