Abstract. The WRF-Chem model coupled with a single-layer urban canopy (UCM) is integrated for 5 years at convection-permitting scale to investigate the individual and combined impacts of urbanization-induced changes in land cover pollutant emissions on regional climate Yangtze River Delta (YRD) region eastern China. Simulations urbanization effects reasonably reproduced observed features temperature precipitation YRD region. Urbanization over induces an heat island (UHI) effect, which...
Abstract. A state-of-the-art regional model, the Weather Research and Forecasting (WRF) model (Skamarock et al., 2008) coupled with a chemistry component (Chem) (Grell 2005), is snow, ice, aerosol radiative (SNICAR) that includes most sophisticated representation of snow metamorphism processes available for climate study. The used to simulate black carbon (BC) dust concentrations their forcing in seasonal over North China January–February 2010, extensive field measurements evaluate...

Abstract. In this study, we investigated the sensitivity of net radiative fluxes (FNET) at top atmosphere (TOA) to 16 selected uncertain parameters mainly related cloud microphysics and aerosol schemes in Community Atmosphere Model version 5 (CAM5). We adopted a quasi-Monte Carlo (QMC) sampling approach effectively explore high-dimensional parameter space. The output response variables (e.g., FNET) are simulated using CAM5 for each set, then evaluated generalized linear model analysis....
Abstract. This paper explores the feasibility of an experimentation strategy for investigating sensitivities in fast components atmospheric general circulation models. The basic idea is to replace traditional serial-in-time long-term climate integrations by representative ensembles shorter simulations. key advantage proposed method lies its efficiency: since fewer days simulation are needed, computational cost less, and because individual realizations independent can be integrated...

Herein, we show effects dominant factors dynamic source on modeling multiple aspects. We found that in Asia 2001–2020 demonstrates pronounced monthly annual variability, showing wider distribution March than July lower probability uplifting summer spring. The functions Gobi Desert...

Reasonably modeling the magnitude, south–north gradient and seasonal propagation of precipitation associated with East Asian summer monsoon (EASM) is a challenging task in climate community. In this study we calibrate five key parameters Kain–Fritsch convection scheme WRF model using an efficient importance-sampling algorithm to improve EASM simulation. We also examine impacts improved on other physical process. Our results suggest similar sensitivity values optimized across years different...
