Microclimate Physics Insights

Concrete superstructure decks act as atmospheric deflectors. The overhang ratio creates a rain shadow zone behind and beneath the girder line, deflecting angled wind-driven precipitation away from embankment bases.

Microclimate Zone: Protected Ground Envelope
Structural Safety Index: Optimal Shelter
Wind velocity attenuation under the superstructure creates a stagnant boundary layer preventing thermal radiation loss.

Structural Microclimate Finding: Under the configured geometry (Overhang: 3.5m, Height: 8.0m, Abutment: 65°), the underside of the girder bridge produces an effective wind shear blockage and driver deflection angle. This confirms why infrastructure superstructures provide robust physical shelter during severe wind and driven rain events.
