This is an underwater oxygen ring or more scientifically known as a vortex ring. The phenomenon occurs when a quantity of fluid or gas in a toroid (donut) shape, travels through a medium of fluid or gas, while spinning like a thick circular bracelet that is being rolled off of a person’s arm. | Inverse

The Vortex Ring State (VRS) is a dangerous condition for helicopters, occurring when the rotor descends into its own downwash, creating a turbulent vortex that causes a sudden loss of lift and control. This usually happens during vertical descents or hovering, especially at high descent rates and low airspeeds. Attempts to increase power can worsen the vortex, accelerating descent unexpectedly. To recover, pilots use forward cyclic control to move the rotor out of its downwash and reduce collect

NEW analysis video of the O-ring vortex structure that coincides with the descending bubble of vortex breakdown. This vortex breakdown cycle was evident right from the start of the tornado, with the most intense jet-like vortices happening right beneath the breakdown bubble just before it hits the ground. This new video analyzes this cycle earlier in the life of the Andover, KS EF3 tornado on April 29, 2022. Please let me know your thoughts! | Reed Timmer Extreme Meteorologist
