We study the dynamics of vortices in an inhomogeneous Gross-Pitaevskii equation i∂tu = Δu + 1/ϵ22 ϵ (x) - |u|2). For a unique scaling regime |ρϵ(x) - 1| = O(log ϵ-1), it is shown that vortices can interact both with the background perturbation and with each other. Results for associated parabolic and elliptic problems are discussed.
