A bit of nomenclatural clarity: The phenomenon that Mollison in the
Designer's Manual calls an Ekman spiral, the spiraling of wind when it
hits a barrier, is not an Ekman spiral. I have not been able to find a
name for that effect.
Nice patterns, Loren. Ripples, some shear from two moving air masses,
and some kind of swirling wake that's on its way toward being a von
Karman vortex street.
