Abstract Share this page

Historical daily rainfall events, measured at different Italian stations, are found to follow fractal relationships within specific time ranges. It is found that the fractal dimension D describes the strength of the clustering of daily rainfall events in a more realistic way than the commonly used number of daily rainfall events: the more isolated the clusters, the smaller the value of D. The large dependence of D and of the specific scaling region on the threshold intensity is an indication of a more complex property of the rainfall called multifractality: a large-scale rain-field is successively broken into smaller and smaller eddies, each receiving an amount of the total field specified by a multiplicative parameter. Circumstantial evidence indicates, moreover, that the significant secular decreases of D over the Mediterranean area can be reasonably related to the simultaneous coherent decrease of zonal atmospheric circulation.
