Abstract
Front dynamics modeled by a reaction-diffusion equation are studied under t he influence of spatiotemporal structured noises. An effective deterministi c model is analytical derived where the noise parameters, intensity, correl ation time, and correlation length appear explicitly. The different effects of these parameters are discussed for the Ginzburg-Landau and Schlogl mode ls. We obtain an analytical expression for the front velocity as a function of the noise parameters. Numerical simulation results are in a good agreem ent with the theoretical predictions.
