Research Abstract

We examine formulation of the governing basic equations that describe developments of a protoplanetary accretion disk, and discuss applicability of various concepts of geophysical fluid dynamics to its fluid motions, and reconsider the structures of basic fields and disturbances. We confirm that the condition that should be satisfied by axisymmetric fields of geophysical fluid dynamics should be satisfied also for the nebula gas fields of protoplanetary accretion disk. However, it seems that the structure of disturbances is quite different from that of baroclinic unstable disturbances of geophysical fluid dynamics.
