Can higher Hoelder exponents of an active tracer field be evaluated — •H. Lustfeld¹ and Z. Neufeld² — ¹Forschungszentrum Jülich, IFF, 52425 Jülich — ²Department of Applied Mathematics and Theoretical Physics, University of Cambridge, Silver Street, Cambridge CB3 9EW, United Kingdom

Concentrations of chemically active tracers, e.g. pollutants in the atmosphere, may have a complex spatial structure. It has been shown that such a structure can be characterized by a Hoelder exponent[1]. We show here that for a complete characterization a set of Hoelder exponents is needed. We compare our results with data from various models.
