We report the discovery of a convective phenomenon found to occur in a rotating spherical system in which an inner convectively unstable fluid layer is bounded by a corotating outer convectively stable fluid layer. Although convection is thermally driven in the unstable interior, the resulting convective motions concentrate primarily in the stable outer region. This phenomenon, which we term teleconvection, suggests that fluid motions observed at the "surface" of a planet (such as Jupiter's alternating zonal winds) may be driven by an energy source located deep inside the planet.
我们报告了在一个旋转球形系统中发现的一种对流现象,在该系统中,内部对流不稳定的流体层被共旋转的外部对流稳定的流体层所包围。尽管对流是由不稳定内部的热驱动的,但由此产生的对流运动主要集中在稳定的外部区域。我们将这种现象称为远程对流,这表明在行星“表面”观察到的流体运动(如木星交替的纬向风)可能是由位于行星深处的能量源驱动的。
