    The term El Niño Southern Oscillation (ENSO) basically refers to both the El Niño and La Niña phenomena together. See this page for a more detailed explanation of what happens in the ocean and atmosphere during ENSO. A very strong El Niño in – large 'red tongue' in equatorial Pacific.   El Niño and La Niña are the warm and cool phases (respectively) of a recurring climate phenomenon across the tropical Pacific - the El Niño-Southern Oscillation, or 'ENSO' for short.

      Lizarraga: Yes, El Niño is a recurring phenomenon. Peru should be on a par with Japan in terms of how the latter prepares for any seismic activity. We still have enough time to . During El Niño, which was in occurring in early , the easterly trade winds are weaker than usual, and the South Pacific Convergence Zone slides northeast of where it is during other phases of the El Niño-Southern Oscillation. The location of the 10 tropical cyclones in the basin during the season was consistent with that pattern.

The El Niño-Southern Oscillation Phenomenon. Edward S. Sarachik, Mark A. Cane; Online ISBN: El Niño usually lasts one or two years. It is followed by the opposite phenomenon called La Niña. During La Niña, particularly strong trade winds push the warm surface waters back toward the western Pacific, which causes very strong monsoon rains in Asia and sometimes landslides as well.

An introduction to all aspects of the important and topical El Niño/Southern Oscillation (ENSO) phenomenon. This El Niño phenomenon. book grounds ENSO in an observational and theoretical context, and describes its impacts and methods for prediction.

An essential introduction to ENSO for graduate students and researchers in atmospheric science and oceanography.5/5(5). Semiannual and annual oscillations of sea level and their impact on asymmetry between El Niño and La Niña episodes. Studia Geophysica et Geodaetica, Vol.

58, Issue. 2, p. Chapters on ENSO prediction, past and future, and impacts, introduce broader implications of the phenomenon.

This book provides an introduction to all aspects of Cited by:   El Niño was recognized by fishers off the coast of Peru as the appearance of unusually warm water. We have no real record of what indigenous Peruvians called the phenomenon, but Spanish immigrants called it El Niño, meaning “the little boy” in Spanish.

This book examines the role of the El Niño Southern Oscillation (ENSO) in society. Throughout human history, large or recurrent El Niños could cause significant disruption to societies and in some cases even contribute to political change.

Yet it is only now that we are coming to appreciate the significance of the phenomenon. El Niño is a climate phenomenon that occurs when a vast pool of water in the eastern tropical Pacific Ocean becomes abnormally warm. Under normal conditions, the warm water and the rains it.

Meteorologists now recognize a phenomenon related to El Niño called La Niña, in which conditions are nearly opposite those of El Niño. The diagrams and text below compare the features of the ocean and atmosphere that accompany normal, El Niño, and La Niña conditions.

Analyzing the long-term behavior of the coastlines in the vicinity of river mouths and estuaries usually relies on the mean (predicted) values of the sediment discharge from the river.

However, this approach does not consider low frequency, severe events, such as El Niño (EN), that can have a large effect on coastlines. While the effects of an EN on flooding and droughts are well studied.

El Nino and the Southern Oscillation is by far the most striking phenomenon caused by the interplay of ocean and atmosphere. It can be explained neither in strictly oceanographic nor strictly meteorological terms.

This volume provides a brief history of the subject, summarizes the oceanographic and meteorological observations and theories, and discusses the recent advances in computer modeling. La Niña (/ l ɑː ˈ n iː n j ə /, Spanish pronunciation:) is a coupled ocean-atmosphere phenomenon that is the colder counterpart of El Niño, as part of the broader El Niño–Southern Oscillation climate name La Niña originates from Spanish, meaning "the little girl", analogous to El Niño meaning "the little boy".It has also in the past been called anti-El Niño, and El.

El Nino: Unlocking the Secrets of the Master Weather-Maker by J. Madeline Nash is a climate-science based book full of information about El Nino and anecdotes of the real scientists who studied it. The book describes the many ways that the phenomenon of El Nino affects people and places all around the s: 9.

El Nino is a weather pattern which usually peaks during the winter months of the northern hemisphere. This weather pattern involves interaction between the ocean and the atmosphere, resulting in warmer waters in major areas of the Pacific Ocean.

When that happens, global weather patterns will be affected. The El Niño phenomenon is the Earth’s strongest climatic fluctuation on an interannual timescale and has a quasi-global impact, although originating in the tropical Pacific Ocean.

1. Introduction. The El Niño and La Niña events can have major implications for food production worldwide, with varying levels of impacts depending on the geographical region (Lizumi et al., ; Wu et al.,; Naylor et al., ; Phillips and McIntyre, ; Meza et al., ; Bannayan et al., ).Lizumi et al.

() provided a global assessment and concluded that El Niño. Sea surface temperatures usually peak around December (The phenomenon was called El Niño, Christ Child in Spanish, because of the time of year it generally occurs.), but bigger impacts are often felt a few months later as global oceans gradually heat up.

This year’s El Niño will likely last through March and could persist until May. Note that the ECCO product used hereafter covers seven El Niño events (with the four more El Niño events than Argo, including –, –, –, and – than Argo) and six La Niña events (including the three more than Argo including –, –, and –).

Though ENSO is a single climate phenomenon, it has three states, or phases, it can be in. The two opposite phases, “El Niño” and “La Niña,” require certain changes in both the ocean and the atmosphere because ENSO is a coupled climate phenomenon.

“Neutral” is in the middle of the continuum. Fishermen in South America, who have long known and described the phenomenon, called it “El Niño” because the some of the biggest effects spin. El Nino's Relationship to Climate Change.

As of this writing, El Nino and La Nina do not appear to be significantly related to climate change. As mentioned above, El Nino is a pattern that had been noticed for hundreds of years by South Americans.

Climate change may make the effects of El Nino and La Nina stronger or more widespread, however. Can We Blame El Niño for These Events.

People have noticed that when the Pacific Ocean is unusually warm near the beginning of the year, certain things are more likely to happen. These events are linked to a Pacific Ocean phenomenon known as the El Niño Southern Oscillation (ENSO).

NOAA: Extreme Weather: US Army Corps of Engineers Coastal. "El Niño de Hollywood" pareciera ser solo un libro que habla sobre Miguel Ángel Tobal "El Niño" y la inverosímil historia de su vida. Sin embargo como lo dice el mismo libro, cuenta la micro - historia de un cantón del municipio de Atiquizaya en El Salvador, y a la vez va hilvanado hilos de fenómenos nacionales y globales que inciden en Reviews:.

The complex El Nino phenomenon will potentially bring a droughts and monsoons led to millions of deaths under hellish conditions," wrote historian Cormac O Grada in his book.

El Niño and the Southern Oscillation (ENSO) can't be completely understood without understanding both atmospheric and equatorial ocean dynamics. The book requires that the reader is familiar with basic fluid mechanics on a rotating earth. s: 6.El Niño is a phenomenon that occurs when unusually warm ocean water piles up along the equatorial west coast of South America.

When this phenomenon develops, it affects weather patterns around the globe, including the winter weather along the west coast of North America.

This unusual pattern of sea surface temperatures occurs in irregular.
