High-altitude clouds on Neptune have been observed casting shadows on the opaque cloud deck below. There are high-altitude cloud bands that wrap around the planet at constant latitudes. These circumferential bands have widths of 50–150 km and lie about 50–110 km above the cloud deck. [90]
Cloud decks in parallel bands of latitude at and below the tropopause alternately composed of ammonia crystals and ammonium hydrosulfate. Cirriform Bands of cloud resembling cirrus located mainly in the highest of three main layers that cover Jupiter. [28] Stratiform and stratocumuliform Wave and haze clouds that are seen mostly in the middle ...
While cirrus clouds usually form and then disperse within a period of a few hours, the clouds in the Great Dark Spot were still present after 36 hours, or two rotations of the planet. Neptune's dark spots are thought to occur in the troposphere at lower altitudes than the brighter upper cloud deck features. As they are stable features that can ...
Neptune has long been known to have white clouds circling it, but images of the furthest planet in the solar system have shown this changing over time - the most recent image, taken by the Hubble ...
Four years ago, astronomers noticed the abundant clouds on Neptune had largely disappeared. Telescope data may have helped researchers figure out why.

The upper ammonia clouds visible at Jupiter's surface are organized in a dozen zonal bands parallel to the equator and are bounded by powerful zonal atmospheric flows (winds) known as jets, exhibiting a phenomenon known as atmospheric super-rotation. The bands alternate in color: the dark bands are called belts, while light ones are called zones.
