Control of Barents Sea wintertime cyclone variability by large-scale atmospheric flow
Madonna, Erica; Hes, Gabriel; Li, Camille; Michel, Clio; Siew, Yu Feng (Journal article; Peer reviewed, 2020)Extratropical cyclones transport heat and moisture into the Arctic, which can promote surface warming and sea ice melt. We investigate wintertime cyclone variability in the Barents Sea region to understand what controls ... -
Exploring Arctic-midlatitude teleconnections using observations and numerical models
Siew, Yu Feng (Doctoral thesis, 2021-05-27)The Arctic is warming at a much faster rate than the rest of the globe, with large declines in sea ice, snow cover and permafrost over the last decades. These profound changes have been proposed to influence the midlatitude ... -
Intermittency of Arctic–mid-latitude teleconnections: stratospheric pathway between autumn sea ice and the winter North Atlantic Oscillation
Siew, Yu Feng; Li, Camille; Sobolowski, Stefan Pieter; King, Martin Peter (Journal article; Peer reviewed, 2020)There is an observed relationship linking Arctic sea ice conditions in autumn to mid-latitude weather the following winter. Of interest in this study is a hypothesized stratospheric pathway whereby reduced sea ice in the ... -
North Atlantic Oscillation in winter is largely insensitive to autumn Barents-Kara sea ice variability
Siew, Yu Feng; Li, Camille; Ting, Mingfang; Sobolowski, Stefan Pieter; Wu, Yutian; Chen, Xiaodan (Journal article; Peer reviewed, 2021)Arctic sea ice extent in autumn is significantly correlated with the winter North Atlantic Oscillation (NAO) in the satellite era. However, questions about the robustness and reproducibility of the relationship persist. ... -
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 ...
