A multiscale flow field in the turbulent atmosphere gives
rise to multiscale variation in the index of refraction.
We consider a situation where waves propagate through a random
medium with an index of refraction which exhibit multiscale
variations. We examine how the wave field is affected by such medium
heterogeneity. We also discuss results from
analysis of physical measurements from the turbulent
atmosphere with a view toward modeling of the random medium.
