14 lis 2012 · The lower layers of Saturn see higher temperatures and pressures. Water droplets are found here, mixed with ammonia. Saturn boasts some of the fastest winds in the solar system.
16 paź 2011 · In refs 6 and 18 the thermal wind equation is integrated in Saturn’s low-latitude stratosphere by assuming a null wind as the boundary condition around 20 mbar.
19 mar 2010 · Winds in the stratosphere, above the 10-mbar level, seem to vary by ±75 m s −1 with altitude and time in a manner reminiscent of Earth’s quasibiennial oscillation (QBO) (4, 5). Saturn’s large differential rotation, which is larger than that of Jupiter, is still unexplained.
The quasi-biennial oscillation (QBO), dominant in the lower stratosphere, exhibits downward propagating layers of eastward and westward winds (and, from the thermal wind equation, associated warm and cold temperatures at the equator).
8 maj 2008 · The stratosphere of Saturn is a region where temperatures increase with altitude, implying a large static stability and important wave activity.
25 lut 2005 · Stratospheric temperatures on Saturn imply a strong decay of the equatorial winds with altitude. If the decrease in winds reported from recent Hubble Space Telescope images is not a temporal change, then the features tracked must have been at least 130 kilometers higher than in earlier studies.
1 sie 2017 · At higher altitudes, in the stratosphere, Saturn features large, seasonal polar vortices reaching ∼15° away from the pole. Cassini's data series have shown that these vortices form in spring, develop high temperatures and anomalous chemistry during the summer, then dissipate in the autumn and winter.
