Abstract: The dynamic effects of small topography (in the sense of the characteristic height of the topography as compared with the vertical thickness of the system of motion) and the Ekman pumping caused by the frictional convergence in the boundary layer on the motion of a typhoon have been qualitatively discussed in this part based on the governing equation of typhoon motion derived in part I of this paper. The results show that a topographical ridge tends to attract the typhoon approaching it and this explains at least partially the phenomenon that the typhoons over the western Pacific tend to accelerate just before their making landfall over the coastal areas.It is also shown that the Ekman pumping at the top of the boundary layer favors the typhoon acceleration along the local steering current.
