The relationship between a decaying strong turbulence and kinetic instabilities in a slowly expanding plasma is investigated using two-dimensional (2D) hybrid expanding box simulations. We impose an initial ambient magnetic field perpendicular to the simulation box, and we start with a spectrum of large-scale, linearly polarized, random-phase Alfvénic fluctuations that have energy equipartition between kinetic and magnetic fluctuations and vanishing correlation between the two fields.

Kinetic dissipation occurs at small scales, but the overall rate is apparently controlled by large scale dynamics, and in the solar wind and corona the protons are typically hotter, suggesting that these natural systems are in the large amplitude turbulence regime.
