Concerning Various Types of Solar Forcing and their Effects
Variations in solar irradiance (not luminosity !) affect the whole Earth in a way that is controlled by the inclination of solar radiation with respect to the Earth’s surface. But, as J. Lean has said, the spectral distribution also changes and is sensitive to the atmospheric structure, different at high and low latitudes. Moreover, the ionized particles from the Sun are really entering the terrestrial realm from the polar regions, first producing auroral and geomagnetic phenomena.
