  • Variability of upper troposphere–lower stratosphere ozone over East Asia from a perspective of atmospheric stationary waves

    Open AccessJae‐Heung Park, Su-Jung Lee et al.ARTICLEEnvironmental Research Letters2025

    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…

  • Hysteresis of European summer precipitation under a symmetric CO 2 ramp-up and ramp-down pathway

    Open AccessNari Im, Daehyun Kim et al.ARTICLEEnvironmental Research Letters2024

    This study investigates the mechanism of the hysteresis of European summer mean precipitation in a CO 2 removal (CDR) simulation. The European summer mean precipitation exhibits robust hysteresis in response to the CO 2 forcing; after decreasing substantially (∼40%) during the ramp-up period, it shows delayed recovery during the ramp-down period. We found that the precipitation hysteresis over Europe is tied to the hysteresis in the Atlantic Meri…

  • Precipitation-induced abrupt decrease of Siberian wildfire in summer 2022 under continued warming

    Open AccessYeonsoo Cho, Jin‐Ho Yoon et al.ARTICLEEnvironmental Research Letters2024

    Wildfires in Northeast (NE) Siberia have become more frequent owing to the warming climate, exerting a profound impact on the global carbon cycle. While an increase in global temperature is recognized as a primary driver of unprecedented wildfires, the role of precipitation during wildfire season is relatively unexplored. Here, we present evidence that an increase in summer precipitation led to a sudden decrease in NE Siberian wildfires, especial…

  • Asymmetric Enso teleconnections in a symmetric CO 2 concentration pathway

    Open AccessSoon‐Il An, Su-hyeon Shin et al.ARTICLEEnvironmental Research Letters2024

    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…

  • Intensified surface chlorophyll responses to the Indian Ocean Dipole under greenhouse warming

    Open AccessGayan Pathirana, Kyung Min Noh et al.ARTICLEEnvironmental Research Letters2024

    The Indian Ocean Dipole (IOD) has been proposed to be a key driver of biological processes in the Indian Ocean (IO) in the present climate. Given the expected influence of global warming on both the properties of the IOD and the biogeochemistry within the IO, a key question arises: How will the relationship between the IOD and surface chlorophyll evolve in a warming climate? Here, utilizing simulations from the Coupled Model Intercomparison Proje…

  • A biological dipole variability in the Indian Ocean

    Open AccessGayan Pathirana, Kyung Min Noh et al.ARTICLEEnvironmental Research Letters2023

    The Indian Ocean Dipole (IOD) is a prominent mode of climate variability in the tropical Indian Ocean (IO). It exerts a significant influence on biological activities in this region. To elucidate the biological response to the IOD, previous research has introduced the biological dipole mode index (BDMI). However, the delineation of the region by the BDMI has limitations in capturing IOD-induced chlorophyll variations in the IO. By analyzing obser…

  • Phytoplankton responses to increasing Arctic river discharge under the present and future climate simulations

    Open AccessJung Hyun Park, Seong‐Joong Kim et al.ARTICLEEnvironmental Research Letters2023

    In recent decades, the unprecedented rate of Arctic warming has accelerated the high-latitude landmass hydrological cycle, leading to increased river discharge into the Arctic Ocean. This study elucidates the role of Arctic river discharge, which was the large model uncertainty in the Coupled Model Intercomparison Project 6, for the phytoplankton responses in present-day and future climate simulations by adding fresh water into the model. In the …

  • Impact of volcanic eruptions on extratropical atmospheric circulations

    Open AccessSeungmok Paik, Seung‐Ki Min et al.ARTICLEEnvironmental Research Letters2023

    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…

  • Global chlorophyll responses to marine heatwaves in satellite ocean color

    Open AccessKyung Min Noh, Hyung‐Gyu Lim et al.ARTICLEEnvironmental Research Letters2022

    Marine heatwaves (MHWs), prolonged ocean temperature extremes, have been enhanced by global warming in recent decades. More intense and longer MHWs have increasingly negative impacts on marine organisms that threaten their resilience of marine ecosystems. In this study, we investigated global marine phytoplankton biomass (chlorophyll) estimated by satellite ocean color and its response to MHWs on global and regional scales. We find that MHWs typi…

  • Antarctic meltwater-induced dynamical changes in phytoplankton in the Southern Ocean

    Open AccessJi‐Hoon Oh, Kyung Min Noh et al.ARTICLEEnvironmental Research Letters2021

    It has been suggested that the freshwater flux due to the recent melting of the Antarctic ice-sheet/shelf will suppress ventilation in the Southern Ocean (SO). In this study, we performed idealized earth-system simulations to examine the impacts of Antarctic meltwater on the biomass of surface phytoplankton in the Antarctic Ocean. The enhanced stratification due to the meltwater leads to a decrease in surface nitrate concentration, but an increas…

  • Effects of Pacific Intertropical Convergence Zone precipitation bias on Enso phase transition

    Open AccessYoo‐Geun Ham, Yoo-Geun Ham et al.ARTICLEEnvironmental Research Letters2014

    In this study, the effect of mean precipitation bias over the Pacific Intertropical Convergence Zone (ITCZ) on the El Nino southern oscillation (ENSO) transition is examined using CMIP3 and CMIP5 archives. It is found that the climate models with excessive mean precipitation over the central/eastern Pacific ITCZ tend to simulate slower phase transition of the ENSO. This is because a wetter climatology provides a favorable condition for anomalousl…

  • Intensified Arctic warming under greenhouse warming by vegetation–atmosphere–sea ice interaction

    Open AccessJee‐Hoon Jeong, Jee-Hoon Jeong et al.ARTICLEEnvironmental Research Letters2014

    Observations and modeling studies indicate that enhanced vegetation activities over highlatitudes under an elevated CO2 concentration accelerate surface warming by reducing thesurface albedo. In this study, we suggest that vegetation-atmosphere-sea ice interactions overhigh latitudes can induce an additional amplification of Arctic warming. Our hypothesis is testedby a series of coupled vegetation-climate model simulations under 2xCO2 environment…

  • Improvement in simulation of Eurasian winter climate variability with a realistic Arctic sea ice condition in an atmospheric GCM

    Open AccessYoung‐Kwon Lim, Young-Kwon Lim et al.ARTICLEEnvironmental Research Letters2012

    The present study investigates how much a realistic Arctic sea ice condition can contribute to improve simulation of the winter climate variation over the Eurasia region. Model experiments are set up using different sea ice boundary conditions over the past 24 years (i.e., 1988-2011). One is an atmospheric model inter-comparison (AMIP) type of run forced with observed sea-surface temperature (SST), sea ice, and greenhouse gases (referred to as Ex…

  • Improved simulation of two types of El Niño in CMIP5 models

    Open AccessJong‐Seong Kug, Yoo‐Geun Ham et al.ARTICLEEnvironmental Research Letters2012

    Using the coupled general circulation models (CGCMs) participating in phases 3 and 5 of the Coupled Model Intercomparison Project (CMIP3 and CMIP5), simulations of the two types of El Niño event are evaluated. Previous studies using CMIP3 models pointed out that most of the models tend to simulate a single type of El Niño, and have serious problems in simulating the two types of El Niño independently. On the average, the CGCMs in CMIP5 have sligh…
