چکیده انگلیسی
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.
