Assessment of the sensitivity of the RegCM5 model to physical parameterization schemes in precipitation simulation in the Bandama watershed (Côte d’Ivoire)

Sensitivity of WRF Rainfall Simulations to Physical Parameterization Schemes over Tropical Peatlands in the Maritime Continent

Orographic Quantitative Precipitation Forecast Sensitivity to the Choice of Microphysics Parameterization during a U.S.West Coast Atmospheric River Event

The Center for Western Weather and Water Extremes provides high-resolution forecasts of Atmospheric Rivers (ARs) along the U.S. West Coast. Using a 34-year reforecast dataset, we assess the sensitivity of orographic quantitative precipitation forecasts (QPF) associated with ARs to bulk microphysics parameterization (...

A Multi-Model, Multi-Scheme Evaluation of Scale-Aware Convective Parameterization for Gray-Zone Tropical Cyclone Simulation over the South China Sea

Gray-zone tropical cyclone (TC) simulations, in which convection is partially resolved and partially parameterized at grid spacings of approximately 3 to 15 km, are sensitive to how grid spacing changes across adaptive meshes. This study evaluates three scale-aware convective parameterization schemes (CPS), the Grell...

Insights into WRF-Chem Sensitivity in a Coastal Region of Morocco: Chemical Mechanisms, Nesting Options, and Physical Parameterization

The performance of the Weather Research and Forecasting model coupled with chemistry (WRF-Chem) depends on the accuracy of input data and parameterisation schemes. This study examined the sensitivity of WRF-Chem version 4.4.2 to various domain configurations, chemical mechanisms, and physics parameterizations. The mode...

Comparative Performance of Calibrated 2D HEC-RAS and SMS-TUFLOW Classic Models: Effects of Mesh Resolution on Inundation Extent and Water Depth Under Multiple Flood Scenarios

Mesh resolution is a central source of numerical uncertainty in two-dimensional flood modelling because it controls terrain representation, wetting–drying transitions, computational cost, and the transferability of calibrated parameters. Yet controlled evidence remains limited on whether two widely used solvers exhibit...

Evaluation of Riming in the P3‐2ice Microphysics Scheme: A Case Study of Cold‐Air Outbreak Snowfall in Eastern China

Using the multi‐frequency radar suite, ground‐based observations, and the Weather Research and Forecasting (WRF) model with the Predicted Particle Properties microphysics scheme with the version of two‐ice category (P3‐2ice), we study the characteristics of a cold‐air outbreak (CAO) snowfall event on 6–7 December 2024....
