摘要：

Recent studies have shown that the trajectories of drogued drifters on the ocean surface have a fractal. structure which may be described by fractional Brownian motion. A method is detailed which allows the generation of fractional Brownian motions within a two dimensional particle tracking ocean surface dispersion model. This technique enables the modeller to more accurately mimic particle paths, enhancing the prediction of diffusion and dispersion.
