This paper presents an examination of the variations of tropical cyclone activity in the western North Pacific Ocean on time scales of a decade or longer. It is shown that the number, intensity, tracks and landfall locations of TCs have substantial variations on time scales from multi-decadal to centennial, together with longer trends. Many of these variations can be explained by similar variations in the atmospheric and/or oceanographic environments in which these TCs are embedded.
