Van Gogh in his painting could reproduce the turbulence of the clouds. We see several eddies in his painting. A numerical analysis showed it was very realistic as turbulent clouds, as the atmosphere is turbulent.
Eddies move faster when they are bigger, Kolmogorov's Law established. In addition, turbulence is self-similar, meaning many eddies of different sizes are all present at the same time, which is demonstrated in the oil-on-canvas painting.
