How Volatile is ENSO? [PDF]

open access: yesSSRN Electronic Journal, 2009
The El Niños Southern Oscillations (ENSO) is a periodical phenomenon of climatic interannual variability, which could be measured through either the Southern Oscillation Index (SOI) or the Sea Surface Temperature (SST) Index.

ENSO theory [PDF]

open access: yesJournal of Geophysical Research: Oceans, 1998
Beginning from the hypothesis by Bjerknes [1969] that ocean‐atmosphere interaction was essential to the El Niño‐Southern Oscillation (ENSO) phenomenon, the Tropical Ocean‐Global Atmosphere (TOGA) decade has not only confirmed this but has supplied detailed theory for mechanisms setting the underlying period and possible mechanisms responsible for the ...

Natuna Off-Shelf Current (NOC) Vertical Variability and Its Relation to ENSO in the North Natuna Sea

open access: yesIlmu Kelautan, 2021
During the northwest monsoon (NWM), southerly flow off the Natuna Islands appeared as the extension of the turning Vietnam coastal jet, known as Natuna off-shelf current (NOC). NOC is generated by the interaction of wind stress and the North Natuna Sea’s

On Sub-ENSO Variability [PDF]

open access: yes, 2006
Multichannel singular spectrum analysis (MSSA) of surface zonal wind, sea surface temperature (SST), 20° isotherm depth, and surface zonal current observations (between 1990 and 2004) identifies three coupled ocean–atmosphere modes of variability in the ...

Annual ENSO

open access: yesJournal of Physical Oceanography, 2003
Abstract Using various observational data, the seasonal cycle of the tropical Pacific is investigated, suggesting the existence of an “annual El Niño–Southern Oscillation (ENSO).” A positive sea surface temperature anomaly (SSTA) appearing off Peru in boreal winter triggers a series of air–sea interactions that consist of westward ...

Interannual variability of the tropical Atlantic independent of and associated with ENSO: Part I. The North Tropical Atlantic [PDF]

open access: yes, 2006
The interannual variability of the tropical Atlantic ocean-atmosphere system is examined using 50 years of sea-surface temperature (SST) and re-analysis data, and satellite data when available.

ENSO Bimodality and Extremes [PDF]

open access: yesGeophysical Research Letters, 2019
AbstractTropical sea surface temperature (SST) and winds vary on a wide range of timescales and have a substantial impact on weather and climate across the globe. Here we study the variability of SST and zonal wind during El Niño‐Southern Oscillation (ENSO) between 1982 and 2014.

Are there statistical links between the direction of European weather systems and ENSO, the solar cycle or stratospheric aerosols? [PDF]

open access: yesRoyal Society Open Science, 2016
The Hess Brezowsky Großwetterlagen (HBGWL) European weather classification system, accumulated over a long period (more than 130 years), provides a rare opportunity to examine the impact of various factors on regional atmospheric flow. We have used these

Why the Southern Hemisphere ENSO responses lead ENSO [PDF]

open access: yesJournal of Geophysical Research: Atmospheres, 2009
Analysis of observational estimates indicates that the El Niño–Southern Oscillation (ENSO) forced pattern in the extratropical Southern Hemisphere (SH), somewhat surprisingly, leads the peak phase of ENSO by one season. A Rossby wave source (RWS) analysis indicates that the tropical and extratropical RWS in the SH develops before the ENSO peak season ...

ENSO dynamics: low-dimensional-chaotic or stochastic? [PDF]

open access: yes, 2012
We apply a test for low-dimensional, deterministic dynamics to the Nino 3 time series for the El Nino Southern Oscillation (ENSO). The test is negative, indicating that the dynamics is high-dimensional/stochastic.
