Abstract: We study Lyapunov vectors LVs corresponding to the largest Lyapunovexponents in systems with spatiotemporal chaos. We focus on characteristic LVsand compare the results with backward LVs obtained via successive Gram-Schmidtorthonormalizations. Systems of a very different nature such as coupled-maplattices and the continuous-time Lorenz `96 model exhibit the same featuresin quantitative and qualitative terms. Additionally we propose a minimalstochastic model that reproduces the results for chaotic systems. Our worksupports the claims about universality of our earlier results I. G. Szendro etal., Phys. Rev. E 76, 025202R 2007 for a specific coupled-map lattice.
