When an object travels faster than the speed of sound, a sonic boom is created. A ring of pressure waves (probably why wave destruction and pressure cooker are options lol) are created, which is why when you see a jet make a sonic boom there looks like a ring shaped cloud behind it. Hope this helps! For further confirmation/information, just look up sonic boom science (or else you will get sonic boom the video game)

(The same exact thing happens in areas south of the Antarctic Circle in the southern hemisphere. The only difference is that the whole thing is spelled better in the South.)</span>
