Annual North Sea simulation

Here the annual simulation of the Northern Sea at 5920" N and 117' E during the year 1998 as discussed by Bolding et al. (2002) is performed.

For this simulation, time series of surface slopes
and
were extrapolated from observations
during autumn 1998 based on four partial tides by means of harmonic analysis
(the program for doing this was kindly provided by Frank Janssen, now at
the Baltic Sea Research Institute Warnemünde).
All necessary meteorological data are from the UK Meteorological Office Model.
For calculating the resulting surface fluxes, the bulk formulae from
Kondo (1975) are used here.
Since no observations for the sea surface temperature (SST)
are available for the whole year 1998 at station NNS, the simulated SST
is used as input into the bulk formulae.
For the evolution of the vertical
salinity profile, which is known to stabilise stratification
during summer months, a relaxation to results obtained with a
prognostic three-dimensional model of the North Sea
by Pohlmann (1996).
By doing so, the horizontal advection, which is the dominant process
for salinity dynamics in the Northern North Sea, is parameterised.
