To accurately predict the long-term wind-induced snowdrift on building roofs, this study developed a modified numerical model within the multistage quasi-steady simulation method. A novel method was introduced to estimate prototype blowing snow duration based on wind tunnel experimental data, and a boundary mesh adaptive technique combined with the bounded radial basis function interpolation method was implemented to track dynamic boundary changes during snow drifting. Additionally, the influence of temporal parameters, including blowing snow duration, time allocation schemes, and number of st...
