Abstract:
Abstract. We present Nemo-Nordic, a Baltic and
North Sea model based on the NEMO ocean engine. Surrounded by highly industrialized
countries, the Baltic and North seas and their assets associated with
shipping, fishing and tourism are vulnerable to anthropogenic pressure and
climate change. Ocean models providing reliable forecasts and enabling
climatic studies are important tools for the shipping infrastructure and to
get a better understanding of the effects of climate change on the marine
ecosystems. Nemo-Nordic is intended to be a tool for both short-term and
long-term simulations and to be used for ocean forecasting as well as process
and climatic studies. Here, the scientific and technical choices within
Nemo-Nordic are introduced, and the reasons behind the design of the model
and its domain and the inclusion of the two seas are explained. The model's
ability to represent barotropic and baroclinic dynamics, as well as the
vertical structure of the water column, is presented. Biases are shown and
discussed. The short-term capabilities of the model are presented, especially
its capabilities to represent sea level on an hourly timescale with a high
degree of accuracy. We also show that the model can represent longer
timescales, with a focus on the major Baltic inflows and the variability in
deep-water salinity in the Baltic Sea.
