AI Article Synopsis
- The study focused on micrometeorological data from a Korean pine forest in Changbai Mountain in 2003, using a second-order closure model to analyze turbulence.
- The model's calculated mean wind profile matched the actual measurements, indicating accurate modeling of wind behavior.
- Significant findings included reduced Reynolds stress within the forest, with maximum turbulence and wind shear occurring at the forest-atmosphere interface, while most turbulence deeper in the canopy was influenced by conditions above it.
Article Abstract
Based on the micrometeorological data of broad-leaved Korean pine forest in Changbai Mountain in 2003, a second-order closure model was employed to calculate and analyze the turbulent characteristics within and above the canopy of the forest. The calculated mean wind profile was coincident with the measured one. The Reynolds stress within the forest was significantly attenuated. The turbulent strength, velocity flux, and skew were the largest at forest-atmosphere interface, as well the wind shear. With the increase of velocity skew, the turbulent intermittence became more significant, and the downward turbulent eddy within the canopy was limited. Most of the turbulent deeply within the forest canopy was produced by the non-local contributions above the canopy.
