论文摘要
太阳对流区域深层的对流运动受旋转的影响，从而使对流的热传递纬度依赖于纬度，但在表面附近的顶层中并非如此。我们使用较深层中的热风平衡条件来估计钢备的温度差。该温度差的表面观察可以用于估计近表面层的深度，其中对流不受旋转影响。如果我们要求热风平衡也存在于此层中，那么我们必须得出结论，这必须是强差旋转层及其特征，我们得出的特性与近表面剪切层的观察数据很吻合。
Convective motions in the deep layers of the solar convection zone are affected by rotation, making the convective heat transport latitude-dependent, but this is not the case in the top layers near the surface. We use the thermal wind balance condition in the deeper layers to estimate the pole-equator temperature difference. Surface observations of this temperature difference can be used for estimating the depth of the near-surface layer within which convection is not affected by rotation. If we require that the thermal wind balance holds in this layer also, then we have to conclude that this must be a layer of strong differential rotation and its characteristics which we derive are in broad agreement with the observational data of the near-surface shear layer.
