摘要: Publisher Summary The interaction between air flow and exchange processes in the canopy is currently being re-examined. This has been prompted by a general disillusionment with classical technique for evaluating heat mass transfer from micrometeorological profiles (the one-dimensional flux-gradient approach). Not only inapplicable to non-homogeneous vegetation uneven terrains, but complete failure yield correct results demonstrated forests (where seems against temperature gradient) model stands wind tunnel. More recently, instruments very rapid response time enable be measured using eddy-correlation, furnish turbulence statistics of u , v w components at different places canopy. Many problems involving are more amenable analysis theory, which rests on dispersal materials parcels rather than quasi-diffusion one dimension. behavior propagules air, mechanical excitation tall plants, optimal design shelter all examples such problems.
