Add to ORKGWe study the evolution of a passive scalar in a two-dimensional flow, highly sheared and stratified in temperature. The simulations are realised with a two-dimensional spectral code without subgrid model. In the physical space, the grid is supplied with 6×2562 squared meshes. The flow is turbulent (Returb ≈ 120) and anisotropic (
