Mixing in fully developed incompressible turbulent flows is known to lead toa cascade of discontinuity fronts of passive scalar fields. A one-dimensional(1D) variant of Baker's map is developed, capturing the main mechanismresponsible for the emergence of these discontinuities. For this 1D model,expressions for the height-distribution function of the discontinuity frontsand structure function scaling exponents $\zeta_p$ are derived [for Kolmogorovturbulence, $\zeta_p=\frac 23\log_3(p+1)$]. These analytic findings are in agood agreement with both our 1D simulations, and the results of earliernumerical and experimental studies.
