Climate indices such as El Niño-Southern Oscillation in the Pacific Ocean were investigated to find out a relationship between multi-decadal fluctuations of climate change and tropical storms, in particular typhoon in North West Pacific based on the historical record of typhoon-induced disasters. It was found that the ratio of the category.5 typhoon among the all historical typhoon and recorded developed-low pressure systems in the West Pacific was increased in La Niña dominant period. It is foreseeable that attentions on more intensified and frequent tropical storms, typhoon, should be drawn in the forthcoming La Niña dominant period from this study. The similar results were obtained from the historical record of hurricanes in the Atlantic and in the East Pacific Ocean.
