El Nino and La Nina
El Niño & La Niña
It should be recognized that the strong weather pattern called El-Nino-Southern Oscillation, or ENSO, is unfortunately an unavoidable occurrence. This weather formation is known as an essential process for maintaining long-term global climate stability throughout the year. El Nino and La Nina, two phenomenal and impacting events, generally occur in the ocean surface temperature across the central and eastern tropical Pacific. However these two weather extremes are two entirely different conditions, transpiring in distinctive parts of the world, impacting dangerously in certain areas and differentiating in frequency.
The term El Nino, simply translated into “little boy,” is normally characterized by an abnormally warm sea surface temperature that appears along the west coast of South America. In contrast, one can perceive La Nina as the “little sister” and certainly the total polar opposite of El Nino. Also identified as the Pacific cold episode, La Nina can be described as unusually cool water in the central and east central equatorial Pacific. According to environmental studies, as the result of warmer waters, there appears to be suppression in normal upwellings of cold, nutrient-rich filled water. However, the only other condition that could bring back the upwellings in the ocean would be the La Nina.
The warmer phase of El Nino has been known to effect winter seasonal atmospheric movement across the eastern North Pacific and North America. While in contrary, the colder phase of La Niña tends to impact wintertime atmospheric flow across the eastern North Pacific and North America. Both events have influenced the development of hurricanes, such as El Nino in more eastern Pacific hurricanes and fewer Atlantic hurricanes, whereas in vice versa, La Nina in fewer eastern Pacific hurricanes and more Atlantic hurricanes.
One of the imperative dissimilarities between La Nina and El Nino is in association with the frequency of their incidence. It

    Hurricanes get their energy from low pressure zones in the tropical latitudes. Cooler waters or a change in wind speed or direction are some factors that weaken hurricanes. Hurricanes grow in strength over warm waters because there is more moisture in the air which helps cloud formation, which in turn strengthen the storms. So with cooler water there would be less moisture in the air which in turn would slow the hurricane down. A change in wind direction or speed would cause a mixing of the drier air into…

    So the simple way of explaining a teleconnection is a warmer and cooler pacific can influence rainfall. “we saw how a vast warming (El Niño) or cooling (La Niña) of the equatorial tropical Pacific can affect the weather in different regions of the world” (Ahrens, 2015, p.271). These major storms as we learned in earlier chapters affect people in many regions of the world. A seasonal forecast is very important because it gives people a chance to prepare for what could possibly be. Forecasters can give a prediction of a wetter or drier season. They have said that this type of forecasting has been seen to be very keen in this field of work. If we can predict weather patterns for the upcoming months will only prevail for regions abroad. This will only prepare us for the worst and hope for the best.…

    • Many of the climate events we have discussed require an understanding of ocean and atmospheric circulation, the notion of feedbacks, forcings (the difference in how much energy is absorbed and how much is released), thresholds, and oceanic and longer-term carbon cycling processes (1000 years to overturn). If these terms make you nervous then you want to look back over the relevant set of note.…

    A decrease in precipitation during the dry season (which can last up to 4 months of the year) is expected. Reduced rainfall and prolonged drought are features of an El Nino year and these will be experiences more frequently. It is possible that more intense rainfall will be experiences during the wet season.…

    During the summer and fall the Bermuda high forms over the Atlantic Ocean. Hurricanes moving toward the west from Africa may increase its intensity as it approaches the United States.

    Hurricanes have always bedevilled coasts, but global warming may be making matters worse. The most important parameter which determines hurricane intensity is sea surface temperature. Warmer water means more availability of warm, moist air thus incensing hurricane intensity. As heat from the ocean fuels the storm, an increasingly larger proportion of tropical storms are turning into hurricanes. Sea level is rising and will continue to rise as oceans warm and glaciers melt. Rising sea level means higher storm surges, even from relatively minor storms, which increases coastal flooding and subsequent storm damage along coasts.…

    The ENSO cycle is fluctuations in temperature between the ocean and atmosphere in the Equatorial Pacific off the west coast of South America. La Niña is the cold phase of ENSO and El Niño is the warm phase of ENSO. These changes from normal surface temperatures can have huge implications in the ocean environment as well as on global weather and climate. El Niño and La Niña usually last for several months, but some occurrences have been known to last for a year or more. While the periods of ENSO are very irregular, El Niño and La Niña events occur roughly every two to five years. Usually, El Niño occurs more often than La Niña. Typically, El Niño weather changes occur over North America during the early winter months. It usually creates warmer than average temperatures over the western and northern US states and western Canada. In the Gulf Coast region of the US, it can create wetter than average conditions that can cause flooding, and can actually cause less moisture in the Ohio Valley and the Pacific Northwest regions of the US. On the opposite end of the spectrum, La Niña occurrences cause periods of cooler sea surface temperatures across the Equatorial Pacific off the coast of South America. The effects of La Niña are opposite those of El Niño, and can bring distinctive changes to the affected areas climate. During a La Niña year, winter temperatures are warmer…

    In a warmer world, additional rain at middle and high latitudes, plus melt from glaciers, will add more fresh water to the oceans. This could affect currents, such as the Gulf Stream, that transport heat north from the tropics and might result in parts of North America and Europe becoming relatively cooler. Even if this were to occur, it would take many years or decades because oceans move heat and cold much more slowly than the atmosphere. (Some ocean changes, however, such as the periodic warming of Pacific Ocean waters known as El Niño, may affect regional weather patterns within…
