Paper Abstract

Results of numerical calculations of internal wave breaking and turbulence production in the mesosphere are used to compute parameters describing the propagation of a laser beam from the ground upward. Peak values of C2n of about 7 x 10-18m-2/3 at a height near 40 km. are computed. The impact of the wave breaking is greatest on parameters described by integrals with height-weighted integrands; the isoplanatic angle is reduced by 75% below the value it has before breaking commences. On the other hand, the variance of the log relative amplitude is increased by 5%, and the transverse coherence length is decreased by a like amount.
