  Increasingly sophisticated observational tools and techniques are now being
developed for probing the nature of interstellar turbulence. At the same time,
theoretical advances in understanding the nature of turbulence and its effects
on the structure of the ISM and on star formation are occurring at a rapid
pace, aided in part by numerical simulations. These increased capabilities on
both fronts open new opportunities for strengthening the links between
observation and theory,and for meaningful comparisons between the two.
