Abstract
The Nimes-Courbessac (1949-1992) 12 hrs. resolution rainfall database exhibits a multifractal behaviour for periods of time of at least 12 h rs. to about 16 days. Using the Double Trace Moment data analysis tech nique, we estimated the basic multifractal indices alpha almost-equal- to 0.45+/-0.05 and C1 almost-equal-to 0.60+/-0.02, which characterize the process in the framework of universal multifractals. The probabili ty distribution of large fluctuations has a hyperbolic fall-off.
