The evaluation of possible climate change consequence on extreme rainfall hassignificant implications for the design of engineering structure andsocioeconomic resources development. While many studies have assessed theimpact of climate change on design rainfall using global and regional climatemodel (RCM) predictions, to date, there has been no comprehensive comparison orevaluation of intensity-duration-frequency (IDF) statistics at regional scale,considering both stationary versus nonstationary models for the future climate.To understand how extreme precipitation may respond to future IDF curves, weused an ensemble of three RCMs participating in the North-American (NA)-CORDEXdomain over eight rainfall stations across Southern Ontario, one of the mostdensely populated and major economic region in Canada. The IDF relationshipsare derived from multi-model RCM simulations and compared with thestation-based observations. We modeled precipitation extremes, at differentdurations using extreme value distributions considering parameters that areeither stationary or nonstationary, as a linear function of time. Our resultsshowed that extreme precipitation intensity driven by future climate forcingshows a significant increase in intensity for 10-year events in 2050s(2030-2070) relative to 1970-2010 baseline period across most of the locations.However, for longer return periods, an opposite trend is noted. Surprisingly,in term of design storms, no significant differences were found when comparingstationary and nonstationary IDF estimation methods for the future (2050s) forthe larger return periods. The findings, which are specific to regionalprecipitation extremes, suggest no immediate reason for alarm, but the need forprogressive updating of the design standards in light of global warming.
