El Niño Mini Quiz
Test your knowledge with these top questions!
Pacific trade winds trigger an El Niño event when they do what?
Normally, these winds blow east to west, pushing warm water toward Asia. When they fail, that sun-warmed water flows back toward the Americas.
Peruvian fishermen originally used the Spanish name El Niño to reference what figure?
Fishermen noticed the unusually warm waters arriving around December, so they named the phenomenon after the baby Jesus in honor of the Christmas season.
Climate phenomenon El Niño typically does what to the Atlantic hurricane season?
The phenomenon produces strong vertical wind shear in the Atlantic, which tears apart developing hurricanes before they can fully form.
The El Niño climate cycle alters the Pacific Ocean by doing what to its surface waters?
This unusual warming is concentrated in the central and eastern equatorial Pacific, which blocks nutrient-rich upwelling and disrupts global weather patterns.
The weather pattern El Niño gets its name, Spanish for 'the boy', because it peaks around which holiday?
South American fishermen named the warm current after the Christ Child because the phenomenon typically arrived around late December.
The climate phenomenon El Niño fundamentally alters global weather by doing what to the Pacific Ocean?
This warming occurs when trade winds weaken, allowing warm water from the western Pacific to flow eastward toward the Americas.
Meteorologists track El Niño alongside its direct opposite, a cooling phase known by what Spanish name?
Together, these warm and cool phases form the El Niño-Southern Oscillation, one of the most influential climate cycles on Earth.
The El Niño climate pattern creates wind shear that does what to Atlantic Ocean hurricanes?
Wind shear acts as a stabilizer that prevents storms from developing vertically, effectively tearing the structures of potential hurricanes apart.
