By using a numerical model, effects of the general circulation of the atmosphere on variation of the minor constituents of the atmosphere in the mesosphere and lower thermosphere (MLT), such as atomic oxygen and nitric oxide, were examined. Our results showed that transport processes associated with atmospheric waves played an important role on determining spatial and temporal variations of minor constituent of the atmosphere in the MLT region.These atmospheric waves were generated in the troposphere and propagated into the MLT region, so that it was shown that variations of minor constituents in the MLT region were closely related with variations of the general circulation in the tropsophere.

通过使用数值模型，研究了大气环流对中层和低热层（MLT）大气微量成分（例如原子氧和一氧化氮）变化的影响。结果表明，与大气波相关的传输过程对于确定MLT区域大气微量成分的时空变化起着重要作用。这些大气波产生于对流层并传播到MLT区域，表明MLT区域微量成分的变化与对流层大气环流的变化密切相关。
