title: Effect of colored noises on spatiotemporal chaos in the complex Ginzburg-Landau equation.
abstract: The effect of colored noises, which are correlated both in space and time, on spatiotemporal chaos in the complex Ginzburg-Landau equation has been studied numerically. The correlations of spatiotemporal patterns as a function of characteristics of noise were calculated. We found that there exists an optimal correlation length of noise where the system establishes its maximal spatial correlation; a small temporal correlation of noise corresponds to a larger correlation length in the system; and that an increase of noise intensity enhances the spatial correlation of the spatiotemporal patterns. Besides, the frequency of temporal correlation function, which is a complicated oscillation, also depends on properties of the noise.
