太阳活动影响气候的放大过程之时空选择性

摘要

Solar is one of the original driving forces for the earth climate formation, however, how much inlfuence 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 inlfuence 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 Paciifc Ocean can be ampliifed by the monsoon activity, and ultimately affect the global climate.%太阳是形成地球气候的原始驱动力之一，但太阳活动变化对气候的影响究竟有多大，其机制和途径是什么，是否存在放大效应，一直是有争议的一个问题。结合国家重大科学研究计划“天文与地球运动因子对气候变化的影响研究”一些研究进展，综合归纳了太阳活动变化对气候系统一些关键环节的影响和作用，阐述了气候系统对太阳活动的响应具有显著的时空选择性。指出太阳活动通过季风活动通道，可能将太阳活动对极区和西太平洋热带对流区的影响放大，并最终影响全球气候。
