Statistical Analysis of Rainfall Dynamics

Abstract:
In the last few years there have been pieces of evidence that rain events can be considered analogous to other nonequilibrium relaxation processes in Nature such as earthquakes, solar flares and avalanches. In this work we study data from different sites of the world to show that the probability density distribution of rain event size, duration, and their recurrence times (i.e., drought periods) are characterized by a scaling behaviour. The values of the corresponding scaling exponents for the different sites turn out to be very close to each other, suggesting a possible universal behaviour for rain dynamics.
