摘要

[1]Three ocean general circulation models and a climate model are employed to evaluate the influences of the nonbreaking surface wave-induced mixing on the austral summer (December-January-February) mixed layer in the Southern Ocean. These models use either the Meljor-Yamada turbulence closure scheme or the K profile parameterization scheme. The numerical results show that the nonbreaking surface wave-induced mixing can reduce sea surface temperature and increase subsurface temperature of the upper ocean, which can deepen the upper ocean mixed layer. For these four models, austral summer mixed-layer depths in the cases with the wave-induced mixing deepen by 6.2-21.5 m than those without in the Southern Ocean (30S-65S), much closer to the observation. These results indicate that incorporation of the wave-induced mixing can improve the simulation of the austral summer upper mixed layer in the Southern Ocean. Although the responses of four models are different, all simulation results show notable improvements, which may imply that the nonbreaking surface wave-induced mixing is an indispensable physical process for ocean and climate models.

7. The oceans mediate the response of global climate to natural and anthropogenic forcings. Yet for the past 2,000 years — a key interval for understanding the present and future climate response to these forcings — global sea surface temperature changes and the underlying driving mechanisms are poorly constrained. Here we present a global synthesis of sea surface temperatures for the Common Era (ce) derived from 57 individual marine reconstructions that meet strict quality control criteria. We observe a cooling trend from 1 to 1800 ce that is robust against explicit tests for potential biases in the reconstructions. Between 801 and 1800 ce, the surface cooling trend is qualitatively consistent with an independent synthesis of terrestrial temperature reconstructions, and with a sea surface temperature composite derived from an ensemble of climate model simulations using best estimates of past external radiative forcings. Climate simulations using single and cumulative forcings suggest that the ocean surface cooling trend from 801 to 1800 ce is not primarily a response to orbital forcing but arises from a high frequency of explosive volcanism. Our results show that repeated clusters of volcanic eruptions can induce a net negative radiative forcing that results in a centennial and global scale cooling trend via a decline in mixed-layer oceanic heat content.
