- Low precipitation supercell with a nub shaped lowering on its base
- W902102S
- A closer look at the base of the low-precipitation supercell in W902027S about a half hour later shows that it resembles a stack of plates spinning like a top. The base tapers down to a nub, the “lowering” centered under it. Everything tilts away in the view because of increasing winds with height (vertical wind shear). The disk base was rotating rapidly, about 100mph or 160kph around its edge.
