The El Niño Southern Oscillation (ENSO) is an important mode of climatic variability that exerts a discernible impact on ecosystems and society through alterations in climate patterns. For this reason, ENSO has attracted much interest in the climate and health science community, with many analysts investigating ENSO health links through considering the degree of dependency of the incidence of Cited by: 9. The El Niño / Southern Oscillation (ENSO) is Earth's strongest interannual climate fluctuation, impacting weather, ecosystems, and economies around the world. Understanding the range of ENSO variation could help lead to longer range predictions of El Niño and La Niña events. The authors review the current state of understanding of diversity among different El Niño / Southern Oscillation. Note 4: I believe it possible to identify El Ninos events prior to the 16th Century. I have noted some in the relevant pages on this site where I (and others) believe there is a strong likelihood. Those of AD and AD in particular.

The first three sections of this chapter cover the definition of ENSO and the ramifications it has on the planet. A simple introductory explanation of the cause of ENSO was also given. The basis for setting off ENSO events is related to changes in the trade winds leading to a positive feedback.

ENSO by focusing on interaction between the tropical Pacific Ocean and atmosphere [e.g., see ENSO overviews by Philander (), Neelin et al. (), and Wang and Picaut ()]. After TOGA, the ENSO research community focused on different types of ENSO events, ENSO low-frequency variability and ENSO variability under global warming. enso is a creative impact agency.

Historical El Niño and La Niña Events The definition of El Niño(La Niña) is such that the 5-month running mean Sea Surface Temperature (SST) deviation for NINO.3(5°S-5°N,°W°W) continues °C(°C) or higher (lower) for 6 consecutive months or longer. The NINO.3 SST deviation is defined as deviation from the latest sliding What is ENSO? This Section contains explanations for ENSO, El Niño and La Niña as well as a historical account of ENSO related research conducted over the past years. The interaction of the atmosphere and ocean is an essential part of El Niño and La Niña events (the term coupled system is often used to describe the mutual.

STATISTICAL ASPECTS OF ENSO EVENTS () AND THE EL NIlqO-ATLANTIC INTENSE HURRICANE ACTIVITY RELATIONSHIP 1.

El NiñoorLaNiña events are compared with non-ENSO events. After the events are chosen, they are averaged. These averaged events are subtracted from the average of the nonevents to form the composite.

Finally, statistical significance is determined by using a two-tailed Student’s t test, and for the cases evaluated. out of 5 stars A great guide to the philosophy and beauty of Zen Circles of Enlightenment Reviewed in the United States on J As someone who has had a life long interest in Asian martial arts, brush/ink arts, Haiku and Enso(Zen circles), I found this to be an excellent guide to the philosophical aspects of Zen by: 2.

A hierarchy of ENSO (El Niño/Southern Oscillation) prediction schemes has been developed which includes statistical schemes and physical models. The statistical models are, in general, based on advanced statistical techniques and can be classified into models which use either low-frequency variations in the atmosphere (sea level pressure or surface wind) or upper ocean heat Cited by: IRI ENSO Forecast CPC/IRI ENSO Update Published: El Niño/Southern Oscillation (ENSO) Diagnostic Discussion issued jointly by the Climate Prediction Center/NCEP/NWS and the International Research Institute for Climate and Society.

The El Niño-Southern Oscillation (ENSO) is a recurring climate pattern involving changes in the temperature of waters in the central and eastern tropical Pacific Ocean. On periods ranging from about three to seven years, the surface waters across a large swath of the tropical Pacific Ocean warm or cool by anywhere from 1°C to 3°C, compared.

The fact that the SOI is based on the sea level pressure at just two individual stations means it can be affected by shorter-term, day-to-day or week-to-week fluctuations unrelated to ENSO. But averaging the index values over months or seasons helps to isolate more sustained deviations from the average, like those associated with ENSO.

Another limitation of the Southern Oscillation Index is. The Climate Prediction Center (CPC) produces maps of the United States that show probability of precipitation and temperature being above or below normal based on data from previous El Niño Southern Oscillation (ENSO) events.

The year (–) TOGA program was launched to study the predictable cycle of ENSO events in the tropics and their correlation with quasi-stationary features of atmospheric circulation at higher latitudes. One remarkable success of TOGA has been the rapid development of a theoretical.

This is a consequence of interactions of ENSO with the regional seasonal cycle. Some regions have impacts that depend on the magnitude of events. For example, the North European (Baltic) region included on the El Niño map is marked as a cold impact, but very strong El Niño events (e.g. /98, /83) have an opposite warm impact.

The ENSO phenomenon has some substantial effects on world climate; it is associated with risk changes of weather-related disasters such as hurricanes and tropical storms (typhoons), floods and droughts, forest and bush fires, as well as increasing the risk of certain vector-borne diseases such aslong-term climate change may affect the frequency and intensity of weather events.

The Multivariate ENSO Index (MEI) is said to capture a more holistic representation of the atmospheric and oceanic anomalies that occur during ENSO events than do single-variables timeseries like the NinoSST indices. The MEIv2 is based on five variables from the tropical Pacific.

These five variables are: sea-level pressure (P), zonal (U) and. The multivariate ENSO index, abbreviated as MEI, is a method used to characterize the intensity of an El Niño Southern Oscillation (ENSO) event. Given that ENSO arises from a complex interaction of a variety of climate systems, MEI is regarded as the most comprehensive index for monitoring ENSO since it combines analysis of multiple meteorological and oceanographic components.
