A new conceptual model for ENSO has been constructed based upon the positive feedback of tropical ocean–atmosphere interaction proposed by Bjerknes as growth mechanism and recharge–discharge equatorial heat content phase-transition suggested Cane Zebiak Wyrtki. This combines SST dynamics ocean adjustment into a coupled basinwide recharge oscillator that relies on nonequilibrium between zonal mean thermocline depth wind stress. Over wide range relative coupling coefficient, this can be either...
Abstract In this study, two types of El Niño events are classified based on spatial patterns the sea surface temperature (SST) anomaly. One is cold tongue (CT) Niño, which can be regarded as conventional and other warm pool (WP) Niño. The CT characterized by relatively large SST anomalies in Niño-3 region (5°S–5°N, 150°–90°W), while WP associated with mostly confined to Niño-4 160°E–150°W). addition, many atmospheric oceanic variables also distinctively different for events. Furthermore,...
Abstract El Niño–Southern Oscillation (ENSO) is a naturally occurring mode of tropical Pacific variability, with global impacts on society and natural ecosystems. While it has long been known that Niño events display diverse range amplitudes, triggers, spatial patterns, life cycles, the realization ENSO’s can be highly sensitive to this event-to-event diversity driving renewed interest in subject. This paper surveys our current state knowledge ENSO diversity, identifies key gaps...
Beginning from the hypothesis by Bjerknes [1969] that ocean‐atmosphere interaction was essential to El Niño‐Southern Oscillation (ENSO) phenomenon, Tropical Ocean‐Global Atmosphere (TOGA) decade has not only confirmed this but supplied detailed theory for mechanisms setting underlying period and possible responsible irregularity of ENSO. Essentials ocean dynamical adjustment are reviewed an ENSO perspective. Approaches simple atmospheric modeling greatly aided development feedbacks...
The Asian summer monsoon affects more than sixty percent of the world's population; understanding its controlling factors is becoming increasingly important due to expanding human influence on environment and climate need adapt global change. Various mechanisms have been suggested; however, an overarching paradigm delineating dominant for generation strength remains debated. Here we use observation data numerical experiments demonstrates that systems are controlled mainly by thermal forcing...
How to predict the year‐to‐year variation of east Asian summer monsoon (EASM) is one most challenging and important tasks in climate prediction. It has been recognized that EASM variations are intimately but not exclusively linked development decay El Niño or La Niña. Here we present observed evidence numerical experiment results show anomalous North Atlantic Oscillation (NAO) spring (April–May) can induce a tripole sea surface temperature pattern persists into ensuing excite downstream...
El Nino events (warm) are often stronger than La Nina (cold). This asymmetry is an intrinsic nonlinear characteristic of the Nino-Southern Oscillation (ENSO) phenomenon. In order to measure nonlinearity ENSO, maximum potential intensity (MPI) index and dynamic heating (NDH) ENSO proposed as qualitative quantitative measures. The 1997/98 that was recorded strongest event in past century another strong 1982/83 nearly reached MPI. During these superwarming events, normal climatological...
The source of irregularity in El Niño, the large interannual climate variation Pacific ocean-atmosphere system, has remained elusive. Results from an Niño model exhibit transition to chaos through a series frequency-locked steps created by nonlinear resonance with Earth's annual cycle. overlapping these resonances leads chaotic behavior. This scenario explains number results and produces spectral characteristics consistent currently available data.
The conceptual recharge oscillator model intuitively established in Part I is derived from a dynamical framework of Cane–Zebiak type for tropical ocean–atmosphere interaction. A two-strip approximation to the equatorial ocean dynamics and one-strip SST are employed obtain stripped-down coupled that captures main physics model. It shown can be obtained with two-box zonal direction or low-frequency filter out high-frequency modes. Linear solutions analytically solved dependence modes on...
The global response to tropical heating is studied by performing a time integration of 15-level primitive equation model, starting with basic flow maintained constant forcing. direct, quasi-steady the seen during first 20 days before baroclinic instability dominates. This technique enables investigation variety flows, from resting state December–February 3D time-mean flow; timescales for establishing remote responses; and nonlinear effects. It also allows determination establishment...
[1] El Niño-Southern Oscillation (ENSO), which dominates variability on interannual timescale in the climate system, is known to exhibit various spatio-temporal characteristics. Recent studies show that additional a canonical Niño with its major center of sea surface temperatures (SST) anomalies equatorial Pacific cold-tongue region, different type action shifted warm-pool edge has emerged and become more common during past two decades. Because SST patterns these types events are highly...
Abstract Climate variability in the tropical Indo-Pacific sector has undergone dramatic changes under global ocean warming. Extreme Indian Ocean dipole (IOD) events occurred repeatedly recent decades with an unprecedented series of three consecutive episodes during 2006–08, causing vast climate and socioeconomic effects worldwide weakening historic El Niño–Indian monsoon relationship. Major attention been paid to Niño influence on Ocean, but how IOD influences its predictability remained...
Abstract The twentieth century Northern Hemisphere mean surface temperature (NHT) is characterized by a multidecadal warming‐cooling‐warming pattern followed flat trend since about 2000 (recent warming hiatus). Here we demonstrate that the North Atlantic Oscillation (NAO) implicated as useful predictor of NHT variability. Observational analysis shows NAO leads both detrended and oceanic Multidecadal (AMO) 15–20 years. Theoretical illuminates precedes variability through its delayed effect on...
Abstract Observational analysis suggests that the western tropical Pacific (WTP) sea surface temperature (SST) shows predominant variability over multidecadal time scales, which is unlikely to be explained by Interdecadal Oscillation. Here we show this largely remote Atlantic oscillation (AMO). A suite of Pacemaker experiments successfully reproduces WTP and AMO–WTP SST connection. The AMO warm anomaly generates an atmospheric teleconnection North Pacific, weakens Aleutian low subtropical...
