Impact of near-term climate forcing on the Arctic Oscillation
Near-term climate forcers (NTCFs), including aerosols and chemically reactive gases, influence both climate and air quality. However, the impact of NTCFs on internal climate variability is unclear. This study investigates how reductions in NTCFs affect Arctic Oscillation (AO) in the near future, using the Aerosol and Chemistry Model Intercomparison Project. Reduced NTCFs increase the occurrence of the positive AO in the near-future period. We sug…
Changes in the role of Pacific decadal oscillation on East Asian winter surface temperature
The complex interaction between the Pacific decadal oscillation (PDO) and East Asian winter temperatures remains unclear. This study reveals that since the early 2000s, East Asia has experienced a strengthening of Aleutian low (AL) and Siberian high (SH) during negative PDO phases, leading to an intensified East Asian winter monsoon (EAWM). The increased pressure gradient between the SH and the AL, driven by warming in the western Pacific associa…
Variability of upper troposphere–lower stratosphere ozone over East Asia from a perspective of atmospheric stationary waves
By analyzing observational reanalysis datasets since the late 20th century, in this study we investigated the monthly variability of East Asian ozone at the upper troposphere–lower stratosphere (UTLS, 250 hPa), from a perspective of atmospheric stationary waves. To identify the primary modes of East Asian UTLS ozone variability, an empirical orthogonal function (EOF) analysis was conducted, revealing that the first three EOF modes account for app…
Earlier carbon neutrality more effectively limits heat exposure of urban populations in developing continents
Achieving carbon neutrality by the 2050s, as proposed in the Paris Agreement, is imperative for mitigating climate risks and fostering a sustainable future. Here, by examining the multi-model projections under the Coupled Model Intercomparison Project Phase 6 shared socioeconomic pathway scenarios, we show that achieving carbon neutrality by the 2050s shared socioeconomic pathway (SSP) 1-1.9 can reduce global population exposure (PE) to hot tempe…
Enso response depending on the state of the North Atlantic under a net-zero carbon emission scenario
Understanding the response of the El Niño-Southern Oscillation (ENSO) in a net-zero carbon emission scenario is critical for correctly projecting future climate variability after the Paris Agreement. This study examines the behavior of ENSO using the Community Earth System Model version 2, in which a 400 year simulation was performed, following the SSP5-8.5 pathway, then gradually reducing CO 2 emissions to net-zero with stabilization period. Aft…
Regionally asymmetric hysteresis of western North Pacific tropical cyclone activity in a CO 2 removal experiment
Tropical cyclones (TCs) are devastating natural phenomena with considerable socio-economic impacts on coastal regions worldwide. Despite their importance for climate mitigation and adaptation planning, the response of TC activity to carbon dioxide removal (CDR) has received limited attention. Here, we examine the influence of CDR on TC activity over the western North Pacific (WNP) using an Earth system model under an idealized CDR scenario. Our r…
Role of the Warm Arctic Cold Eurasian-like pattern on the near future warming rate of East Asian surface temperature
Internal climate variability (ICV) plays an important role in either accelerating or slowing down the rate of surface temperature warming in East Asia in the near future. To examine the influence of ICV on East Asian surface temperature in the near future, we mainly analyzed the data sets obtained from Max Planck Institute Grand Ensemble model simulations under the Representative Concentration Pathway 8.5 scenario. It is found that the ICV associ…
Asymmetric Enso teleconnections in a symmetric CO 2 concentration pathway
El Niño-Southern Oscillation (ENSO) is the strongest interannual phenomenon occurring in the tropical Pacific, significantly affecting the entire world. The ENSO response to increasing CO 2 concentrations have been extensively studied, but the reverse scenario is still not well understood. Here, we investigate the hysteresis of ENSO teleconnections in a CO 2 removal simulation of an earth system model. During the ramp-up period of CO 2 concentrat…
Physically based equation representing the forcing-driven precipitation in climate models
This study aims to improve our understanding of the response of precipitation to forcings by proposing a physically-based equation that resolves simulated precipitation based on the atmospheric energy budget. The equation considers the balance between latent heat release by precipitation and the sum of the slow response by tropospheric temperature changes and the fast response by abrupt radiative forcing (RF) changes. The equation is tuned with t…
Distinct impacts of two types of El Niño events on northern winter high-latitude temperatures simulated by CMIP6 climate models
The interannual variability of the Northern Hemisphere winter climate is strongly linked to the El Niño-Southern Oscillation (ENSO). While North Pacific and North America often exhibit a robust response to ENSO, so-called the Pacific–North America (PNA) pattern, the Arctic and Eurasian climate responses to ENSO remain elusive. This study examines 40 different climate models from the Coupled Model Intercomparison Project Phase 6 (CMIP6) to find th…
Impact of volcanic eruptions on extratropical atmospheric circulations
Understanding the impacts of volcanic eruptions on the atmospheric circulations and surface climate in the extratropics is important for inter-annual to decadal climate prediction. Previous studies on the Northern Hemisphere climate responses to volcanic eruptions have shown that volcanic eruptions likely induce northern Eurasian warming through the intensified Arctic polar vortex in the stratosphere and the positive phase of Arctic Oscillation/N…
Attribution of the 2015 record high sea surface temperatures over the central equatorial Pacific and tropical Indian Ocean
This study assessed the anthropogenic contribution to the 2015 record-breaking high sea surface temperatures (SSTs) observed in the central equatorial Pacific and tropical Indian Ocean. Considering a close link between extreme warm events in these regions, we conducted a joint attribution analysis using a fraction of attributable risk approach. Probability of occurrence of such extreme anomalies and long-term trends for the two oceanic regions we…
