Nonlinear systematic analysis is utilized to investigate 180 winter cyclone tracks inmidlatitude Europe(25～60°N,0～90°E)and as many of summer typhcon paths over thewestern Pacific(10～45°N, 110～170°E). Calculation of the associated function of independent cyclone pairs and structural function of the tracks indicates that the fractual dimension is 2～2.5(1.4～1.9) for the cyclone(typhoon) atrack attractor in the continued phase space and the track autosimilarity as well.It follows that the time scale of e-folding growth rate of initial erroris 2 to 3 days,the same being true of regionalized paths. Further,the track time scaling indicatesno scaling feature and the associated variance spectra decrease following the 2～3 power law with increasing frequency.
