4 2.5D Vertical Slice Modelling
Fig. 4.10 Exercise 17: Distributions of the three Eulerian tracer fields after 24 hrs of simulation
enriched bottom water from the stratified side of the front into the frontal zone as
stimulus of biologic production.
4.3.6 Additional Exercises for the Reader
Repeat this exercise with an initial density difference between the top and the bottom
layers of Δρ = 2 kg m
−3 , which is twice that used before, and explore the features
of the resultant tidal mixing front and associated flows.
4.4 Coastal Upwelling
4.4.1 Background
Coastal upwelling is a process by which colder and often nutrient-enriched water is
lifted closer the sea surface where increased light intensity promotes the production
of phytoplankton – a key trigger of the marine food chain.
