El Nino and La Nina are two periodic changes in ocean circulation patterns. which of these statements best describes their effect on global climate?

El Nino carries warm water, increasing rainfall along the coast of Chile, while La Nina brings cold water upwellings to western South America.

El Nino and La Nina tend to peak during winter months, so by the summer months the climate patterns return to normal conditions.

El Nino and La Nina are recent disturbances in ocean currents oscillating between warm and cold conditions caused by the greenhouse effect.

El Nino and La Nina exclusively affect the climate of the southern Pacific Ocean including South America, Australia and Indonesia.

During an El Niño, it rains

in the central and eastern Pacific.

The change in normal patterns over the Pacific that start the El Niño event involve

weakened trade winds push less warm surface water to the West.

stronger than normal trade winds from East to West.

strengthened trade winds push more cold water Westward.

volcanic activity under water cause changes in the flow of cold water on the coast of South America.

During an El Nino, the shift in trade winds cause sea levels to

Decrease near Australia and increase near Peru.

Decrease near both Australia and Peru.

Increase near both Australia and Peru.

Increase near Australia and decrease near Peru.

Where does the term El Niño come from and what does it mean?

“The Child,” due to its appearance around the Christmas season

"The Chile," due to its appearance around Thanksgiving

"The Kid", due to its appearance around Easter

"The Family", due to its appearance around 4th of July

What oceanic and atmospheric conditions DOES NOT occur during a La Niña?

cold oceanic patterns that occur near the Equator

changes in the intensity and distribution of rainfall in the Tropics

changes in the patterns of sea level pressure

atmospheric circulation that affect many areas worldwide.

How often to El Niño events occur and how long do they generally last?

Occur every 3-5 years/ Usually last for 9-12 months.

Occur every 3-5 weeks/ Usually last for 9-12 days.

Occur every 9-12 years/ Usually last for 3-5 months.

Occur every hour/ Usually last for 15 min.
