| Abstract: | Three-dimensional large eddy simulation is used to solve the problem for a homogeneous forest canopy. The development of the
Kelvin-Helmholtz instability above the canopy leads to the formation of coherent structures in the atmosphere flow, which
are reproduced in the calculations. The statistical characteristics of the flow obtained from the numerical modeling are compared
with experimental data. The passive admixture transfer from the canopy to the clean atmosphere is studied for two cases, namely,
for constant and variable coupled concentration of the impurity in the canopy. |
