Urban canopy vortex shedding frequency drops unexpectedly during heatwaves—not due to reduced wind speed alone, but because boundary-layer inertial instabilities suppress coherent vortex formation.
Doppler lidar wind profiling reveals Kelvin–Helmholtz billows forming at the top of the urban boundary layer when Δθ/Δz exceeds 8 K per 100 m under low-wind conditions.
