(2003); and the black line from Simon et al. (2015). The three wind profiles match at most latitudes; small differences are often associated with features (such as storms and disturbances) that have different velocities from the general winds. From Simon et al. (2015), "First results from the Hubble OPAL program: Jupiter in 2015"
