European dry spell regimes (1951-2000): Clustering process and time trends
(2014-07-01)
Article
Restricted access - publisher's policyAiming to improve the knowledge of droughts in Europe, three indices related to dry spells, DS, regime have been analysed: the number of DS per year, N; the longest annual DS, L-max; and the mean DS length per year, L, for ... -
Extreme normalised residuals of daily temperatures in Catalonia (NE Spain): sampling strategies, return periods and clustering process
(SPRINGER-VERLAG., 2010-06)
Article
Restricted access - publisher's policyExtreme normalised residuals, defined as departures from the average values, of 65 daily maximum, T max, and minimum, T min, temperature series recorded in Catalonia (NE Spain) during 1950–2004 are analysed. Similarly ... -
Fractal analysis and statistics of seismic generation rates: the example of the southern California
