Test particle transport in two dimensional turbulence over spatial scales much longer than the correlation length has been studied numerically, addressing the dependence of the diffusion features on a convenient dimensionless parameter, the Kubo number. A scaling argument is introduced to discuss the difference between the numerical results and the predictions of current analytic theories.
