Projections of ocean climate for northwestern Pacific Ocean

The long-term adjustment processes of atmosphere and ocean in response to gradually increased atmospheric CO₂ concentration have been analyzed in 70 and 140 a integrations with NCAR fully-coupled climate system model (CSM).In these experiments the CO₂ concentration has been increased to double and quadruples the initial concentration,respectively.After 70 a,at the time of CO₂ doubling,the model predicts surface air temperature rises by 1.2 and 1.5 K for the globe and the northwestern Pacific Ocean,respectively.The behavior of the quadrupling run is similar:each global and regional mean surface air temperatures increase by 2.8 and 3.0 K at the time of CO₂ quadrupling.From the experiments,surface air temperature changes in the northwestern Pacific Ocean will be more distinctive compared with the global average,mainly due to exceptionally large warming and sea level change near the entrance of the Kuroshio extension.
