在台风的 Mesoscale 波浪被在这篇论文使用一个模仿的台风数据诊断。通过在台风分析波浪的结构,我们发现波浪拥有惯性的波浪和旋涡 Rossby 挥动的严肃的混合特征。在一方面,积极重力势高度不安相应于否定涡度不安和逆旋风的循环。同时,否定重力势高度不安相应于积极涡度不安和气旋的循环。最大的不安在台风发生在最大的风的半径附近。在另一方面,中央规模波浪拥有强壮的集中和分叉和地转风的特征。最后,作者介绍了一个概念模型解释在中央之间的连接机制在台风放大波浪和多角形的眼睛墙的形成。
Mesoscale waves in typhoons were diagnosed by using a simulated typhoon data in this paper. Through analyzing the structure of the waves in typhoons, we found that the waves possess the mixed features of gravity incrtial waves and vortex Rossby waves. On the one hand, positive geopotential height perturbation is corresponding to negative vorticity perturbation and anticyclonic circulation. At the same time. negative geopotential height perturbation is corresponding to positive vorticity perturbation and cyclonic circulation. The maximum perturbation occurs near the radius of the maximum wind in the typhoon On the other hand, the mesoscale waves possess the features of strong convergence and divergence and ageostrophic wind. Finally, the authors presented a concept model to explain a linkage mechanism between the mesoscale waves and the formation of polygonal eye wall in the typhoon.
