| Based on a set of climate simulations utilizing two kinds of Earth system models (ESMs) in which observed ocean hydrographic data are assimilated using exactly the same data assimilation procedure, we have clarified that the successful simulation of the observed air-sea CO2 flux variations in the equatorial Pacific is tightly linked to the reproducibility of coupled physical air-sea processes. When an ESM with a weaker ENSO (El Nino-Southern Oscillations) amplitude than that of the observations was used for historical simulations with ocean data assimilation, the observed equatorial anticorrelated relationship between the sea surface temperature (SST) and the air-sea CO2 flux on interannual to decadal timescales could not be represented. The simulated CO2... |
