Heat is transported through the outermost 30% of the Sun's interior by overturning convective motions. These motions are evident at the Sun's surface in the form of two characteristic cellular structures: granules and supergranules (~1000 and ~30,000 kilometers across, respectively). The existence of much larger cells has been suggested by both theory and observation for more than 45 years. We found evidence for giant cellular flows that persist for months by tracking the motions of supergranules. As expected from the effects of the Sun's rotation, the flows in these cells are clockwise around high pressure in the north and counterclockwise in the south and transport angular momentum toward the equator, maintaining the Sun's rapid equatorial rotation.
热量通过太阳内部最外层的 30%通过翻转对流运动进行传输。这些运动在太阳表面以两种特征的细胞结构形式表现出来：米粒组织和超米粒组织（分别约为 1000 和 30000 公里）。超过 45 年的理论和观测都表明，更大的细胞的存在。通过跟踪超米粒组织的运动，我们发现了持续数月的巨型细胞流的证据。正如太阳自转的影响所预期的那样，这些细胞中的流动在北部高压处顺时针流动，在南部逆时针流动，并将角动量输送到赤道，从而保持太阳的快速赤道自转。
