Solar turbulent convection probed by helioseismology (A01)

在第二个资助期，我们将重点研究局部日震学的非线性反演，这是当流动扰动不弱时所需要的。为了限制正问题的数值解的数量，我们将使用预置牛顿- cg方法。此外，我们将直接从旅行时间的相关性中反演对流雷诺兹应力，特别是研究它们对纬度的依赖。这将有助于我们对太阳对流区全球动力学的理解。

In the second funding period we will focus on nonlinear inversions for local helioseismology, which are required when flow perturbations are not weak. To limit the number of numerical solutions of forward problems, we will use preconditioned Newton-CG methods. Moreover, we will directly invert for convective Reynolds stresses from correlations of travel times, studying in particular their dependence on latitude. This will contribute to our understanding of the global dynamics of the solar convection zone.
