Four groups of the AGCM experiments are conducted to isolate the relative role of the Arctic sea ice, PDO and AMO in Arctic warming. One is a historical experiment and the other three adopt the boundary conditions with climatological Arctic sea ice, removal of PDO / AMO signals in SST, respectively.
The preliminary results show that the Arctic sea ice trend contributes to the majority of Arctic near-surface warming while PDO suppresses Arctic tropospheric warming in recent several decades. The contribution of AMO is uncertain.
