There is strong evidence indicating that solar activity indicators exhibit temporal relationships, summarized in a basic manner as time delays of indicators of the upper solar atmosphere versus indicators related to the solar photosphere. These time delays have magnitudes on the order of several weeks, are indicator-dependent and possibly solar-cycle-dependent, and are caused by differences among indicators from different source regions.
We further identify and classify these temporal relationships through use of short-term and long-term time series of global solar indicators and through use of image sequences of developing active regions. Our analyses of indicator time series involve both the time domain and the frequency domain using the following space-based and ground based indicators: Lyman-alpha 121.6-nm flux, Mg II 280-nm core-to-wing ratio, Ca II K 393.3-nm emission index, He 1083-nm equivalent width, and 10.7-cm microwave flux. We are also beginning modeling efforts to link short-term and long-term effects and to test our analysis methods.
