最近的观察表明，太阳活动和平流层冬季北半球环流的强度之间可能存在因果关系。建立了一个10-140公里大气层的三维模型，以评估太阳最小和最大条件对行星波传播的影响以及随后对平流层环流的变化。为了强调非线性动力耦合的重要性，中层大气中的紫外线加热保持不变。通过将上层温度松弛到MSIS-90经验温度模型，得到了一个真实的热球。在夏季半球，强烈的辐射衰减阻止了显著的动力耦合发生。在动态控制的冬季半球内，微小的扰动在很长一段时间内得到加强，导致平流层环流的系统性变化。根据报告的30毫巴位势高度和臭氧总量的测量，冬季涡旋在太阳最大值和准两年振荡的西相期间显著减弱。
Recent observations suggest that there may be a causal relationship between solar activity and the strength of the winter Northern Hemisphere circulation in the stratosphere. A three-dimensional model of the atmosphere between 10–140 km was developed to assess the influence of solar minimum and solar maximum conditions on the propagation of planetary waves and the subsequent changes to the circulation of the stratosphere. Ultraviolet heating in the middle atmosphere was kept constant in order to emphasise the importance of non-linear dynamical coupling. A realistic thermo-sphere was achieved by relaxing the upper layers to the MSIS-90 empirical temperature model. In the summer hemisphere, strong radiative damping prevents significant dynamical coupling from taking place. Within the dynamically controlled winter hemisphere, small perturbations are reinforced over long periods of time, resulting in systematic changes to the stratospheric circulation. The winter vortex was significantly weakened during solar maximum and western phase of the quasi-biennial oscillation, in accordance with reported 30 mb geopotential height and total ozone measurements.
