Quasi‐quadrennial variability in European precipitation
Abstract The variability of seasonal precipitation anomalies over Europe displays significant spectral peaks at quasi‐quadrennial periods, appearing in power spectra of the two leading principal components of the field. Band‐pass filtering of these time series reveals the presence of two different s...
