Jovian Tropospheric Features—Wind Field, Morphology, and Motion of Long-Lived Systems

A map spanning 360° of longitude and +5° to -65° latitude has been constructed from Hubble Space Telescope SL-9 Campaign F410M images obtained on July 23, 1994 with the WFPC2 in PC and WF mode. For comparison, a map spanning +65° to -65° has been generated from WFPC2 PC observations on February 17, 1995. Because the WFPC2 data has the highest spatial resolution of any data obtained during the SL-9 campaign, these reference maps are intended for general digitized distribution for comparison with other SL-9 data sets. Multicolor images have been utilized to provide fundamental data for interpreting dispersal and evolution of impact sites. Although temporal coverage was less than ideal, a zonal wind profile has been generated from 953-nm images and is comparable to that seen with Voyager. The temporal behavior associated with individual impact sites varies. Impacts that occurred near cyclonic and anticyclonic storms show evidence of interaction with these systems, indicating that winds associated with individual cyclonic and anticyclonic storm centers do not decrease with height as rapidly as the zonal winds. Thus, the translation rates for well-defined anticyclonic cloud systems are tabulated and cyclonic circulation of a storm system which modifies the L-site evolution is characterized.
