🌪️ Kinetic Destructive Energy & Wind Load Ratio
Aerodynamic wind loading scales quadratically with velocity (P = 0.5 * ρ * v²). Storm A exerts approximately 0.42x of the peak structural dynamic wind pressure of Storm B.
Formula: Dynamic Pressure q = 0.5 · ρ · V²
Ratio (Dujuan / Krovanh) = (54² / 83²) = 0.42
Ratio (Dujuan / Krovanh) = (54² / 83²) = 0.42
🌊 Inverse Barometer Sea Surface Rise Potential
A hydrostatic approximation (1 cm sea surface rise per 1 hPa atmospheric pressure drop below ambient 1013 hPa).
Hydrostatic Sea Rise: Δh ≈ (1013 - P_min) × 1 cm
