Effect of the solar Ultra-Violet radiation(UV) on the Southern Annular Mode(SAM) was examined through the analysis of observational data and simulations of a chemistry-climate model. When the solar activity is higher and the UV is stronger, the Polar-night Jet Oscillation(PJO), which is the dominant mode of variability of the stratosphere-troposphere coupled system in late winter/spring, is found to be more enhanced and stronger SAM signal is created at the surface. Analysis of simulations of chemistry-climate model with changing UV strengths suggests that such solar UV-SAM relationship was created through enhanced wave-mean flow interaction originated from increases of ozone and temperature in the stratosphere under high solar UV condition.

通过观测数据分析和化学气候模型模拟，研究了太阳紫外线辐射（UV）对南环模（SAM）的影响。当太阳活动较高且紫外线较强时，极夜急流振荡（PJO）（冬末/春季平流层-对流层耦合系统的主要变化模式）会更加增强，并且在地表产生更强的 SAM 信号。对具有变化的紫外线强度的化学气候模型的模拟分析表明，这种太阳紫外线-SAM关系是通过增强的波平均流相互作用而建立的，这种相互作用源于高太阳紫外线条件下平流层中臭氧和温度的增加。
