Paper Abstract

This paper is an update of a paper of the same title presented to SPIE in 1989. A new perspective of Cn2 in low stratus clouds and their associated subcloud regions is developed in this paper. Two environments are still considered, that of a rising parcel and that of the ambient environment, resulting in two vertical profiles of Cn2. An extension of Tatarski's formulations is used to characterize the environments, assuming that the turbulent parcels are weakly conservative and passive. Vertical profiles of the mean refractive index, the part of the gradient of the mean refractive index that does not adjust immediately when a parcel is displaced vertically, and Cn2 associated with the rising parcel and those associated with the ambient atmosphere are presented for one set of conditions in a stable atmosphere.
