Abstract: Solar is one of the original driving forces for the earth climate formation, however, how much influence does the solar activity on the earth climate? What are the mechanisms and modes involved in the progresses? And the amplification effect proposed by predecessors is still on debate. Based on the advances in the national basic research program of China that "a study of impacts of astronomical and earthly motility factors on climate change", this paper provides an overview of the influence and effect of solar variability on some critical components of climate system. The spatio-temporal selectivity in the climate system responses to solar activity forcing is described. We point out that the solar activity effect on polar region and convective region over tropical Pacific Ocean can be amplified by the monsoon activity, and ultimately affect the global climate.
