3.  Influence of Jupiter's South Equatorial Disturbance on jet-stream speed;
by John H. Rogers & Hans-Jörg Mettig

SUMMARY:
The eastward jets on Jupiter are, with few exceptions, remarkably invariant.
However, we now report considerable diversity of speeds in one of the
fastest jets, at 7ºS. We present ground-based observations from 1999 to
2006, which are shown to agree with measurements of the same region from
Cassini spacecraft images. All the measurements refer to small cloud
features seen as 'chevrons' in spacecraft images, which appear to represent
the peak speed of the jet at or near cloud-top level.  Previous
discrepancies in measurements for this jet are resolved by showing that the
speeds vary with longitude relative to a large wave-like feature, the South
Equatorial Disturbance (SED).  The SED has persisted from 1999 to 2006, and
a similar feature was present during the Voyager flybys.  When the SED is
present and active, as it was during the Voyager and Cassini flybys, the
observed jet speed is slow to the east of it (~116-128 m/s) but rapid to the
west of it (~142-162 m/s).  When the SED is absent (as in the mid-1990s) or
weak (as in 2002-2005), it no longer modulates the observed speeds in the
jet: a rapid jet speed of ~155 m/s is observed at all longitudes, but some
individual features move more slowly over shorter intervals.  These velocity
patterns have implications for the physical nature of the SED and for the
vertical structure of the jet at 7ºS.

Summary:

Jupiter's eastward jet at 24°N, which formerly had the fastest winds on the planet, has maintained a less extreme speed of ~135 m/s since 1991, carrying a series of long-lived vortices at 125 m/s.  In 2002-2003, as the albedo of the adjacent North Temperate Belt increased, the tracks of the vortices accelerated slightly, and they had disappeared by 2005.  In 2005, small tracers had a mean speed of 146.4 (+/- 0.9) m/s, significantly faster than the previous mean speed of the jet, suggesting that the jet peak itself has accelerated at cloud-top level, and that the jet is beginning to return to the super-fast state.  These changes may resemble the even greater transformations occurring in the equatorial jet of Saturn.

Summary:

The dynamics of mergers of large circulations in Jupiter's atmosphere may permit different models of the atmosphere to be tested.  We report well-resolved observations of such events at visible wavelengths: three anticyclonic and three cyclonic events.  A merger of anticyclonic white ovals in the South South Temperate domain (2002 March) is compared with the previously reported merger of ovals BE and FA in the South Temperate domain (2000 March).  In each case, the two similar-sized ovals converged rapidly once they were separated by less than the sum of their diameters; they orbited around each other anticyclonically during the merger; the merged oval initially had the same rapid drift as the western parent; and, in an unexpected similarity, a cyclonic oval emerged westward from the point of merger.  Evidence suggests that a merger of smaller ovals in the North North Temperate domain (2002 February) had similar dynamics.  In contrast, mergers of cyclonic ovals in the North Equatorial Belt ('barges': 2001 November, 2005 May) proceeded in a different manner.  The two parent barges showed no consistent acceleration towards each other as they converged; on contact there was no obvious sign of mutual circulation, and the low-albedo regions had almost passed each other before they finally merged; and the resulting barge had a drift rate intermediate between the two parents, and a length that was greater than either parent.  Again, a third such event involving a smaller barge (2002 December) showed many of the same characteristics.  These observations define different dynamical behaviour during anticyclonic and cyclonic mergers.
