Measurements of wind vectors, eddy momentum transports, and energy conversions in Jupiter's atmosphere from Voyager 1 images
Abstract
Voyager 1 narrow-angle images were used to obtain displacements of features down to 100-200 km in size over intervals of ten hours on February 26-27, 1979. A global map of velocity vectors and longitudinally-averaged zonal wind equation image as functions of latitude are presented. Denoting departures of the zonal and meridional wind from their longitudinal means by u′ and v/u',v′, respectively, the velocity correlation equation image and the meridional gradient du/dy are compared as functions of latitude. A weak but statistically significant positive correlation is found. The implied rate of conversion from eddy kinetic energy to zonal mean kinetic energy is large and may be comparable to the fluxes of solar and internal energy.
