    • Assessing the influence of sea surface temperature and arctic sea ice cover on the uncertainty in the boreal winter future climate projections 

      Cheung, Ho-Nam; Keenlyside, Noel Sebastian; Koenigk, Torben; Yang, Shuting; Tian, Tian; Xu, Zhiqing; Gao, Yongqi; Ogawa, Fumiaki; Omrani, Nour-Eddine; Qiao, Shaobo; Zhou, Wen (Journal article; Peer reviewed, 2022)
      We investigate the uncertainty (i.e., inter-model spread) in future projections of the boreal winter climate, based on the forced response of ten models from the CMIP5 following the RCP8.5 scenario. The uncertainty in the ...

    • Evaluating Impacts of Recent Arctic Sea Ice Loss on the Northern Hemisphere Winter Climate Change 

      Ogawa, Fumiaki; Keenlyside, Noel; Gao, Yongqi; Koenigk, Torben; Yang, Shuting; Suo, Lingling; Wang, Tao; Gastineau, Guillaume; Nakamura, Tetsu; Cheung, Ho Nam; Omrani, Nour-Eddine; Ukita, Jinro; Semenov, Vladimir (Journal article; Peer reviewed, 2018)
      Wide disagreement among individual modeling studies has contributed to a debate on the role of recent sea ice loss in the Arctic amplification of global warming and the Siberian wintertime cooling trend. We perform coordinated ...

    • Factors affecting extreme rainfall events in the South Pacific 

      Pariyar, Sunil Kumar; Keenlyside, Noel; Sorteberg, Asgeir; Spengler, Thomas; Bhatt, Bhuwan Chandra; Ogawa, Fumiaki (Journal article; Peer reviewed, 2020)
      Extreme rainfall events in the South Pacific are widespread and affected by various factors on different time scales. We use daily rainfall data from 20 stations over the South Pacific to investigate the characteristics ...

    • Mitigating climate biases in the midlatitude North Atlantic by increasing model resolution: SST gradients and their relation to blocking and the jet 

      Athanasiadis, Panos J.; Ogawa, Fumiaki; Omrani, Nour-Eddine; Keenlyside, Noel Sebastian; Schiemann, Reinhard; Baker, Alexander J.; Vidale, Pier Luigi; Bellucci, Alessio; Ruggieri, Paolo; Haarsma, Rein; Roberts, Malcolm J.; Roberts, Chris; Novak, Lenka; Gualdi, Silvio (Journal article; Peer reviewed, 2022)
      Starting to resolve the oceanic mesoscale in climate models is a step change in model fidelity. This study examines how certain obstinate biases in the midlatitude North Atlantic respond to increasing resolution (from 1° ...

    • Oceanic forcing of the global warming slowdown in multi-model simulations 

      Xu, Xinping; He, Shengping; Furevik, Tore; Gao, Yongqi; Wang, Huijun; Li, Fei; Ogawa, Fumiaki (Journal article; Peer reviewed, 2020)
      Abstract Concurrent with the slowdown of global warming during 2002–2013, the wintertime land surface air temperatures over Eurasia, North America, Africa, Australia, South America, and Greenland experienced notable ...

    • Pacific oceanic front amplifies the impact of Atlantic oceanic front on North Atlantic blocking 

      Cheung, Ho Nam; Omrani, Nour-Eddine; Ogawa, Fumiaki; Keenlyside, Noel Sebastian; Nakamura, Hisashi; Zhou, Wen (Journal article; Peer reviewed, 2023)
      Atmospheric blocking is a crucial driver of extreme weather events, but its climatological frequency is largely underestimated in state-of-the-art climate models, especially around the North Atlantic. While air-sea interaction ...
