@mainchow10 Yeah, though it is the same app (GR2Analyst) that they show frequently on TWC, I'm using my own color tables that I created specifically for use with tropical systems, so my loops will typically look a bit different. Glad you liked the clip.
Alex had some excellent structure for a Cat 2 hurricane. For a bit before landfall, it had dual rotation centers like Andrew did at its strongest (as I saw from your Andrew loop video). i think this storm would have become a Cat 3 if it stayed out over water for a while longer.
@liquidstl Hi Chris! Yeah... the structure and minimum pressure of Alex were that of a much stronger system than supported by the maximum sustained winds. It looked like it was really trying to pull together fast, right at the end... a few more hours and I'm sure the winds would have caught up to how deep the storm was.
Thanks ... And whats also very interesting is the small "cell" developing right smack in the middle of the eye prior to landfall and how it gets "centrifuged" outward

@cdcollura Thanks, Chris! Yeah the development of a "hub" cloud at the center of the eye is a feature that still isn't understood well. I've read a few papers detailing theories as to why it forms, mostly related to the distribution of the warmest temperatures and associated subsidence within the eye, which in these cases may actually be concentrated in a ring (also referred to as an inner-moat) along the edge of the eye, rather than in the center of the vortex.
@vmax135 how about the hub-cloud being related to the moist outflow from the heavy precipitation in the inner eye wall lifting air converging at the center and colliding with the subsiding air at the center of the eye. Makes decent sense and explains why it is dissipates as heavier precipitation shifts to the left eye wall and falls out of balance.
@DarkStar1O9 It's certainly possible that there's some complex interaction between eyewall convection and eye subsidence that is part of the process for hub cloud formation. Regardless of the mechanism it seems logical that, at the time the hub cloud is present, the greatest subsidence and warming is restricted to a ring along the inner edge of the eye, rather than at the typical location in the center. I've linked a paper that goes into much more detail in this video's description.

The radar on TWC was much lighter than this. Great video though.
