| 英文摘要 | Saturation and temporal variation of the mean zonal flow in rapidly rotating quasi-geostrophic spherical systems are investigated. Convective instabilities generate highly coherent small-scale eddies that feed energy into the mean flow via the inverse cascade mechanism. We show that this inverse cascade causes a continual piling up of energy in the mean flow, which in turn strongly stabilizes the system and hence dramatically reduces the amplitude of the eddies, leading to the reduction and saturation of the mean flow. This implies that the fast equatorial zonal jets on giant planets may be unsteady. |
