Fluid dynamics of polar vortices on Earth, Mars, and Titan

DW Waugh - Annual Review of Fluid Mechanics, 2023 - annualreviews.org
Polar vortices that share many similarities are found in Earth's stratosphere and the

atmospheric structure to vary in both altitude and latitude, to retrieve the spatial distribution …

Organic ices in Titan's stratosphere

CM Anderson, RE Samuelson, D Nna-Mvondo - Space Science Reviews, 2018 - Springer
Titan's stratospheric ice clouds are by far the most complex of any observed in the solar
system, with over a dozen organic vapors condensing out to form a suite of pure and co …
