And the no - isothermal structure can accelerate the breaking of gravity wave in mesospause, and the breaking of gravity wave is an important source of convection and small - scale waves. the propagation of gravity wave will affect the distribution of minor species. the breaking of gravity wave accelerates the downward transport of atomic oxygen, some smaller - scale structures appear on the horizontal distribution of atomic oxygen number density, and other chemical species are also affected due to the chemical reaction with atomic oxygen and the propagation of gravity wave
在重力波的傳播過程中，氫氧大氣成分的水平和垂直分佈均受到了不同程度的影響，以氧原子的響應最為明顯，而其中重力波破碎在氧原子水平分佈上的反應則是非線性重力波過程的一個重要表現；另外，分析顯示，重力波的非線性傳播對oh氣輝的峰值分佈由明顯影響，小尺度重力波的傳播有時會引起oh氣輝出現奇異的雙峰分佈，重力波的破碎現象也可以從對氣輝的觀測中反映應出來，這對利用氣輝觀測研究重力波傳播特性有非常重要的指示意義。 -
