Jovian large-scale stratospheric circulation

Structure of the Jovian Stratosphere at the Galileo Probe Entry Site

“…Cooling from C 2 H 2 and C 2 H 6 emissions was included but the C 2 H 2 and C 2 H 6 distributions were assumed to be constant with latitude and altitude. West et al (1992) found that the preponderance of aerosols at high latitudes forced a circulation pattern opposite to that calculated by Conrath et al (1990) with subsidence in equatorial regions. The results from West et al (1992) were used by Friedson et al (1999) to show that the meridional mixing rate of aerosols created in the SL9 collisions was consistent with horizontal eddy mixing derived from the divergence of the Eliasen-Palm flux.…”

These data provide higher spatial resolution than possible with the IUE and Voyager data and the aerosol distribution derived by Moreno and Sedano (1997) has fewer aerosols and therefore less heating than that of West et al (1992) at high northern latitudes.…”

“…Conrath et al (1990) did not consider aerosol heating. West et al (1992) studied the radiative and dynamical structure of the jovian stratosphere using a Transformed Eulerian Mean model to infer diabatic circulation patterns and eddy forcing from observed temperatures and calculations of net radiative heating rates. These authors utilized improved band parameters to calculate energy deposition in CH 4 and paid particular attention to aerosols.…”

The treatment of gaseous opacities was similar in Moreno and Sedano (1997) and West et al (1992), with the exception that the former authors included radiative cooling by NH 3 , which was neglected in earlier studies.…”
