Question 1

True or false: La Niña occurs when sea surface temperatures in the Pacific rise above average.

Accepted Answer

False. That describes El Niño. La Niña is defined by cooler-than-average sea surface temperatures in the central and eastern tropical Pacific Ocean.

Question 2

True or false: La Niña is the Spanish phrase for 'the little girl' and is part of the ENSO cycle.

Accepted Answer

True. La Niña means 'the little girl' in Spanish, contrasting with El Niño ('the little boy'). It is the cool phase of the El Niño-Southern Oscillation (ENSO) cycle.

Question 3

True or false: La Niña events are linked to a higher risk of Atlantic hurricanes.

Accepted Answer

True. La Niña reduces vertical wind shear in the tropical Atlantic, creating favorable conditions for hurricane formation and intensification, as shown by numerous studies.

Question 4

True or false: La Niña always causes severe droughts in California.

Accepted Answer

False. While La Niña often brings drier conditions to Southern California, it does not always cause severe droughts. Effects vary by event and region. In some years, California has normal rainfall during La Niña.

Question 5

True or false: La Niña was first identified by scientists in the year 2000.

Accepted Answer

False. La Niña was recognized as a climate pattern decades earlier. The term gained popularity in the 1980s, and the phenomenon was observed by Peruvian fishermen in the 1800s.

Question 6

True or false: La Niña typically reduces wind shear in the Atlantic, leading to more hurricanes.

Accepted Answer

True. La Niña's cooler Pacific waters alter atmospheric circulation, decreasing wind shear over the Atlantic. This allows hurricanes to form more easily, a well-documented effect.

Question 7

True or false: La Niña is a localized weather event that only affects the Pacific coast of South America.

Accepted Answer

False. La Niña is a large-scale climate pattern affecting global weather, not just a local event. Its impacts include changes in rainfall, temperature, and storms across the world.

Question 8

True or false: La Niña can bring wetter-than-average conditions to Australia and Indonesia.

Accepted Answer

True. During La Niña, warmer ocean waters near Indonesia enhance convection, leading to increased rainfall in Australia and Indonesia. This is a consistent pattern observed in climate records.
