Comparing different numerical treatments of advection terms for wind-indued circulations in Lake Constance.

Abstract

Three difference methods - a high-resolution total variation diminishing (TVD) method and two traditional central and upstream di®erence schemes (CDS and UDS) - are used for the numerical treatment of advection terms in the simulations of lake circulation. Results are compared for wind-induced motions in Lake Constance for both homogeneous and stratified cases. It is demonstrated that the traditional numerical treatments of advection terms are rather questionable, although they are most frequently employed in almost all ocean/lake circulation models, whereas the TVD technique yields the most reasonable results.
