North Atlantic oscillation (NAO) and precipitation in Galicia (Spain)

摘要

In this study we investigate the time-scale at which NAO and ENSO are associated with the precipitation in Galicia (Northwestern of Spain), looking for possible climate-predictors. The existence of preferred frequencies in all series was analyzed by using SSA (Singular Spectral Analysis), whereas the statistical significance of the results was checked by using the Monte-Carlo method. Results suggest that NAO and precipitation in Galicia could be related at a time scale of 8 years whereas the influence of ENSO is not significant.
