Outer-rainband lightning in this type of environment was found to promote axisymmetrization
of convection in the near-core environment, a known precursor to TC intensification.
Although GOES imagery suggested significant axisymmetrization
of the upper-level cloud field during this intensification period, the storm circulation remained highly asymmetric, consistent with the moderate vertical wind shear that continued at this time.
