摘要
本文采用ＷＫＢ方法，讨论了地形正压Ｒｏｓｓｂｙ波的发展与结构变化问题。指出波动的发展和衰减不仅与波幅和波长的增减有关，还与波的结构状态有关。
In this paper,WKB method is applied to discuss the development and the change of structure of topographic barotropic Rossy wave. The results indicate that the evo- lution and attenuation of waves are related to not only the increase and decrease of wave am- pliude and wave-length but also the state of wave trough.
