也谈Rossby长波理论及其“悖论”
Discussion on the Issue of Rossby Waves Theory and Its “Paradox”
中文摘要：
鉴于罗斯贝长波理论无辐散假定与物理学波动概念之间的矛盾，文章讨论了牵连涡度和相对涡度之间的相互转换实际上都需要通过散度才能实现。从地转适应理论的角度看，罗斯贝无辐散的假定实际上是假定地转适应过程无限快，和物理学的波动概念并不抵触。最后从流线和轨迹的区别分析了长波中散度的分布特征及其与长波移速在物理上的关联。

Abstract：
en implicated vorticity and relative vorticity is practically required by divergence. From the view of the geostrophic adaptation theory, the nondivergent assumption of Rossby is actually assumed that the process of the geostrophic adaptation is infinitely fast, which does not contradict the concept of physics fluctuation. Finally, the distribution characteristics of divergence in long wave and its physical correlation with long wave velocity are analyzed based on the difference between streamline and trajectory.
