The presence of very-large-scale motions in wall-bounded turbulent flows is commonly
associated with their footprint in the form of the superposition of the large scales at the wall …

Triadic scale interactions in a turbulent boundary layer

S Duvvuri, BJ McKeon - Journal of Fluid Mechanics, 2015 - cambridge.org
A formal relationship between the skewness and the correlation coefficient of large and
