- •
Wall flow is an important mechanism in the creation of urban wind flows.
- •
Natural convective wall flow was measured for the largest Rayleigh number so far.
- •
The outer layer was governed by the law of the plumes with Gaussian profile.
- •
The natural convective flow exhibits a diurnal profile.
- •
Our new data support the plume theory of the natural convection at high Ra number.
