Internal gravity waves have been observed in the Earth’s atmosphere and oceans, on Mars and Jupiter, and in the Sun’s atmosphere. Despite ample evidence for the existence of propagating gravity waves in the Sun’s atmosphere, we still do not have a full understanding of their characteristics and overall role for the dynamics and energetics of the solar atmosphere. Here, we present a new approach to study the propagation of gravity waves in the solar atmosphere. It is based on calculating the three-dimensional cross-correlation function between the vertical velocities measured at different heights. We apply this new method to a time series of co-spatial and co-temporal Doppler images obtained by SOHO/MDI and Hinode/SOT as well as to simulations of upward propagating gravity wave-packets. We show some preliminary results and outline future developments. This article is part of the Theo Murphy meeting issue ‘High-resolution wave dynamics in the lower solar atmosphere’.

一种探测太阳大气重力波的新方法

在地球大气和海洋、火星和木星以及太阳大气中都观察到了内部重力波。尽管有充分的证据表明太阳大气中存在传播的引力波，但我们仍然没有完全了解它们的特征以及它们在太阳大气动力学和能量学中的整体作用。在这里，我们提出了一种研究重力波在太阳大气中传播的新方法。它基于计算在不同高度测量的垂直速度之间的三维互相关函数。我们将这种新方法应用于由 SOHO/MDI 和 Hinode/SOT 获得的时间序列的时空多普勒图像以及向上传播的重力波包的模拟。我们展示了一些初步结果并概述了未来的发展。本文是 Theo Murphy 会议问题“低太阳大气中的高分辨率波浪动力学”的一部分。
