Abstract
In this lecture I try to explain the basic dynamical processes at
work in a radiative zone of a rotating star. In particular, the notion
of baroclinicity is thoroughtly discussed. Attention is specially
directed to the case of circulations and the key role of angular momentum
conservation is stressed. The specific part played by viscosity is
also explained. The old approach of Eddington and Sweet is reviewed and
criticized in the light of the seminal papers of Busse (1981) and Zahn (1992).
Other examples taken in the recent literature are also presented;
finally, I summarize the important points.
