Abstract

Robust and high spatial resolution observations made by Hinode enable us to understand waves in the solar atmosphere. It also enables us to estimate the energy supplied by waves and to discover the dissipation processes of waves. Moreover, by specifying the wave modes and estimating plasma density using spectroscopy, precise measurements of the coronal magnetic field can be obtained, which are now available. However, if we interpret all periodic events as waves, we will miss out on some important features, such as mass flows. In this document, I will explain energy transfer and magnetic field estimation using waves and quasiperiodic upflows that have observational features similar to those of waves.

Hinode is a Japanese mission developed and was launched by ISAS/JAXA, with NAOJ as domestic partner and NASA and STFC (UK) as international partners. It is operated by these agencies in cooperation with ESA and NSC (Norway). The authors thank S.Imada and S.Ueno for their fruitful comments on this manuscript.
