The trends of four common climate change indices related to extreme precipitation events during the typhoon season (July–October) from 21 stations in Taiwan are investigated using a robust nonparametric method. Upward trends in precipitation intensity and 5‐day total precipitation amounts prevail from 1950 to 2010. Longer drought duration is also noted, in southern Taiwan in particular. Daily precipitation during the typhoon season is further partitioned into typhoon and monsoon rainfall. Precipitation intensity induced by typhoons and monsoon systems has both increased over the last 60 years; these two components collectively contribute to strong upward trend in precipitation intensity.
