The Ekman theory has major conseque

The Ekman theory has major consequences
for wind-driven ocean circulation. Thus it is
important to confirm and refine Ekman’s theory
with ocean observations. Observations of
Ekman response are difficult because of the
time dependence of the wind. California
Current observations produced an easily visible
Ekman-like response because the wind direction
was relatively steady (Figure 7.7 and
Chereskin, 1995).
