The weather and climate condition known as El Nino is caused by changes in wind Warmer waters are pushed westward along the equator and they form a While their frequency can be quite irregular, El Nino and La Nina events occur on average every two to seven years. Typically, El Nino occurs more frequently The weather phenomenon known as El Nino is caused by weakened trade winds over the Pacific Ocean. Normally, warm water is pushed to the western Pacific The formation of El Nino is linked with the cycling of a Pacific Ocean circulation pattern known as the El Nino Southern Oscillation or ENSO. In a normal year, low atmospheric pressure develops over northern Australia and Indonesia, with high pressure over the Pacific. The thermocline is deeper, and sea level higher, in the western Pacific than in the east. During El Nino, warm surface water appears farther east and is spread over a broader area. Weak Highs form east and west of the Low, and surface and upper level winds are both weaker than normal. Combined, these form an operational El Nino/Southern Oscillation (ENSO) observing system. See the 30 Oct 2015 El Nino events occur irregularly at two- to seven-year intervals. This thick layer of warm water does not allow normal upwelling to occur. El Nino is an unusual warming of the tropical Pacific Ocean that occurs irregularly at about 3-6 year intervals . So, did El Nino also occur during the ice ages? 20 Aug 2015 El Nino is a Pacific Ocean climate cycle with a global impact on weather patterns. How often do El Ninos occur? El Ninos occur every three to 25 Jun 1997 Description of El Nino from the Climate Research Division of the Scripps Institution of At the same time, the place where hefty thunderstorms occur on the equator moves eastward.
