The Response of Daily and Sub‐Daily Extreme Precipitations to Changes in Surface and Dew‐Point Temperatures

Extreme precipitation events are expected to increase in frequency and intensity the future climate, but magnitude of these changes remains uncertain. The relationship between extreme surface temperature has been investigated more robustly assess projected increases considering that is adequately simulated. Relationships (daily sub-daily) air (SAT) or dew-point (SDPT) analyzed this study using 50-members ensemble from fifth version Canadian Regional Climate Model covering Northeastern North America region over period 1956–2099. Temperature-precipitation scaling rates (TPSRs) were estimated local SAT SDPT seasonal anomalies as covariate both periods for 2–100-year durations ranging 1 24 h. Contrasting responses obtained when SDPT, especially southern part domain. Median entire domain close Clausius-Clapeyron (°C) while they much smaller even negative regions, showing moisture availability a key factor regions. TPSR based on also constrained can be used estimate short-duration historical large
