On Earth a pattern of highs and lows is caused by some gases spiraling up, while in other places gases are spiraling down (like water flowing out of a bath drain). But on Jupiter these eddies are immense—many bigger than
our Earth! They are also coloured, often with light pinks, yellows, and white, the significance of which is unclear.
On Earth the highs and lows often move from the tropics toward the poles and vice versa. That is because they are moving between regions of cold and warmth. In particular, they are often associated with regions of land and ocean. On Jupiter they appear to be trapped at definite latitudes. That may be because Jupiter has no big temperature contrasts like the Earth and has no land or ocean, just a deep mass of gas.
anticyclone A roughly circular region of the atmosphere that is spiraling outward and downward.
cyclone A large storm in which the atmosphere spirals inward and upward.
great red spot A large, almost permanent feature of the Jovian atmosphere that moves around the planet at about latitude 23°S.
latitude Angular distance north or south of the equator, measured through 90°.
pole The geographic pole is the place where a line drawn along the axis of rotation exits from a body’s surface.
