    • 2011 La Niña Weather Phenomenon
      By Ryan
    • What Happened?
      • Recently there has been drastic weather changes around the world.
      • This has been blamed all on the La Niña weather phenomenon.
      La Niña weather phenomenon events from1950 to 2011
    • What is La Niña
      La Niña is a combined ocean-atmosphere phenomenon that is the counterpart of El Niño as part of the broader El Niño-Southern Oscillation climate pattern. During a period of La Niña, the sea surface temperature across the equatorial Eastern Central Pacific Ocean will be lower than normal by 3–5 °C. In the United States, an episode of La Niña is defined as a period of at least 5 months of La Niña (drastic and unusual) weather conditions.
    • Effects
