produced by these near surface convection zones. In particular, we examine   whether a link exists between these convective regions and   observable small scale velocity fields at the stellar surface   and in the stellar wind, ``microturbulence". wind,"microturbulence".  A similar idea has been used to explain microturbulence   in low mass stars \cite{Edm78}, in which deeper   envelope convection zones reach the photosphere.
