Abstract
A Lagrangian method for the numerical simulation of the Kraichnan passive s calar model is discussed. Two different applications are presented. First, the dependence of scalar anomalies on the roughness of the advecting veloci ty field is considered. Second, the anomalous behavior of high order struct ure functions is investigated.
