Zheng, Yanxin; Li, Shuangling; Keenlyside, Noel Sebastian; He, Shengping; Suo, Lingling (Journal article; Peer reviewed, 2024)Spring consecutive rainfall events (CREs) are key triggers of geological hazards in the Three Gorges Reservoir area (TGR), China. However, previous projections of CREs based on the direct outputs of global climate models ... -
Projecting Wintertime Newly Formed Arctic Sea Ice through Weighting CMIP6 Model Performance and Independence
Zhao, Jiazhen; He, Shengping; Fan, Ke; Wang, Huijun; Li, Fei (Journal article; Peer reviewed, 2024)Precipitous Arctic sea-ice decline and the corresponding increase in Arctic open-water areas in summer months give more space for sea-ice growth in the subsequent cold seasons. Compared to the decline of the entire Arctic ... -
Quantifying the contribution of anthropogenic influence to the East Asian winter monsoon in 1960-2012
Hao, Xin; He, Shengping; Wang, Huijun; Han, Tingting (Peer reviewed; Journal article, 2019-08-07)The East Asian winter monsoon (EAWM) is greatly influenced by many factors that can be classified as anthropogenic forcing and natural forcing. Here we explore the contribution of anthropogenic influence to the change in ... -
Recent Intensified Influence of the Winter North Pacific Sea Surface Temperature on the Mei-Yu Withdrawal Date
Li, Hua; He, Shengping; Fan, Ke; Liu, Yong; Yuan, Xing (Journal article; Peer reviewed, 2021)The mei-yu withdrawal date (MWD) is a crucial indicator of flood/drought conditions over East Asia. It is characterized by a strong interannual variability, but its underlying mechanism remains unknown. We investigated the ... -
Reconciling conflicting evidence for the cause of the observed early 21st century Eurasian cooling
Outten, Stephen; Li, Camille; King, Martin Peter; Suo, Lingling; Siew, Yu Feng; Cheung, Hoffman; Davy, Richard; Dunn-Sigouin, Etienne; Furevik, Tore; He, Shengping; Madonna, Erica; Sobolowski, Stefan Pieter; Spengler, Thomas; Woollings, Tim (Journal article; Peer reviewed, 2023)It is now well established that the Arctic is warming at a faster rate than the global average. This warming, which has been accompanied by a dramatic decline in sea ice, has been linked to cooling over the Eurasian ... -
Relative Impacts of Sea Ice Loss and Atmospheric Internal Variability on the Winter Arctic to East Asian Surface Air Temperature Based on Large-Ensemble Simulations with NorESM2
He, Shengping; Drange, Helge; Furevik, Tore; Wang, Hui-Jun; Fan, Ke; Graff, Lise Seland; Orsolini, Yvan Joseph Georges Emile G. (Journal article; Peer reviewed, 2024)To quantify the relative contributions of Arctic sea ice and unforced atmospheric internal variability to the “warm Arctic, cold East Asia” (WACE) teleconnection, this study analyses three sets of large-ensemble simulations ... -
Role of Atmosphere-ocean-ice Interaction in the Linkage between December Bering Sea Ice and Subsequent February Surface Air Temperature Over North America
Zhao, Jiazhen; He, Shengping; Huijun, Wang (Journal article; Peer reviewed, 2023)This study revealed that the interannual variations of December Bering Sea ice and subsequent February surface air temperature (SAT) over North America are significantly correlated during 2000/01-2020/21, which is not the ... -
The Role of Mid-latitude Westerly Jet in the Impacts of November Ural Blocking on Early-Winter Warmer Arctic-Colder Eurasia Pattern
Xu, Xinping; He, Shengping; Zhou, Botao; Wang, Huijun; Outten, Stephen (Journal article; Peer reviewed, 2022)Based on statistical analysis using observations and idealized model simulations, previous studies have revealed the potential response of early-winter atmospheric circulation and temperature anomalies to November Ural ... -
Sea-ice-loss slowdown modulates the sea surface salinification in the Kara-Laptev Seas since the 2008 summer
Yi, Daling Li; Fan, Ke; He, Shengping; Wang, Peng (Journal article; Peer reviewed, 2024)Recent studies have revealed the slowed Arctic sea-ice loss, but its climate effect on the ocean system remains unclear. By examining reanalysis datasets, we illustrate a paradoxical regime shift characterized by sustained ... -
Simulated and projected relationship between the East Asian winter monsoon and winter Arctic Oscillation in CMIP5 models
Li, Shuo; He, Shengping; Li, Fei; Wang, Huijun (Peer reviewed; Journal article, 2018)Interdecadal change in the relationship between the East Asian winter monsoon (EAWM) and the Arctic Oscillation (AO) has been documented by many studies. This study, utilizing the model outputs from phase 5 of the Coupled ... -
Solar-wind–magnetosphere energy influences the interannual variability of the northern-hemispheric winter climate
He, Shengping; Wang, Huijun; Li, Fei; Li, Hui; Wang, Chi (Journal article; Peer reviewed, 2020)Solar irradiance has been universally acknowledged to be dominant by quasi-decadal variability, which has been adopted frequently to investigate its effect on climate decadal variability. As one major terrestrial energy ... -
Strengthened linkage between November/December North Atlantic Oscillation and subsequent January european precipitation after the late 1980s
Liu, Yang; He, Shengping (Journal article; Peer reviewed, 2020)This work investigates the nonsynchronous relationship between the North Atlantic Oscillation (NAO) and winter European precipitation. The results indicate that the linkage between early-winter (November and December) NAO ... -
