Figure 16.— Spectral plot of 6-h meridionul wind stress (\VS) and adjusted sea 

 level (SL) for the upwelling period (df = 100) at Monterey, Calif. The horizon- 

 tal a\es are frequency in cycles per day (cpd). The upper plot shows spectral 

 density of wind stress (in (dynes/cm-) : cpd) and sea level (in cm- cpd): the mid- 

 dle plot shows the squared coherence of the two series; and the lower plot shows 

 the phase.
