Complete synchronization of convective patterns between Gray-Scott systems

Two identical 1D autocatalytic systems with Gray–Scott kinetics–driven towards convectively unstable regimes and submitted to independent spatiotemporal Gaussian white noises–are coupled unidirectionally, but otherwise linearly. Numerical simulation then reveals that (even when perturbed by noise) the slave system replicates the convective patterns arising in the master one to a very high degree of precision, as indicated by several measures of synchronization.
