Tom Yulsman shared this storm animation on Youtube!
This spectacular animation of GOES-16 weather satellite images shows severe storms boiling up over southern Illinois, where they dumped heavy rainfall on April 28, 2017. The images were acquired by the satellite in intervals of 30 seconds, allowing for a near-real-time view of the developing storms.
The momentum of the updrafts in the cores of the thunderstorms were so strong that the air parcels punched through from the lower level of the atmosphere, the troposphere, into the stratosphere. This phenomenon is called “overshooting tops.” As air parcels subsided back down, rose up, and settled again, the result was a wave-like phenomenon in the clouds. If you look carefully you might see something akin to what happens when a stone is tossed into a pond. These features are called “gravity waves.”
