Gravity wave and the Quasi-biennial oscillation associated with tropospheric variability

利用大气环流模式（AGCM）研究了对流层积云对流产生的赤道俘获波（EQW）和重力内波（GW）。首先，阐明了GWs和EQWs纬向非均匀分布的机制。其次，分析了EQWs和GWs在驱动准两年振荡（QBO）中的作用。最后，研究了全球变暖气候下的准两年振荡。这些结果发表在期刊上。

Equatorial trapped waves (EQWs) and internal gravity waves (GWs) generated by cumulus convections in the troposphere are investigated using an atmospheric general circulation model (AGCM). First, the mechanism of zonally non-uniform distribution of GWs and EQWs was clarified. Next, the roles of EQWs and GWs in driving the quasi-biennial oscillation (QBO) are analyzed. Finally, the QBO in a global warming climate is investigated. These results are published in Journals.
