Atmospheric Circulation & Transport


  • Quantify contribtions to Arctic Amplification from atmospheric large-scale circulation & key regional forcing and feedback processes
  • Identify physical processes and feedback mechanisms which are not adequately represented in climate models, test improved sub-grid scale parametrizations, improve representation of Arctic key processes in coupled and uncoupled cimate models

Overall hypothesis:

  • Large-scale atmosphereic dynamical processes and regional forcing and feedback processes are major drivers of Arctic Amplification.


  • Global and regional cimate models, CIMP5 global model ensemble, reanalysis and satellite data
