Table 1: Frequencies , periods , maximum power  , significance levels p, and latitudes  (where power exceeds the given significance level) for the labeled regions in Figs. 3a and 3b, respectively. The error is half the frequency resolution. The time intervals (last column) were determined using the  significance contours of Morlet wavelets with nondimensional frequency 6 or 9 (cf. Sect. 2.2). A time interval in an otherwise empty row belongs to the periodicity above. Rows in brackets indicate periodicities that are evident in the wavelet power spectra (with 99.9% significance) but not in Figs. 3a and 3b. The frequencies for  and  were computed with a five times higher frequency resolution. The original values calculated with the standard frequency resolution are () and ( ).
