查询词典 water structure

Despite the Rossby Radius of Deformation around strong vortexes is much smaller than of the background, the results of experiments in the nondivergent barotropic model and in the shallow water model are similar. This indicates that there is little differences between vorticity dynamics and potential vorticity dynamics in the formation of the concentric eyewall structure of typhoons. The dynamics of this formation belongs to a slow manifold dynamics and the effect of the gravity waves is limited.

我们以浅水模式延续前人之正压双涡旋实验，虽然强涡旋周围的罗士比变形半径远小於背景环境值，但是涡旋交互作用结果和正压模式类似，亦即涡度动力和位涡动力在强台风形成双眼墙的结构之下并没有很大不同，皆属於慢速流形动力，重力波造成的影响很有限。
