Numerical Analysis Seminars: Contour Advection

Presented by David Dritschel (St Andrews),

18 February 2005 14:00 in CM105

"Contour Advection is an outgrowth of the Contour Dynamics method pioneered by Zabusky and colleagues in the late 70's. Both numerical methods track material, conserved tracer fields in fluid flows by following field isolevels (or discontinuities) explicitly --- i.e. by tracking a finite set of points making up each contour. Contour Advection has proven useful in a variety of contexts, most importantly in modelling stratified rotating flows (like the atmosphere and oceans). This talk reviews the essential features of the method, illustrates its use in modelling geophysical turbulence, discusses its convergence properties, and presents some challenges for future research.
