Abstract

A cyclic behaviour in the summer rainfall dendroclimatic time series (1495-1989) of four weather stations located in the Ebro Valley is studied using the spectral analysis. Once variability associated to high frequency was removed using a three years moving average filter, a 24 year cycle related Hale cycle was identified in three data base. The weather station located in eastern Pyrennees -above 1400 m- does not display coincident significant frequences with that cycle.
