摘要

小波方法已经成为一种非常普遍的工具，用于探索和分析太阳数据。已经开发了许多方法。我将简要介绍三种不同的方法:小波功率谱(WPS)，放大图和多分辨率分析(MRA)。然后，我将举例说明小波方法是如何应用于太阳活动指标的。有趣的是，这些研究提出了一些基本问题，即我们所说的太阳活动是什么意思，这些指标有多好。

Wavelet reconstructions of solar magnetic activity

Wavelet methods have become a very much common tool for exploring and analyzing solar data. Many methods have been developed. I will briefly describe three different methods: Wavelet Power Spectra (WPS), Ampligrams, and Multi-Resolution Analysis (MRA). I will then give examples of how the wavelet methods have been applied to indicators of solar activity. Interestingly these studies raise fundamental questions about what we mean by solar activity and how good the indicators are.
