Multipoint Monin–Obukhov Similarity and Its Application to Turbulence Spectra in the Convective Atmospheric Surface Layer

Autor: Chenning Tong, Khuong X. Nguyen

Publikováno v: Journal of the Atmospheric Sciences. 72:4337-4348

A generalized Monin–Obukhov similarity hypothesis for the atmospheric surface layer is proposed. It employs the Monin–Obukhov length as a length scale in both the horizontal and vertical directions, in contrast to the original Monin–Obukhov sim

Investigation of subgrid-scale physics in the convective atmospheric surface layer using the budgets of the conditional mean subgrid-scale stress and temperature flux

Autor: Khuong X. Nguyen, Chenning Tong

Publikováno v: Journal of Fluid Mechanics. 772:295-329

The subgrid-scale (SGS) physics in the convective atmospheric surface layer is studied using the SGS stress and SGS scalar flux. We derive the budget equations for the conditional mean SGS stress and SGS temperature flux and show that, for transport-

Measurements of the budgets of the subgrid-scale stress and temperature flux in a convective atmospheric surface layer

Autor: Chenning Tong, Steven P. Oncley, Thomas W. Horst, Khuong X. Nguyen

Publikováno v: Journal of Fluid Mechanics. 729:388-422

The dynamics of the subgrid-scale (SGS) stress and scalar flux in the convective atmospheric surface layer are studied through the budgets of the SGS turbulence kinetic energy (TKE), the SGS stress and the SGS temperature flux using field measurement
