Abstract

A semianalytical method based on a mass conservation principle is presented for describing the transition-layer profiles of mean wind speed and momentum diffusivity and for estimating the aerodynamic characteristics of forest and tall vegetation canopies. This method incorporates density and vertical structure of the canopy and assumes that the transition-layer mean wind speed profile can be expressed in polynomial form having second-order osculation. It is also suggested that canopy structure has a major influence on the transition-layer mean wind speed and momentum diffusivity profile. The proposed methodology may help in simulating airflow for use in large-scale models of plant-atmosphere exchanges. 21 refs., 5 figs.

Estimating the zero-plane displacement and roughness length for tall vegetation and forest canopies using semi-empirical wind profiles

Journal Article Zoumakis, N M - Journal of Applied Meteorology; (United States)

A simple method based on a mass-conservation principle is presented for estimating the aerodynamic characteristics of forest and tall vegetation canopies. The method uses semi-empirical modifications of the profiles in the transition layer, eliminating the need for measured wind data extending into the logarithmic regime. Also, various schemes are presented for determining the transition-layer depth z[sub *] in terms of the particular physical characteristics of the canopy. 10 refs., 3 figs.

Observations of the scale-dependent turbulence and evaluation of the flux-gradient relationship for sensible heat for a closed Douglas-Fir canopy in very weak wind conditions

Journal Article Vickers, D. ; Thomas, C. - Atmospheric Chemistry and Physics Discussions (Online)

Observations of the scale-dependent turbulent fluxes and variances above, within and beneath a tall closed Douglas-Fir canopy in very weak winds are examined. The daytime subcanopy vertical velocity spectra exhibit a double-peak structure with peaks at time scales of 0.8 s and 51.2 s. A double-peak structure is also observed in the daytime subcanopy heat flux cospectra. The daytime momentum flux cospectra inside the canopy and in the subcanopy are characterized by a relatively large cross-wind component, likely due to the extremely light and variable winds, such that the definition of a mean wind direction, and subsequent partitioning of themore »« less

Influence of regional nighttime atmospheric regimes on canopy turbulence and gradients at a closed and open forest in mountain-valley terrain

Journal Article Wharton, S. ; Ma, S. ; Baldocchi, D. D. ; ... - Agricultural and Forest Meteorology

Stable stratification of the nocturnal lower boundary layer inhibits convective turbulence, such that turbulent vertical transfer of ecosystem carbon dioxide (CO ₂), water vapor (H ₂O) and energy is driven by mechanically forced turbulence, either from frictional forces near the ground or top of a plant canopy, or from shear generated aloft. The significance of this last source of turbulence on canopy flow characteristics in a closed and open forest canopy is addressed in this paper. We present micrometeorological observations of the lower boundary layer and canopy air space collected on nearly 200 nights using a combination of atmospheric lasermore »« less

Turbulence within and above regularly arrayed roughness: A wind tunnel study

Conference Roth, M

The main motive for studying turbulent flow in aerodynamically rough environments (urban, forests, crops, etc.) is to understand the processes governing momentum, heat and mass exchange between the flow and the canopy. Apart from this basic interest several practical applications flow which are crucially important in a variety of {open_quote}real world{close_quote} applications: The importance of understanding air flow, microclimates and dispersion of pollutants within the canopy and their coupling to the boundary layer above. Fluid modeling studies have been proved to be useful to overcome some of the observational difficulties encountered in field studies. A wind tunnel study was performedmore »« less
