Abstract. Despite the implementation of Clean Air Action Plan by Chinese government in 2013, issue increasing surface ozone (O3) concentrations remains a significant environmental concern China. In this study, we used an improved regional climate–chemistry–ecology model (RegCM-Chem-YIBs) to investigate impact anthropogenic emissions, meteorological factors, and CO2 changes on summer O3 levels C...

[1] We evaluate the impact of anthropogenic emission inventory and climate model grid resolution on aerosol concentrations and black direct aerosol top of atmosphere forcing. Anthropogenic aerosol concentrations of sulfate, black carbon (BC), and organic carbon (OC) are simulated using a high-resolution (25 km) regional climate model (RegCM) with (1) the 2000 1° 1° EDGAR inventory and (2) the 1...

Abstract The CORDEX Flagship Pilot Study ELVIC (climate Extremes in the Lake VICtoria basin) was recently established to investigate how extreme weather events will evolve this region of world and provide improved information for climate impact community. Here we assess added value convection-permitting scale simulations on representation moist convective systems over around Victoria. With aim,...

Irrigation activities have been recognized as one of the most potentially sustainable land management practices to tackle climate change. In this study, we investigated impacts present-day irrigation on regional temperature extremes changes in China using state-of-the-art model RegCM-4.8.2, through two sets long-term numerical experiments (i.e., with and without irrigation). The key findings ar...

Five regional climate models (RCMs)—CCLM, RegCM, HadGEM3-RA, SNURCM and WRF—participating in the Coordinated Regional Climate Downscaling Experiment-East Asia (CORDEX-EA) Phase 2 project are evaluated for their ability to simulate spatiotemporal variability Asian summer precipitation. For this purpose, two dynamical downscaling sets, experiments forced by ERA-Interim reanalysis data (reproducti...

In order to investigate the climate effects of dusts, a regional model (RegCM 4.6) with dust scheme was used simulate direct radiative forcing and air temperature response at 2 m near surface dusts over eastern Asia. Two sets experiments were conducted, one without aerosols. The experiment covered main occurrence months from March May for 8 years (2011−2018), simulation results evaluated agains...

Abstract Gridded observational datasets are often used for the evaluation of regional climate model (RCM) simulations. However, uncertainty observations affects evaluation. This work introduces a novel method to quantify uncertainties in and how these affect RCM Besides precipitation temperature, our uses geographic variables (e.g. elevation, variability effect station), which considered as sou...

With increasing computational power, the regional climate modeling community is moving to higher resolutions of a few kilometers, named convection-permitting (CP) simulations. This study aims present an assessment precipitation metrics simulated with non-hydrostatic model RegCM-4.7.1 at CP scale for decade-long period (2001–2010) Bulgaria. The simulation 15 km grid spacing uses ERA-Interim (0.7...
