| Abstract: | In the context of the EU-Project BALANCE () the regional climate model REMO was used for extensive calculations of the Barents Sea climate to investigate the vulnerability
of this region to climate change. The regional climate model REMO simulated the climate change of the Barents Sea Region between
1961 and 2100 (Control and Climate Change run, CCC-Run). REMO on ~50 km horizontal resolution was driven by the transient
ECHAM4/OPYC3 IPCC SRES B2 scenario. The output of the CCC-Run was applied to drive the dynamic vegetation model LPJ-GUESS.
The results of the vegetation model were used to repeat the CCC-Run with dynamic vegetation fields. The feedback effect of
the modified vegetation on the climate change signal is investigated and discussed with focus on precipitation, temperature
and snow cover. The effect of the offline coupled vegetation feedback run is much lower than the greenhouse gas effect. |
