使用耦合化学气候模型的新模拟来检查臭氧和温度的 11 年太阳周期。结果显示平流层热带臭氧存在次极大值，与卫星观测结果一致，但与大多数先前发表的模拟结果相反。在典型的太阳活动周期中，臭氧的平均模型响应变化约 2.5%，温度的平均模型响应变化约 0.8 K，处于观测到的峰值响应范围的下限。高能粒子的高层大气效应和准两年期振荡的存在都不是模拟观测到的低纬度臭氧浓度中平流层下部响应所必需的。模型模拟和观测到的总柱臭氧也进行了比较。与之前的研究一样，模型模拟与观测结果吻合良好。对于那些覆盖1960-2005年整个时间范围的模型，50 hPa以下的臭氧太阳信号从前两个太阳周期到最后两个太阳周期发生了很大变化。进一步的调查表明，这种差异是由于该时期第一部分的海面温度和太阳周期之间的混叠造成的。讨论了这些结果与热带日光带响应的整体结构之间的关系。对太阳过程的进一步了解需要改进垂直变化和柱积分臭氧的观测。
The 11-year solar cycles in ozone and temperature are examined using newsimulations of coupled chemistry climate models. The results show a secondary maximumin stratospheric tropical ozone, in agreement with satellite observations and in contrastwith most previously published simulations. The mean model response varies by upto about 2.5% in ozone and 0.8 K in temperature during a typical solar cycle, at the lowerend of the observed ranges of peak responses. Neither the upper atmospheric effectsof energetic particles nor the presence of the quasi biennial oscillation is necessaryto simulate the lower stratospheric response in the observed low latitude ozoneconcentration. Comparisons are also made between model simulations and observed totalcolumn ozone. As in previous studies, the model simulations agree well with observations.For those models which cover the full temporal range 1960–2005, the ozone solarsignal below 50 hPa changes substantially from the first two solar cycles to the last twosolar cycles. Further investigation suggests that this difference is due to an aliasingbetween the sea surface temperatures and the solar cycle during the first part of the period.The relationship between these results and the overall structure in the tropical solarozone response is discussed. Further understanding of solar processes requiresimprovement in the observations of the vertically varying and column integrated ozone.
