Total solar irradianee variation and the solar activity cycle

摘要

It is shown that multiple periods of the total solar irradianee data within the solar activity cycle indicates that there are multiple phases e.g., five phases in the solar activity cycle as in the sunspot numbers data, solar magnetic data, solar neutrino flux data, solar proton data, etc. We suggest that all the phases are different from one another indicating the different physical conditions on the surface (temperature, magnetic fields, active netwoik components etc.) during the solar activity cycle.
