Most El Niño events occur sporadically and peak in a single winter1-3, whereas La Niña tends to develop after an last for two years or longer4-7. Relative single-year Niña, consecutive features meridionally broader easterly winds hence slower heat recharge of the equatorial Pacific6,7, enabling cold anomalies persist, exerting prolonged impacts on global climate, ecosystems agriculture8-13. Future changes multi-year-long remain unknown. Here, using climate models under future greenhouse-gas...
Abstract El Niño-Southern Oscillation (ENSO) features strong warm events in the eastern equatorial Pacific (EP), or mild and cold central (CP), with distinct impacts on global climates. Under transient greenhouse warming, models project increased sea surface temperature (SST) variability of both ENSO regimes, but timing emergence out internal remains unknown for either regime. Here we find EP-ENSO SST emerging by around 2030 ± 6, more than a decade earlier that CP-ENSO, approximately four...
Abstract Antarctic shelf ocean warming affects melt of ice shelf/sheets and sea but projected changes vary vastly across climate models. A increase in El Niño variability has been found to slow future mid-latitude Southern Ocean how this impacts the is unknown. Here we show that a accelerates warming, hastening shelf/sheet slowing reduction.
North Tropical Atlantic Ocean variability increases in a warming climate due to an enhanced El Niño–Southern Oscillation influence.
Under transient greenhouse warming, El Niño-Southern Oscillation (ENSO) is projected to increase pre-2100, accompanied by an easier establishment of atmospheric convection in the equatorial eastern Pacific, where sea surface temperature (SST) warms faster than surrounding regions. After 2100, how ENSO variability may change remains unknown. Here we find that under a high emission scenario, post-2100 reverses from initial amplitude far smaller 20
Abstract The El Niño/Southern Oscillation is characterized by irregular warm (El Niño) and cold (La Niña) events in the tropical Pacific Ocean, which have substantial global environmental socioeconomic impacts. These are generally attributed to instability of basin-scale air–sea interactions equatorial Pacific. However, role sub-basin-scale processes life cycle remains unknown due scarcity observations coarse resolution climate models. Here, using a long-term high-resolution simulation, we...
Abstract The El Niño Southern Oscillation (ENSO) is a significant interannual phenomenon that occurs every 2-7 years in the tropical Pacific and has global climate impacts linked to natural disasters. Understanding accurately modelling ENSO dynamics crucial for predicting its understanding characteristics of itself, such as amplitude, periodicity, spatial pattern. However, latest version Australian model ACCESS-CM2 (CM2), simulated mainly displays quasi-biennial oscillations (around 2-2.5...
Simulating accurately the South Asian summer monsoon is crucial for food security of several countries yet challenging global climate models (GCMs). The GCMs suffer from some systematic biases including dry bias in mean rainfall over India subcontinent and excessive equatorial light rain between which relationship was rarely discussed. Numerical experiments are conducted one month during active with quasi-uniform resolution 60 km (U60 km) 3 (U3 separately. Evaluation observations shows that...
Abstract The recharge oscillator (RO) is a simple mathematical model of the El Niño Southern Oscillation (ENSO). In its original form, it based on two ordinary differential equations that describe evolution equatorial Pacific sea surface temperature and oceanic heat content. These make use physical principles operate in nature: (a) air‐sea interaction loop known as Bjerknes feedback, (b) delayed feedback arising from slow response to winds within band, (c) state‐dependent stochastic forcing...
Abstract Changes of the Pacific decadal oscillation (PDO) under global warming are investigated by using outputs from phase 5 Coupled Model Intercomparison Project (CMIP5) and a theoretical midlatitude air–sea coupled model. In climate, variability PDO is found to be significantly suppressed, with amplitude reduced cycle shifted toward higher-frequency band. We used model put forward Goodman Marshall (herein GM model) underpin potential mechanisms. The exhibits growing mode that resembles...
Abstract Increasing climate model resolution offers multifaceted benefits, such as improving modeled tropical cyclones. However, the extent to which it benefits El Niño‐Southern Oscillation (ENSO) simulation remains unknown. Here, comprehensive information on sensitivity of ENSO performance various resolutions is provided, based a multi‐model and multi‐resolution ensemble global coupled models. Overall, reduced biases equatorial sea surface temperature (SST) precipitation mean state in...
Abstract Observed El Niño–Southern Oscillation (ENSO) events exhibit distinct amplitude and evolution asymmetries due to nonlinear interactions between sea surface temperature (SST), equatorial zonal wind stress, thermocline depth anomalies. Establishment of atmospheric convection leads a response winds SST, but its relative importance oceanic feedbacks remains unclear. Using recharge oscillator model modified incorporate various nonlinearities estimated from observations, we show that the...
Abstract The El Niño‐Southern Oscillation (ENSO) has two distinct regimes, one in the eastern Pacific (EP) featuring strong Niño and other central (CP) characterized by La Niña. Establishment of atmospheric convection climatologically cold dry EP region provides a major source nonlinearity, but its role relationship between CP‐ EP‐ENSO variability their long‐term change remain unclear. By constructing nonlinear two‐box recharge‐oscillator model, here we show that operates to boost Niño, CP...
Abstract The westerly wind burst (WWB) is an important triggering mechanism of El Niño and typically occurs in the western Pacific Ocean. Fourier spectrum field over tropical characterised by a large variety peaks distributed from intra-seasonal to decadal time scales, suggesting that WWBs could be result nonlinear interactions on these scales. Using combination observations simulations with 15 coupled models Coupled Model Intercomparison Project Phase 6 (CMIP6), we demonstrate main drivers...
Abstract Recent research has shown that there is a projected increase in the frequency of strong positive Indian Ocean dipole (spIOD) events terms both sea surface temperature (SST) and precipitation. However, it not clear whether spIOD defined by SST precipitation, hereafter referred to as SST-spIOD Pr-spIOD events, respectively, will at same pace under greenhouse warming. Using climate models from phase 5 Coupled Model Intercomparison Project (CMIP5) CMIP6 can reasonably simulate here we...
