Abstract

Convection and turbulence in the atmospheres of A-types and cooler stars produce observable effects. A discussion of the 1-D parameterization via mixing-length, microturbulence and macroturbulence is presented, along with a comparison of various calibrations. Overcoming some of the limitations of 1-D model atmospheres, 2-D and 3-D hydrodynamic simulations can yield improved fits to observed line profiles without the need for these parametrisations.
