The Morphogenesis of Bands and Zonal Winds in the Atmospheres on the Giant Outer Planets

Cho, James Y-K., Polvani, Lorenzo M.·1996·Science

Abstract

The atmospheres of Jupiter, Saturn, Uranus, and Neptune were modeled as shallow layers of turbulent fluid overlying a smooth, spherical interior. With only the observed values of radius, rotation rate, average wind velocity, and mean layer thickness as model parameters, bands and jets spontaneously emerged from random initial conditions. The number, width, and amplitude of the jets, as well as the dominance of anticyclonic vortices, are in good agreement with observations for all four planets.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Alternating jets on gas giant planets are either shallow, existing above about 10 bars, or deep, extending to tens of thousands of bars.

    “on one hand, the alternating jets on gas giant planets are 'shallow', existing above 10 bars or so [15-17]; on the other hand, zonal jets are 'deep', extending to tens of thousands of bars [18-22].”
  • The latitudinal difference in jet and vortex structure is likely driven by the topographical beta effect, which is stronger near the equator and promotes axisymmetric jets, while at higher latitudes the beta effect decreases and the system approaches a rotating plane layer where giant vortices are favored.

    “This is likely driven by the topographical β effect, due to the spherical shell geometry, which is stronger near the equator, promoting strong axisymmetric jets, while, at higher latitudes, the β -effect decreases and the system approaches a rotating plane layer where the formation of giant vortices is favored”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
