• 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 ...
