AbstractThe historical records of temperature and rainfall at Ebre Observatory (40.8º N, 0.5º E) and the relative sunspot numbers have been used to study the possible influence of the 11-year solar cycle over the meteorological parameters. Spectral and cross-correlation analysis have been applied in order to find such a relationship. The yearly average maximum temperature displays a period near 11 years, while the yearly averaged minimum temperature and yearly rainfall values do not present any significant peak about that period. It has been obtained that the 11-year solar cycle and the 11-year oscillation found in the maximum temperature are coherent, practically in phase. Moreover, an 11-year oscillation is found to be significant in the cross-correlation between the solar activity data and the maximum temperature. The results show a possible relation of the 11-year solar activity cycle on the maximum temperature data used here.
