The contour advection method is one of the Lagrangian approaches to the simulation of scalar field transport processed in quasi-two-dimensional inviscid incompressible flows considered in numerous applications of geophysical hydrodynamics. In order to conserve the computational efficiency when the tracer field structures become very complex, this method includes a contour editing procedure. This paper analyzes the basic steps of this procedure and proposes an accelerated topology change algorithm to substantially reduce computing cost.
