Eddy Mixing Coefficient On
Data on the composition and thermal structure, and the Lyman-alpha dayglow of Saturn when analyzed in conjunction with photochemical models of the hydrocarbons and the atomic hydrogen g reduction yield the homopause value of the eddy diffusion coefficient to be approximately 10 cm2 s-l. The equatorial value of the eddy diffusion coefficient at the homopause of Saturn is thus found to be approxi...
متن کاملHydrocarbons and Eddy Mixing in Neptune’s Atmosphere
The most recent analysis of the Voyager ultraviolet solar occultation observations at Neptune indicates a methane mixing ratio 1-10 times above saturation in the lower stratosphere, unlike the value of 500-1000 times saturation which was suggested just before the encounter of Voyager with Neptune. The acetylene mixing ratio in the 0.1 mb region is found to be (6 8) x 10-8, which is approximatel...
متن کاملHorsing around on Saturn.
On the basis of simple statistical mechanical models, the prevailing view of the rings of Saturn is that they are unstable and must therefore have been formed rather recently. In this paper, we argue that the Saturn rings and inner moons are in much more stable orbits than previously thought and, therefore, that they likely formed together as part of the initial formation of the solar system. T...

An atmospheric electrical method to determine the eddy diffusion coefficient
The ion–aerosol balance equations are solved to get the profiles of atmospheric electric parameters over the ground surface in an aerosol-rich environment under the conditions of surface radioactivity. Combining the earlier results for low aerosol concentrations and the present results for high aerosol concentrations, a relation is obtained between the average value of atmospheric electric spac...
