Solar influence on regional climate thought stratospheric process

通过观测和化学气候模式研究的结合，阐明了太阳通过平流层动力过程的影响。结果表明，平流层环流的变化可以通过与海洋的相互作用在对流层中持续更长的时间，从而产生区域差异。在太阳活动高峰期，由于温室气体增加而产生的平流层冷却效应更容易传播到对流层，并在海平面气压中产生类似北大西洋振荡的模式。

Solar influence through the stratospheric dynamical processes is clarified by combination of the observational and chemical-climate model studies. It is shown that the stratospheric circulation change can persist longer in the troposphere through interaction with the oceans, creating regional differences. During the period of high solar activity, stratospheric cooling effect due to the increased greenhouse gases propagates more easily to the troposphere and creates North Atlantic Oscillation-like pattern in the sea-level pressure.
