This is more prominent when the angle of contact is large and is named the Marangoni effect [54, 110-112].
Marangoni effect should always be present in clean fluids but is suppressed in water if surfactants are present.

The Marangoni effect and the Rayleigh-Benard effect cover large areas [5-7], included covering slags, contaminant transport, hypermonotectic alloy etc.
As mentioned above, the Marangoni effect and Rayleigh-Benard effect in heat-absorbing tube have been studied extensively, but the influence of the two effects on the interface fluctuation has not been explored thoroughly, due to the high-precision demand for interface tracking.

Professor Geoff Stevens from the University of Melbourne's Department of Chemical and Biomolecular Engineering says while it's possible, he doesn't think Marangoni effects, or the normal diffusion of the chalk or leaf particles from areas of high to low density are involved.
Altshuler and colleagues speculate, the upstream vortex is being reinforced by a Marangoni effect associated with a decrease of the surface tension in the lower reservoir caused by increasing the amount of floating chalk dust or mate leaves.
