Abstract

We briefly summarize the status of dynamic model atmospheres for carbon rich red giants and present some recent results of comparisons between synthetic spectra and observations. We then discuss synthetic intensity profiles and visibilities for such stars. In particular, the effects of atmospheric dynamics on different spectral bands and for different model parameters are studied.
