Aircraft wake vortices have been modeled using an unsteady, two-dimensional laminar (constant eddy viscosity) approximation of the Navier-Stokes equations, to study the influence of ground coupling, stratification, and crosswind on vortex system behavior and decay. Initialization and boundary conditions are developed and implemented systematically for a nonuniform grid representation of the semi-infinite domain containing a vortex pair. Subsequently, the physics of wake vortex interactions with the ground for different types of surface weather conditions are discussed.
