This image was simulated using a 3-D acoustic
model that accounts for wind-induced refraction.
It is a single vertical mode at 2mHz. Acoustic
energy propagating from the impact site gets
pinched by refraction into intense streaks.
The pinching is most significant for energy
that propagates nearly parallel to lines of
latitude because the wind component of the
wave speed is greatest. Since this behavior is
geometric, it occurs at all frequencies. It
therefore seems likely that features like this
should show up in IR data. Has anyone seen
anything like this yet?
