East Asia DecCen: Exploring Decadal to Century Scale Variability and Changes in the East Asian
Climate during the last Millennium A multi-disciplinary study of observed and modelled variations in climate in East Asia, in response to the RCN’s call Climate change – research collaboration with
China
Project leaders: Prof. Tore Furevik, Geophysical Institute and Bjerknes Centre for Climate Research, University
of Bergen, Norway (BCCR-UoB) Prof. Hui-Jun Wang, Institute of Atmospheric Physics/Chinese Academy of Sciences, Beijing,
China
Main objective: To identify regional and remote causes for variations
in temperature, drought and flooding patterns over East Asia, and to
reduce the level of uncertainty in climate projections.
Budget: 7.1 MNOK (7,8 MCNY) for Jul 2009 – Mar 2013

Conclusions
• The SST in North Pacific bridge the spring Arctic sea ice cover and the East Asian summer monsoon precipitation
• The mediating role of SST changes is highlighted by the result that only the AOGCM, but not the AGCM, reproduces the observed sea ice-EASM linkage

• Autumn Arctic sea ice reduction leads to Eurasian cooling. It in turn results in westward extension of EAJS and bridge the AO and EAWM

NAO and Volcanic Eruptions
![Page 28: Exploring Decadal to Century Scale Variability and Changes ...folk.uio.no/kkv/24. Aug/15.15 - 18.00/Parallell A/Gao_Oslo_2015Aug2… · • Module 1 – Project management and coordination](https://reader033.vdocuments.us/reader033/viewer/2022042304/5ed00cce3d1b214f223d5b58/html5/thumbnails/28.jpg)
Volcanic eruptions typically led to strengthened ISM circulation and ISM rainfall at the 3rd year after volcanic eruptions;
External forcing factors, by affecting both the Indian Ocean SST and the winter NAO, could likely produce a stronger statistical but not causal relationship between the winter NAO and the ISM rainfall on inter-decadal timescale.

Conclusion There is a statistical linkage between the
extra-tropical warming and winter Arctic sea ice from 1994 to 2013.
The winter extra-tropical warming (in particular, the warming in the Pacific) can influence the winter Arctic sea ice cover by strengthening the polar vortex and modulating the near surface atmospheric heat transport.
