Table 2: Frequencies , periods , maximum power  , significance levels p, and latitudes  (where the power exceeds the given significance level) for the labeled regions in Figs. 5a and 5b. Asterisks indicate that the  level was also reached. The error is half the frequency resolution. The time intervals (last column) were determined using the  significance contours of Morlet wavelets with nondimensional frequency 12 (cf. Sect. 2.2). The time interval for the peak at in region  could not be determined unambiguously.
