The PIs will investigate the influence of the solar cycle on the general circulation of the stratosphere and troposphere. Decadal variations operating coherently with the variation of the ultra-violet (UV) radiation will be investigated in long records of dynamical and chemical structure characterizing the circulations of the stratosphere and troposphere. Building on recent evidence, this investigation will examine the four-dimensional record of National Centers for Environmental Prediction (NCEP) reanalyses to isolate those months and locations, inclusive of the Southern Hemisphere, tropics and troposphere, for which interannual changes operate dependently with changes of ultra-violet (UV) irradiance. Contemporaneous changes of ozone will be investigated in records from station data and in the satellite record from total ozone mapping spectrometer instrument (TOMS). The work is important because it will enhance our understanding of solar-climate interactions.

研究员将调查太阳活动周期对平流层和对流层大气环流的影响。将在描述平流层和对流层环流特征的动力学和化学结构的长期记录中研究与紫外线辐射变化一致的十年变化。根据最近的证据，这项调查将检查国家环境预测中心（NCEP）再分析的四维记录，以隔离那些月份和地点，包括南半球，热带和对流层，其中年际变化与紫外线（UV）辐照度的变化相关。将在台站数据记录和臭氧总量测绘光谱仪的卫星记录中调查臭氧的同期变化。这项工作很重要，因为它将增强我们对太阳-气候相互作用的理解。
