| 英文摘要 | The ocean could profoundly modulate the ever-increasing atmospheric CO_2 by air-sea CO_2 exchange process,which is also able to cause significant changes of physical and biogeochemical properties in return.In this study,we assessed the long-term average and spatial-temporal variability of global air-sea CO_2 exchange flux(FCO_2) since 1980 s basing on the results of 18 Coupled Model Intercomparison Project Phase 6(CMIP6) Earth System Models(ESMs).Our findings indicate that the CMIP6 ESMs simulated global CO_2 sink in recent three decades ranges from 1.80 to 2.24 Pg C/a,which is coincidence with the results of cotemporaneous observations.What's more,the CMIP6 ESMs consistently show that the global oceanic CO_2 sink has gradually intensified since 1980 s as well as the observations.This study confirms the simulated FCO_2 could reach agreements with the observations in the aspect of primary climatological characteristics,however,the simulation skills of CIMP6 ESMs in diverse open-sea biomes are unevenness.None of the 18 CMIP6 ESMs could reproduce the observed FCO_2 increasement in the central-eastern tropical Pacific and the midlatitude Southern Ocean.Deficiencies of some CMIP6 ESMs in reproducing the atmospheric pressure systems of the Southern Hemisphere and the E1 Ni?o-Southern Oscillation(ENSO)mode of the tropical Pacific are probably the major causes. |
