Abstract
The effect of spatially correlated noise on Turing structures is analyzed b oth experimentally and numerically. Using the photosensitive character of t he chlorine dioxide-iodine-malonic acid reaction-diffusion system, spatial randomness is introduced in the system. In the presence of noise, Turing pa tterns appear and are stable at levels of average illumination that would b e more than sufficient to suppress pattern formation in the case of homogen eous illumination.
