キーワード：ENSO, Tropical Cyclone, Climate Change

One of ENSO’s most important influences is its worldwide modulation of tropical cyclone (TC) activity. TC is one of the most severe natural disasters to humankind. Because TC attributes (e.g., track, intensity, rainfall, genesis, landfall locations, size, translation speed, rapid intensification, total storm days, and accumulated cyclone energy) can be much controlled by large-scale oceanic and atmospheric conditions, TCs can be substantially altered by ENSO. ENSO can modify TC characteristics via both atmospheric and oceanic pathways. This talk focuses on the ocean aspect. The possible compounded influence from ENSO and global warming to TCs in the western North Pacific (i.e. typhoons) and consequential impact implications will also be discussed.
