Intrinsic randomness, also known as spontaneous stochasticity, has been suggested to limit the finite-time predictability of multiscale chaotic dynamics, but an explicit demonstration of its effect is still lacking. Here, the authors use numerical simulations to show the existence of spontaneous stochasticity in the discontinuous shear layer leading to the Kelvin-Helmholtz instability.
