Best answer: How do El Nino and La Nina affect climate quizlet?

How do El Nino and La Nina affect climate?

El Niño impacts weather systems around the globe, triggering predictable disruptions in temperature, rainfall and winds. La Niña is the opposite – a cooling phase of ENSO that tends to have global climate impacts opposite to those of El Niño.

How do El Nino and La Niña affect climate quizlet?

What are the weather conditions during El Niño? Sea surface temperatures are warmer, which increases evaporation which causes an increase in precipitation. … Ocean water near the equator shifts between warmer than average (el Nino) and colder than average (la Niña) conditions.

How does El Nino affect climate?

What is El Niño? By changing the distribution of heat and wind across the Pacific, El Niño alters rainfall patterns for months to seasons. As the warm ocean surface warms the atmosphere above it, moisture-rich air rises and develops into rain clouds.
