Oceanic Oscillations

Oceanic Oscillations

Oceanic oscillations are large-scale climate patterns that involve significant variations in sea surface temperatures and atmospheric pressure across vast ocean basins. These oscillations can have profound impacts on global weather and climate.

• El Niño-Southern Oscillation (ENSO)
  • Involves fluctuations in sea surface temperatures and atmospheric pressure across the Pacific Ocean.
  • Includes two phases: El Niño and La Niña.
  • Significant impacts on global weather patterns, including rainfall, temperature, and wind patterns.
• Pacific Decadal Oscillation (PDO)
  • A long-term climate pattern in the Pacific Ocean, characterized by fluctuations in sea surface temperatures over a timescale of decades.
  • Can influence weather patterns, including rainfall and temperature, over North America and other regions.
• Atlantic Multidecadal Oscillation (AMO)
  • A long-term climate pattern in the Atlantic Ocean, characterized by fluctuations in sea surface temperatures over a timescale of decades.
  • Can influence hurricane activity, precipitation patterns, and other aspects of climate in the Atlantic region.
• Impacts of Oceanic Oscillations
  • Significant impacts on global weather patterns, including rainfall, temperature, and wind patterns.
  • Influence on marine ecosystems, affecting fisheries and other marine life.
  • Socioeconomic impacts on agriculture, fisheries, and human health.
