Horizontal radar slices through Hurricane Erin,
showing how the circulation of the storm weakens with increasing height
above the ground (the altitude of each radar slice is shown on the left
side of the figure). It is the weakening circulation with increasing
altitude that causes the "stadium effect" in the eye-structure of
hurricanes. The perfectly circular area of black to the right of the
eye is associated with the radar's inability to see precipitation in
that region and is not related to the "stadium effect" (courtesy of
NOAA).
