[PDF] according to researchers how is a la niña event triggered

They discovered these events are fueled by warming in the western Pacific Ocean and steep gradients in sea surface temperature from the western to central Pacific. “Warming in the western Pacific triggers the rapid onset and persistence of these events,” said Wang.

  • How is a La Niña event triggered?

    La Niña is caused by a build-up of cooler-than-normal waters in the tropical Pacific, the area of the Pacific Ocean between the Tropic of Cancer and the Tropic of Capricorn. Unusually strong, eastward-moving trade winds and ocean currents bring this cold water to the surface, a process known as upwelling.1 déc. 2022

  • What is the La Niña explained?

    La Nina refers to the periodic cooling of ocean surface temperatures in the central and east-central equatorial Pacific. Typically, La Nina events occur every 3 to 5 years or so, but on occasion can occur over successive years. La Nina represents the cool phase of the El Nino/Southern Oscillation (ENSO) cycle.

  • What is a La Niña event quizlet?

    slide 2 -What is La Niña. A climate pattern that describes cooling of surface ocean waters along tropical west coast of south America. -Typically follows El Niño. -occurs about every 2-7 years.
  • In the 1980s, when the opposite phase of El Niño was discovered (i.e., cooler-than-normal ocean temperatures), scientists called it “La Niña” (Spanish for little girl).18 jan. 2016
