What a lovely comment! Is there a term that describes the sort of oscillation you're talking about, by the way? Wherein object A is embedded 'within' object B?

  I don’t know of a good term, no. “Differential rotation” is the broader concept but almost all of the information there is about bodies of fluids, with not much treatment of discrete objects. Even a single discrete object inside a body of fluid is hard to find information on; “object A inside shell B, all in a fluid C” is probably asking too much. Hopefully someone does, though! This is probably one of those cases where if you know the right term you can access a whole hidden field of literature on the topic.

    Would fluid-structure interaction [1] with encapsulated systems fit the bill? It’s a subset of continuum mechanics which is probably the best field to model the layers of atmosphere as a mix of solid and fluid continuums and oscillatory systems are a defining feature of the field: > Fluid–structure interaction (FSI) is the interaction of some movable or deformable structure with an internal or surrounding fluid flow. Fluid–structure interactions can be stable or oscillatory. In oscillatory interactions, the strain induced in the solid structure causes it to move such that the source of strain is reduced, and the structure returns to its former state only for the process to repeat.
