Geometrical Finite-Difference Construction of a Drift Current Spiral with Arbitrary Changing Viscosity

D. E. Besedin and V. L. Lebedev

Considered is a geometrical way of a computer-aid construction of a drift current spiral that can take into account an arbitrary change with depth of the viscosity coefficient introduced in tabular form or as formulas. A new model is simple and can be used in numerical experiment to clarify the impact of different stratification types and special dynamic conditions, for example, waves, on the character of a spiral. The model is not supposed to substitute other models, but can make their selection wider.
