    Abstract:
    In low-dimensional systems exhibiting chaos the response is temporally random (uncorrelated), but spatially deterministic (correlated). A mechanism has been identified by which the response of a continuum system may be both temporally and spatially uncorrelated, i.e. `turbulent'. The explanation of the mechanism is based upon recent work in chaos of low-to-moderate dimensional systems and also asymptotic modal analysis of high-dimensional systems. The conjectured mechanism and explanation has been confirmed by numerical experiments for a nonlinear system previously studied in the literature
