摘要

The mean mass transport induced by surface gravity waves is investigated theoretically for a deep, rotating ocean with a constant eddy viscosity. The waves are periodic in time and have amplitudes that grow or decay slowly in space. The analysis is based on a Lagrangian description of motion, and the results are valid to second order in the wave steepness. An equation for the wave-induced mean Lagrangian mass transport in the oceanic surface layer is derived. It is demonstrated that there are two sources for the mean mass transport: (ⅰ) the form drag associated with the fluctuating wind stress normal to the wave slope and (ⅱ) the horizontal divergence of the mean wave momentum flux. Using a spectral formulation for the wave amplitude, applications related to general ocean circulation models are discussed.

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.
