On local isotropy and scale dependence of pair dispersion in turbulent canopy flows
Ron Shnapp, Alex Liberzon, Yardena Bohbot-Raviv +1
Canopy flows in the atmospheric surface layer play important economic and ecological roles, governing the dispersion of passive scalars in the environment. The interaction of high-…
