Web5 de nov. de 2024 · Conducting such estimates of the global canyon-induced mixing from observations or modeling studies of single canyons is difficult, as canyons have variations in their shape and size, which may modulate their efficiency in inducing local dissipation. Weband Gratton (1990) suggested that IW can trigger mixing in the SLE, but they also noted that sampling wave-induced mixing is a dif”cult task, owing to the complexity of the bottom topography and the short temporal scale (;min) and spatial scale (;100m)ofIW.
