Another view of this vertically oriented rotation is shown with the updraft region in red. If air can enter the storm in the direction of the orange arrow, then there will be rotation in the updraft -- possibly leading to a supercell. Image by COMET. To put this in perspective, we could see how directional wind shear can allow storm inflow air to enter a storm along these vortex rolls.
