Barbara, J.M., and A.D. Del Genio, 2020: Tropopause and lower stratosphere winds and eddy fluxes on Saturn as seen by Cassini Imaging. Icarus, submitted.

An automated cloud feature tracking algorithm is applied to Cassini Imaging Science Subsystem images in continuum, methane band, and ultraviolet filters to derive zonal wind profiles and eddy momentum fluxes from the middle troposphere cloud tops to the lower stratosphere. Zonal winds in the eastward and westward jets decrease in strength from the cloud tops to the upper troposphere, but are indistinguishable from the upper troposphere to the tropopause to the lower stratosphere. A narrow equatorial jet is detected at the cloud tops, but a previously reported strengthening of this jet at higher altitudes cannot be verified due to an absence of easily trackable features at the equator and conflicting results for the few features available. Eddy momentum fluxes on either side of the jet cores outside the equatorial region appear to weaken from the visible cloud level to the upper troposphere but may increase from the upper troposphere/tropopause levels to the lower stratosphere.
