在北极冬季平流层环流对全球变暖的动力学响应中，定常行星波的作用是通过分析由规定的海表温度（SST）驱动的耦合模式相互比较项目（CMIP 5）第5阶段的大气模式进行的模拟来研究的。气候模式经常模拟北极平流层的动态变暖，作为对全球变暖的一种反应，与布鲁尔-多布森环流的深层分支的加强有关;然而，到目前为止，还没有提出这种反应的令人满意的机制。这项研究的重点是12月至2月（DJF），因为这是对流层和平流层强烈耦合的时期。当被迫增加SST时，这里分析的所有模型模拟北极平流层动态变暖，主要是由于增加向上传播的准定常波数1，诊断的纬向涡动热通量。此外，它表明，ST…
AbstractThe role of stationary planetary waves in the dynamical response of the Arctic winter stratosphere circulation to global warming is investigated here by analyzing simulations performed with atmosphere-only models from phase 5 of the Coupled Model Intercomparison Project (CMIP5) driven by prescribed sea surface temperatures (SSTs). Climate models often simulate dynamical warming of the Arctic stratosphere as a response to global warming in association with a strengthening of the deep branch of the Brewer–Dobson circulation; however, until now, no satisfactory mechanism for such a response has been suggested. This study focuses on December–February (DJF) because this is the period when the troposphere and stratosphere are strongly coupled. When forced by increased SSTs, all the models analyzed here simulate Arctic stratosphere dynamical warming, mostly due to increased upward propagation of quasi-stationary wavenumber 1, as diagnosed by the meridional eddy heat flux. Further, it is shown that the st...
