Researchers Highlight Role of Wind Flow in Urban Heat Mitigation

Experts note that near-surface wind speeds have declined globally since the 1980s due to dense urban infrastructure, high-rise buildings, and reduced vegetation.

Obstructions from tall buildings and boundary walls create sheltered pockets and trap heat, compounding urban heat island effects during high humidity.

Urban planning approaches can utilize aerodynamic principles like the Venturi and downdraught effects to maintain pedestrian-level wind corridors and improve urban cooling.
