Resumen

The temporal concentration of precipitation may be characterised using several methods. For climatescale precipitation, concentration measures are usually performed by means of dimensionless indices related with the Lorenz curve (Shaw and Wheeler, 1994, Martin-Vide, 2004). Other disciplines employ information entropy formulae such as the Theil Index (TI), derived from the Shannon Index (Cowell, 2000; Jost, 2006).
