What Are El Ni\u00f1o and La Ni\u00f1a<\/h2>\n\n\n\n

El Ni\u00f1o and La Ni\u00f1a are both effects of the El Ni\u00f1o Southern Oscillation (ENSO) cycle. About every 3-5 years, the surface temperatures in the Pacific equatorial region fluctuate to the point where the temperatures are either above the average (El Ni\u00f1o) or below the average (La Ni\u00f1a). A long time ago, fishermen in South America noticed the warmer Pacific water temperatures that peaked around December. They named it El Ni\u00f1o de Navidad which was shortened to just El Ni\u00f1o (the little boy) later. La Ni\u00f1a (the little girl) is just the opposite and is marked by a period of colder waters in the Pacific equatorial region.<\/p>\n\n\n\n

El Ni\u00f1o weakens the trade winds which pushes the warmer waters to the east causing the warming of the Pacific waters which in turn causes the jet stream in the Pacific to move south of its normal position. This movement causes the northern US and Canada to experience warmer and drier weather than normal. It also causes the southern US to experience warmer and wetter weather than normal.<\/p>\n\n\n\n

La Ni\u00f1a strengthens the trade winds pushing the warmer waters to the west. This pushing of the waters to the west causes the colder water to be drawn up from deeper in the Pacific causing a cooling of the eastern Pacific. This cooling pushes the jet stream to the north causing wetter weather in the northern US and Canada and warmer, drier weather in the southern US. Sometimes the La Ni\u00f1a conditions will even cause widespread drought in the southern US. La Ni\u00f1a also causes ideal conditions for the formation of tropical cyclones.<\/p>\n\n\n\n

El Ni\u00f1o to La Ni\u00f1a Transition<\/h2>\n\n\n\n

The transition from El Ni\u00f1o to La Ni\u00f1a usually predicts a busier hurricane season than normal. As the gap between the end of El Ni\u00f1o and the beginning of La Ni\u00f1a shrinks, the intensity of that season is predicted to increase. The 2024 season was one of those events.<\/p>\n\n\n\n
