Analysis of indicators for evaluating the wind environment in a modified communityTo assess the effectiveness of the design under varying wind velocities in the study area, the standard deviation of the prevailing wind velocity in May was calculated as σ = 3.17. Comparative analyses of the design performance were conducted under wind velocity fluctuations of ±0.5σ, ± 1σ, ± 1.5σ, and ±2σ, respectively. The results are shown inTable 15.
