Multifractal analysis of rainfall in Barcelona

What is it about?

Fractal analysis techniques were applied to extreme rainfall episodes registered in the metropolitan area of Barcelona, as well as to a selection of them which can be considered synoptic events. The multifractal parameters obtained were significantly different probably showing the influence of the rain generation mechanisms involved in each case. This influence were revealed also in the analysis of the effects of seasonality on the multifractal behavior of rainfall in Barcelona.

Why is it important?

In most of the studies on scale properties in the rainfall process, multifractal behavior has been investigated without taking into account the different rain generation mechanisms involved. However, it is known that rain processes are related to certain scales, determined by climatological characteristics as well as regional and local meteorological features. One of the implications derived from this study is the possibility that the rainfall multifractal parameters could depend on the generation mechanism of the dominant precipitation.
