Behaviourally modern humans in coastal southern Africa experienced an increasingly continental climate during the transition from Marine Isotope Stage 5 to 4
Göktürk, Ozan Mert; Simon, Margit Hildegard; Sobolowski, Stefan Pieter; Zhang, Zhongshi; van der Bilt, Willem Godert Maria; Mørkved, Pål Tore; D’Andrea, William J.; Niekerk, Karen Loise van; Henshilwood, Christopher Stuart; Armitage, Simon James; Jansen, Eystein (Journal article; Peer reviewed, 2023-07-25)Unravelling evolution-by-environment interactions on the gut microbiome is particularly relevant considering the unprecedented level of human-driven disruption of the ecological and evolutionary trajectories of species. ... -
Circulation responses to surface heating and implications for polar amplification
Siew, Peter Y.F.; Li, Camille; Sobolowski, Stefan Pieter; Dunn-Sigouin, Etienne; Ting, Mingfang (Journal article; Peer reviewed, 2024)A seminal study by Hoskins and Karoly (1981) explored the atmospheric circulation response to tropospheric heating perturbations at low latitudes and midlatitudes. Here we revisit and extend their study by investigating ... -
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 ... -
Large‐scale regional model biases in the extra‐tropical North Atlantic storm track and impacts on downstream precipitation
Pontoppidan, Marie Louise Nielsen; Kolstad, Erik Wilhelm; Sobolowski, Stefan Pieter; Sorteberg, Asgeir; Changhai, Liu; Rasmussen, Roy (Peer reviewed; Journal article, 2019)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 (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 ... -
Resampling of ENSO teleconnections: accounting for cold-season evolution reduces uncertainty in the North Atlantic
King, Martin Peter; Li, Camille; Sobolowski, Stefan Pieter (Journal article; Peer reviewed, 2021)We re-examine the uncertainty of the El Niño–Southern Oscillation (ENSO) teleconnection to the North Atlantic following the investigation of Deser et al. (2017) (DES2017). Our analyses are performed on the November–December ... -
Sensitivity of coastal southern African climate to changes in coastline position and associated land extent over the last glacial
Göktürk, Ozan Mert; Sobolowski, Stefan Pieter; Simon, Margit Hildegard; Zhang, Zhongshi; Jansen, Eystein (Journal article; Peer reviewed, 2023)Paleoclimatic changes in South Africa, especially around the southern Cape region, are of intense interdisciplinary interest; as this is an important area in the context of human evolution, hosting several prominent ... -
Toward a multi-faceted conception of co-production of climate services
Bremer, Scott; Wardekker, Arjan; Dessai, Suraje; Sobolowski, Stefan Pieter; Slaattelid, Rasmus Tore; van der Sluijs, Jeroen P (Journal article; Peer reviewed, 2019-02-11)Increasing numbers of scholars and practitioners appeal to procedural theories of ‘co-production’ as they work to transform climate science into climate services. Most work in this direction theorises co-production as an ... -
Trials, errors and improvements in co-production of climate services
Kolstad, Erik Wilhelm; Sofienlund, Oda Nærland; Kvamsås, Hanna; Stiller-Reeve, Mathew Alexander; Neby, Simon; Paasche, Øyvind; Pontoppidan, Marie Louise Nielsen; Sobolowski, Stefan Pieter; Haarstad, Håvard; Oseland, Stina Ellevseth; Omdahl, Lene; Waage, Snorre (Peer reviewed; Journal article, 2019)Climate change yields both challenges and opportunities. In both cases, costly adaptations and transformations are necessary and desirable, and these must be based on realistic and relevant climate information. However, ...
