This article presents time scaling analysis, indicating the NW Pacific cyclone′s track is a non-scaling system,whose associated variance spectrum follows a law raised to the negative 2nd～3rd power as a function increasing frequency, whichholds for any of the studies tracks.It leads to the predictable time scale of 3～4days for most of the tracks observed in a range of seasons and regions, The anomalous paths are found to be predictable only for l～2days,however.
