The hexagonal, pole-centered cloud feature in Saturn's northern atmosphere, as revealed in Voyager close-encounter imaging mosaics, may be interpreted as a stationary Rossby wave. The wave is embedded within a sharply peaked eastward jet (of 100 meters per second) and appears to be perturbed by at least one anticyclonic oval vortex immediately to the south. The effectively exact observational determination of the horizontal wave number and phase speed, applied to a simple model dispersion relation, suggests that the wave is vertically trapped and provides a diagnostic template for further modeling of the deep atmospheric stratification.
航海者号近距离成像镶嵌图揭示，土星北极大气层中呈六边形、极点为中心的云特征可能是一种定常罗斯贝波。该波嵌入在一个急剧尖峰的向东射流（每秒 100 米）中，并且似乎受到至少一个位于南部的反气旋卵形涡旋的干扰。对一个简单的模型频散关系应用有效精确的观测水平波数和相速度的确定，表明该波是垂直捕获的，并为进一步对深大气分层的建模提供了诊断模板。
