Assessments of future climate extremes in China by using high-resolution PRECIS 2.0 simulations

Based on bias-corrected future projections from the Providing REgional Climates for Impacts Studies (PRECIS) regional climate model under both RCP4.5 and 8.5 scenarios over China, extreme climatic events at middle end of twenty-first century are investigated in this paper. The performance PRECIS is validated using comparisons with observations HadGEM2-ES projections, bias correction adds fidelity to basic variables events. In future, our single-realisation estimates show that number frost days projected decrease tropical nights increase. Including northeast Sichuan Basin, lower reaches Yangtze River south consecutive dry will increase estimates, which exhibit a spatial distribution almost similar wet coming decades. Although precipitation indices associated duration increase, simple index depicting intensity east China projections. Daily rainfall above 50 mm, usually regarded as rainstorm event, predicted scenario most estimates; while same change pattern occur southernmost similarly spatially distributed RCP8.5 scenario, first then slow region. conclusion, indicate persistence time, but not significant future. comparison those shows be enhanced higher emissions scenario; hence, reductions greenhouse gas help alleviate effects
