Studies of turbulence in gaseous nebulae

We discuss in this work the evidence for the existence of hydrodynamical turbulence in gaseous nebulae. The methods for the statistical analysis of the velocity fields are presented, and the results available in the literature are discussed. As an example, we present an analysis of the velocity fiel...
