A study of middle atmosphere dynamics using a high-resolution climate model

采用具有实际边界条件的重力波解析一般环流模式进行了为期三年的模拟。通过对输出数据的详细分析，从动量平衡、ross - By型和重力型波、重力波的源识别和三维传播、对流层顶和平流层顶的结构和维持机制、准两年一次振荡的驱动机制等方面定量地阐明了中层大气动力学的各种特征。以及中层上层斜压/正压不稳定的动力学。

A three-year simulation was performed using a gravity wave-resolving general circulation model with realistic boundary conditions. By analyzing the output data in detail, various features of the middle atmosphere dynamics have been clarified quantitatively in terms of the momentum balance including both Rossby-type and gravity-type of waves, the source identification and three-dimensional propagation of gravity waves, the structure and maintenance mechanisms of the tropopause and stratopause, the driving mechanisms of the quasi-biennial oscillation, and the dynamics of baroclinic/barotropic instabilities in the upper mesosphere.
