| Zusammenfassung |
Mixing of the upper ocean affects the sea surface temperature by bringing
deeper, colder water to the surface. Because even small changes in the
surface temperature can have a large impact on weather and climate,
accurately determining the rate of mixing is of central importance for
forecasting. Although there are several mixing mechanisms, one that has until
recently been overlooked is the effect of turbulence generated by
non-breaking, wind-generated surface waves.
Lately there has been a lot of interest in introducing this mechanism into
ocean mixing models, and real gains have been made in terms of increased
fidelity to observational data. However, our knowledge of the mechanism is
still incomplete. We indicate areas where we believe the existing
parameterisations need refinement and propose an alternative one.
We use two of the parameterisations to demonstrate the effect on the mixed
layer of wave-induced turbulence by applying them to a one-dimensional mixing
model and a stable temperature profile. Our modelling experiment suggests a
strong effect on sea surface temperature due to non-breaking wave-induced
turbulent mixing. |
