Abstract: n error propagation analysis is conducted to estimate random errors in the friction velocity u* and the Monin?Obukhov similarity theory (MOST) stability variable z/L from estimated random errors in the turbulent fluxes. ...

Abstract: Phenomena such as large-scale shear, buoyancy, and the proximity to the ground surface significantly affect interactions among scales in atmospheric boundary layer turbulent flows. Hence, these phenomena impact parameters ...

Abstract: caling laws for the longitudinal structure function in the atmospheric surface layer (ASL) are studied using dimensional analysis and matched asymptotics. Theoretical predictions show that the logarithmic scaling for the ...

Abstract: numerical study of the effect of entrainment fluxes at the top of the atmospheric boundary layer (ABL) on dissimilarity between scalars within the mixed and surface layers is conducted. Simulation results clearly show that ...

Abstract: Eddy diffusivity models are a common method to parameterize turbulent fluxes in the atmospheric sciences community. However, their inability to handle convective boundary layers leads to the addition of a nondiffusive flux ...

Abstract: heoretical predictions for dispersion of heavy particles above an area source are used to formulate a new framework to interpret measurements of spore concentration above an infected field. Experimental measurements of ...

Abstract: AbstractThe low-wavenumber regime of the spectrum of turbulence commensurate with Townsend?s ?attached? eddies is investigated here for the near-neutral atmospheric surface layer (ASL) and the roughness sublayer (RSL) above ...

Abstract: Observational data from two field campaigns in the Amazon forest were used to study the vertical structure of turbulence above the forest. The analysis was performed using the reduced turbulent kinetic energy (TKE) budget ...
