在本文中,我将回顾最近的进展,我们的理论认识的太阳速跃层。这层强烈的径向和纬向差异旋转在太阳对流区的底部被认为是在太阳磁场的产生中起着至关重要的作用。我将审查的位置,大小和时间的变化的速度跃层的意见,讨论竞争理论之前,其形成。然后,我将描述可能的不稳定机制的速跃层和它的作用,在产生太阳的磁场发电机行动。
In this paper I shall review recent progress in our theoretical understanding of the solar tachocline. This layer of strong radial and latitudinal differential rotation at the base of the solar convection zone is believed to play a vital role in the generation of the solar magnetic field. I shall review the observations of the location, size and temporal variability of the tachocline, before discussing competing theories for its formation. I shall then describe possible instability mechanisms of the tachocline and its role in generating the Sun's magnetic field by dynamo action.
