● El Niño and La Niña are opposite phases of a natural climate pattern in the Pacific Ocean called the El Niño-Southern Oscillation (ENSO). ● They have far-reaching effects on weather patterns worldwide.
○ Increased rain over the Americas in the Eastern Pacific central and eastern equatorial Pacific Ocean are warmer than average. ● This disrupts normal wind and rainfall patterns. ● Typical Effects Include: ○ Increased rain over the Americas in the Eastern Pacific ○ Drier conditions in Southeast Asia and Australia ○ This can lead to more hurricanes in the Eastern Pacific
● La Niña involves cooler-than-average sea surface temperatures in the same Pacific region. ● It often intensifies normal wind and weather patterns. ● Typical Effects Include: ○ Drier conditions in the America ○ Wetter conditions in Southeast Asia and Australia ○ This can lead to more hurricanes in the Atlantic Ocean
● Both are natural climate patterns, not caused by human activity. ● Both can last for several months to a couple of years. ● Both affect weather patterns across the globe. The ever-present blue vastness of the North Atlantic Ocean frames the vivid yellow and black. ● The contrast between the three colors is genuinely awe-inspiring.
