Figure 7.8.
Experimentally measured flow evolution of a dipolar vortex encountering a weak slope topography with angle
α
=3.4
◦
(left panels) and a steeper slope with inclination
α
=6.8
◦
(right panels). Adapted from
van Heijst et al.
[2012]. The snapshots
are taken at
t
= 3 s (top) and
t
= 9 s (bottom). The graphs show the horizontal flow field (vectors) and the
ω
z
vertical vorticity
component (red/blue colors indicate positive/negative values) measured at the free surface. The horizontal black lines indicate
the position of the edge of the slope. For color detail, please see color plate section.
