Development of a whole atmosphere-ionosphere coupled model for the upper atmospheric research and prediction

我们建立了一个完整的大气-电离层耦合模式，它可以处理从对流层到电离层的整个地球大气区域。结果表明，耦合模式可以再现高层大气中最近观测到的经向变化和逐日变化，并揭示了低层大气对高层大气变化的重要影响。此外，我们还将气象再分析资料加入到耦合模式中，结果表明，该模式和方法对未来高层大气的数值预报是有用的。

We have developed a whole atmosphere-ionosphere coupled model, which can treat the Earth's entire atmospheric regions from the troposphere to the ionosphere. It has been found that the longitudinal dependences and day-to-day variations as recently observed in the upper atmosphere can be reproduced by the coupled model, and revealed that the effect of lower atmosphere is significant for the generation of the upper atmospheric variations. Further, we have incorporated meteorological reanalysis data into the coupled model, and the results suggested that the model and method can be useful for the future numerical prediction of the upper atmosphere.
