摘要：
近期在太阳表面发现惯性波为了解太阳内部提供了新途径。这些波寿命长，周期与太阳自转周期相当（约27天），且对太阳深处的参数敏感。它们由湍流对流激发，构成了一个被动成像问题。在本研究中，我们提出了基于这些惯性波的交叉协方差观测来重建太阳上的粘性和较差自转的正演与反演问题。
英文摘要：
The recent discovery of inertial waves on the surface of the Sun offers new possibilities to learn about the solar interior. These waves are long-lived with a period on the order of the Sun rotation period ($\sim$27 days) and are sensitive to parameters deep inside the Sun. They are excited by turbulent convection, leading to a passive imaging problem. In this work, we present the forward and inverse problem of reconstructing viscosity and differential rotation on the Sun from cross-covariance observations of these inertial waves.
