Response of equatorial Pacific upper ocean current to westerly wind bursts
摘要
Abstract
The characteristics of the response of equatorial Pacific upper ocean current to westerly wind bursts (WWB) were analyzed in the frequency domain by using wind and ADCP data collected bythe Shiyan 3 during TOGA-COARE IOP
1992–1993. The preliminary results showed that the response consisted of an eastward surface jet at shallower than 60m depth
a westward counter current centering near 100m and a shear layer between them
with the variations of all three being nonlinear and nearly synchronous. The oceanic responses in the frequency domain were characterized by occurrences of a remotely forced mixed Rossby-gravity wave with period of 8–10 days in the surface jet and countercurrent at shallower than 110m depth
and two locally forced waves with periods of 24 days and 4–5 days limited in shallower than 70m depth. These fluctuations of the responses depended much more on zonal wind than meridional wind. The results also revealed that the oceanic response to WWB resulted from momentum transport and energy propagation associated with wave
baroclinic mode
nonlinear shear instability
and possibly other factors.
