Figure 2
Wavelet power spectra of velocity and temperature. Wavelet spectra of depth-averaged velocity (a) ud, (b) vd, and (c) temperature obtained using a Morlet wavelet normalized with the corresponding variance. Black contours enclose the regions with a confidence level greater than 95%, red dashed lines indicate the cone of influence, white dashed lines represent the periods of diurnal K1 and semidiurnal M2 tides. Magenta lines indicate periods of 30- and 80-day, and the yellow dashed line in each panel indicates period 50-day.
