circular standing wave

[Ami_Pant_4G]

I am a bit confused about what the standing part of "circular standing wave" means? Can someone please clarify? Thanks in advance.

The circular standing wave is a vibration in which there are points around the circular atom that remain fixed while other points move up and down with maximum amplitude. The wave of electrons forms around the nucleus of an atom, and the waves oscillates with fixed points around the circle with other points moving up and down with said amplitude.

The circular standing wave also shows the general path that the electron follows and how the line must be connected.
