Paper Abstract

Our perspective of Cn2 in low stratus clouds and their associated subcloud regions is developed in this paper. In so doing, two environments are 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 ambient environment, assuming that the turbulent parcels are weakly conservative and passive; whereas, our definition of "optical turbulence" is used to address the rising parcel where conditions are not conservative and passive. Vertical profiles of n, dn/dz, and Cn2 associated with the rising parcel and those associated with the ambient atmosphere are presented for one set of conditions.
