| Zusammenfassung |
| QUAGMIRE is a quasi-geostrophic numerical model for performing fast,
high-resolution simulations of multi-layer rotating annulus laboratory
experiments on a desktop personal computer. The model uses a hybrid
finite-difference/spectral approach to numerically integrate the coupled
nonlinear partial differential equations of motion in cylindrical geometry in
each layer. Version 1.3 implements the special case of two fluid layers of
equal resting depths. The flow is forced either by a differentially rotating
lid, or by relaxation to specified streamfunction or potential vorticity
fields, or both. Dissipation is achieved through Ekman layer pumping and
suction at the horizontal boundaries, including the internal interface. The
effects of weak interfacial tension are included, as well as the linear
topographic beta-effect and the quadratic centripetal beta-effect. Stochastic
forcing may optionally be activated, to represent approximately the effects
of random unresolved features. A leapfrog time stepping scheme is used, with
a Robert filter. Flows simulated by the model agree well with those observed
in the corresponding laboratory experiments. |
