THE STRUCTURE OF TURBULENCE NEAR A TALL FOREST EDGE: THE BACKWARD-FACING STEP FLOW ANALOGY REVISITED.

The article discusses a study about the backward-facing step flow analogy of the structure of turbulence in a tall forest edge. This paper focuses on the flow disturbances near tall forest edges which are investigated by scholars in ecology, forest management, meteorology and fluid mechanics. The authors argue that the existing framework of forest canopy turbulence structure does not go in general with dense forested edges. They point out that the flow have several attributes in backward-facing step (BFS) flow. Analogies are presented in terms of rotor-like circulations.
