abstract = "As an important subject of study, the climate science encompasses
all processes and phenomena in the atmosphere, ocean, ice, and
land, displaying variability over a broad, although well defined,
spectrum of spatial and temporal scales. The disparity of spatial
and temporal scales of climate processes poses a major challenge
in climate modeling, ranging from regional to planetary scales and
from intraseasonal to climate changes over centuries. Moreover,
despite the number of efforts to elucidate prominent phenomena,
certain key features remain elusive, and so preclude actions
toward anticipation and mitigation of hazardous impacts, with
implications over diverse human activities. One interesting
example is the El Niño, La NiñaSouthern Oscillation (ENSO), which
implies in a prominent large-scale coupled oceanatmosphere
oscillation across the equatorial Pacific. ENSO represents the
dominant variability in the climate system on interannual to
decadal timescales. The long-time behavior of the ENSO dynamics,
though, is typically a complex interplay between periodicity and
randomness. The classic approaches cannot precisely characterize
the observed variability, which typically displays structured but
aperiodic oscillations. The irregularity makes difficult to
predict when the next extreme phase of ENSO is going to be
manifested and the peak magnitude of the event has also been a
difficult parameter to predict. Although the theory for ENSO has
been widely explored along the past 40 years by observational and
theoretical work involving different views, there is still lack of
consensus between modelers and observers about what are the
essential mechanisms for ENSO. Recent studies suggest that there
exists El Niño (La Niña) diversity regarding the parameters
related to its amplitude, trigger mechanisms, spatial patterns,
and life cycle as well as its impacts on the globe. Thus, the
objective of the present work is to discuss the development of the
ideas toward what is known about ENSO today. Here, a review on
theoretical fundamentals is presented from ENSO model hierarchy,
basic mechanisms, ENSO irregularity, and interactions with other
scales of variability along with a brief discussion of some recent
observational results.",
