We study phase synchronization (PS) of coupled chaotic oscillators as a result of an interplay between local coupling and global noise. In the weak coupling region, noise first significantly enhances spatiotemporal PS, but it spoils the phase coherence of chaotic oscillation and reduces the degree of synchronization at large intensities. The spatiotemporal behavior exhibits coherence resonance. Noise enhanced phase synchronization is of great relevance to ecology.
