Logarithmic profiles of velocity in stably stratified atmospheric boundary layers
Yu Cheng, Andrey Grachev, Chiel van Heerwaarden
The universal velocity log law first proposed by von Kármán in the near-wall region of turbulent shear flows is one of the cornerstones of turbulence theory. When buoyancy effects…

On the Power-law Scaling of Turbulence Cospectra Part 1: Stably Stratified Atmospheric Boundary Layer
Yu Cheng, Qi Li, Andrey Grachev +3
Turbulent fluxes in the atmospheric surface layer are key input for the prediction of weather, hydrology, and carbon dioxide concentration. In numerical modelling of turbulent flux…
