摘要：

We studied SUMER and CDS time series of spectra and images of quiet-Sun regions at disc centre. Ultraviolet emission lines sampling temperatures of the chromosphere, transition region and corona were recorded. We found a high correlation between average net Doppler shifts and relative brightness variabilities of the studied lines. We point to some basic ideas which could eventually model the variability-Doppler shift relationship.
