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.

利用大气环流模式（AGCM）研究了对流层积云对流产生的赤道捕获波（EQWs）和内部重力波（GWs）。首先，阐明了GWs和EQWs纬向不均匀分布的机理。其次，分析了EQWs和GWs对准两年振荡的驱动作用。最后，对全球变暖气候下的QBO进行了研究。这些研究结果发表在期刊上。
