| Zusammenfassung |
| We present a new coupled ocean-circulation–ice model
configuration of the Baltic Sea. The model features, contrary to
most existing configurations, a high horizontal resolution of
≈ 1 nautical mile (≈ 1.85 km), which is eddy-resolving over much of the
domain. The vertical discretisation comprises a total of 47 vertical
levels. Results from a 1987 to 1999 hindcast simulation show that
the model's fidelity is competitive. As suggested by a comparison
with sea surface temperatures observed from space, this applies
especially to near-surface processes. Hence, the configuration is
well suited to serve as a nucleus of a fully fledged coupled ocean-circulation–biogeochemical model (which is yet to be
developed). A caveat is that the model fails to reproduce major
inflow events. We trace this back to spurious vertical circulation
patterns at the sills which may well be endemic to high-resolution
models based on geopotential coordinates. Further, we present
indications that – so far neglected – eddy/wind effects exert
significant control on wind-induced up- and downwelling. |
