      Karypidou, Maria Chara; Sobolowski, Stefan Pieter; Sangelantoni, Lorenzo; Nikulin, Grigory; Katragkou, Eleni (Journal article; Peer reviewed, 2023)
      The region of southern Africa (SAF) is among the most exposed climate change hotspots and is projected to experience severe impacts across multiple economical and societal sectors. For this reason, producing reliable ...
    • 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 (Peer reviewed; Journal article, 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 ...
    • Large‐scale regional model biases in the extra‐tropical North Atlantic storm track and impacts on downstream precipitation

      Global climate models have circulation biases that the community aims to reduce, for instance through high‐resolution dynamical downscaling. We used the Weather Research and Forecasting model (WRF) to downscale both ...
    • 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 (Peer reviewed; Journal article, 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. ...

      Poujol, Basile; Mooney, Priscilla A.; Sobolowski, Stefan Pieter (Peer reviewed; Journal article, 2021)
      Precipitation is changing as the climate warms, and downpours can become more intense due to the increased water holding capacity of the atmosphere. However, the exact nature of the precipitation response and its characteristics ...
