Amazing Satellite Animation of the Volcanic Pressure Wave

Saturday, we walked about the barometric pressure wave from the Tonga volcano explosion as it moved across the United States. For example, the red line (below) shows the very rapid fluctuation in barometric pressure at Washington, DC. 

The Pacific GOES-17 weather satellite's sensors (not of the type you see in television weathercasts) was used to created an animation of the wave as emanated from the eruption. A screen capture is below.

The animation is here. Just amazing. Thanks to William Barlow for the animation.
