From: Wind risk assessment of urban street trees based on wind-induced fragility

Figure 8. Model validation results. H: tree height; C_reg: regression coefficient; P_f: failure probability; U₁₀: mean wind speed in 10 min at height of 10 m. (A) Coniferous tree, H = 20 feet (6.1 m), Wind risk assessment of urban street trees based on wind-induced fragility = 130; (B) Deciduous tree, H = 20 feet (6.1 m), = 160; (C) Coniferous tree, H = 35 feet (10.7 m), = 120; (D) Deciduous tree, H = 35 feet (10.7 m), = 180; (E) Coniferous tree, H = 50 feet (15.2 m), = 145; (F) Deciduous tree, H = 50 feet (15.2 m), Wind risk assessment of urban street trees based on wind-induced fragility = 180; (G) Coniferous tree, H = 70 feet (21.3 m), = 165; (H) Deciduous tree , H = 70 feet (21.3 m), = 180.
