| Zusammenfassung |
| An established one-dimensional (1-D) model of Shelf Sea Physics and Primary
Production (S2P3) is adapted for flexible use in selected regional settings
over selected periods of time. This Regional adaptation of S2P3, the S2P3-R
framework (v1.0), can be efficiently used to investigate physical and
biological phenomena in shelf seas that are strongly controlled by vertical
processes. These include spring blooms that follow the onset of
stratification, tidal mixing fronts that seasonally develop at boundaries
between mixed and stratified water, and sub-surface chlorophyll maxima that
persist throughout summer. While not representing 3-D processes, S2P3-R
reveals the horizontal variation of the key 1-D (vertical) processes. S2P3-R
should therefore only be used in regions where horizontal processes –
including mean flows, eddy fluxes and internal tides – are known to exert a
weak influence in comparison with vertical processes. In such cases, S2P3-R
may be used as a highly versatile research tool, alongside more complex and
computationally expensive models. In undergraduate oceanography modules and
research projects, the model serves as an effective practical tool for
linking theory and field observations. Three different regional
configurations of S2P3-R are described, illustrating a range of diagnostics,
evaluated where practical with observations. The model can be forced with
daily meteorological variables for any selected year in the reanalysis era
(1948 onwards). Example simulations illustrate the considerable extent of
synoptic-to-interannual variability in the physics and biology of shelf seas.
In discussion, the present limitations of S2P3-R are emphasised, and future
developments are outlined. |
