Taiwan has experienced large increases in extreme rainfall (ER, defined as top 1% by daily total) over the past 60 years. Using 1 km gridded daily rainfall data provided by the Taiwan Climate Change Projection and Adaptation Information Platform (TCCIP), we analyze Taiwan’s rainfall means and trends seasonally and as a function of intensity. ER accounts for about 17% of rainfall in Taiwan, but across much of the island, the 1960-2015 ER trend exceeds the non-extreme rainfall (NR) trend. Most ER occurs during the months of May – October, when warm, southwesterly monsoon flow and frequent typhoons lead to high rainfall totals in southern and eastern regions. In each season, with the possible exception of Mei-Yu Season, ER has increased over most of the island.
