The correct answer is La Nina

Key Points

  • La Nina is the cold phase of the ENSO (El Niño-Southern Oscillation) climate pattern.
  • It describes the unusual cooling of the surface waters in the central and eastern tropical Pacific Ocean.
  • La Nina events typically bring about a variety of weather changes, including increased rainfall in some regions and drought in others.
  • This phenomenon is the opposite of El Niño, which is the warm phase of the ENSO climate pattern.
  • La Nina can influence global weather patterns and has significant impacts on agriculture, water supply, and hurricane activity.

Additional Information

  • The ENSO cycle includes both El Niño and La Nina phases, as well as periods of neutral conditions.
  • La Nina events are characterized by stronger-than-average trade winds, which push warm water towards the western Pacific, allowing cold water to upwell in the eastern Pacific.
  • The cooling effect of La Nina can last for several months and typically occurs every 2 to 7 years.
  • La Nina can also influence the Atlantic hurricane season, often leading to more active hurricane periods.
  • Scientists monitor the ENSO cycle using various tools, including satellite observations and ocean buoys, to predict and understand its impacts.
