El Niño and La Niña Flashcards
(26 cards)
El Niño and La Niña are opposite phases of what is known as the [blank] cycle. ————
El Niño-Southern Oscillation (ENSO)
The [blank] is a scientific term that describes the fluctuations in temperature between the ocean and atmosphere in the East-Central Equatorial Pacific (approximately between the International Date Line and 120 degrees west). ————
ENSO cycle
Between El Niño and La Niña, what is sometimes referred to as the cold phase of the ENSO cycle? ————
La Ninya
Between El Niño and La Niña, what is sometimes referred to as the warm phase of the ENSO cycle? ————
El Ninyo
What is a natural climate phenomenon where the surface water in the central and eastern Pacific Ocean becomes unusually warm, causing major shifts in weather patterns worldwide? ————
El Ninyo
What is the meaning of El Niño? ————
The Little Boy or Christ Child in Spanish
El Niño occurs every 2 to ? years and lasts for several months to over a year. ———–
7
What are the causes of El Niño? ————
Weakening or reversal of trade winds–which usually push warm water toward Asia, changes in air pressure (called the Southern Oscillation), disrupt the normal upwelling of cold–nutrient-rich water
Warmer than average waters in the Eastern equatorial Pacific, affects weather around the world. ————
El Ninyo
Among the 8 global impacts of El Niño, give four. ————
Drought, water scarcity, forest fires, floods, overheating, typhoons, agricultural loss, marine life disruption
Warmer water in the Pacific ————
El Niño
Cooler water in the Pacific ————
La Niña
These changes in sea temperature can cause [blank], [blank], and [blank] in many parts of the world. ————
floods, droughts, stronger storms
[blank] is a natural climate event where sea surface temperatures in the central and eastern Pacific Ocean become cooler than normal, causing changes in global weather patterns. ————
La Ninya
If El Niño means Little Boy, what does La Niña mean? ————
The Little Girl
What are the names La Niña is sometimes called? ————
El Viejo, anti-El Ninyo, a cold event
[blank] episodes represent periods of below-average sea surface temperatures across the east-central Equatorial Pacific. ————
La Ninya
Name the three major causes of La Niña. ————
Stronger trade winds, warm water moves, cool water rises
Global impacts of La Niña include flooding in countries like [blank], [blank], and [blank]. ————
Indonesia, India, Eastern U.S
Global impacts of La Niña include heavy rainfall in [blank], [blank], and [blank]. ————
Southeast Asia, Australia, parts of the United States
Global impacts of La Niña include cooler-than-normal temperatures in places like the [blank] and [blank]. ————
Northern United States, Canada
Global impacts of La Niña include a stronger Atlantic hurricane season, with more [blank] and [blank]. ————
storms, hurricanes
Global impacts of La Niña include disrupted agriculture, leading to crop damage from excessive rainfall. ————
True
The ocean temperature of El Niño and La Niña, which between the two, defines warmer Pacific waters and floods in Asia? ————
El Ninyo defines warmer Pacific waters and La Ninya defines floods in Asia
