扰动涡 meaning in English
disturbance vortex
Examples
- The radial advection of vorticity plays a major role in the inward - propagation process of vorticity , and the nonlinear advection of perturbation vorticity may enhance the inward - propagation of vorticity , which results in the locally strengthening of the typhoon circulation
径向平流在涡量内传过摘要程中起主要作用，扰动涡量的非线性平流可以加强涡量内传。内传的涡量可以引起台风局域加强。 - The main results can be summarized as the folio wings : in the certain parameter range , the circular shearing basic flow might be able to axisymmetrize the one - wave asymmetric structure of a typhoon and also to transfer the perturbation vorticity in the outer region inwards
主要结果可以归纳如下：在一定的参数范围，圆形切变基流可以使初始一波非对称结构轴对称化，也可以使外区的扰动涡量向内传播。 - The phenomena of initial disturbance vorticity translating into spiral bands is most evidently for it locating at the periphery of radius of maximum wind ( rmw ) , near rmw next and the spiral bands vanish when it is positioned in the inner core region . indicating that the farther the distance from the tc center , the more distinctly the spiral bands and the opposite is true
初始圆形扰动涡度场转化为螺旋臂涡量带的现象是初始扰动位于涡旋最大风速半径( rmw )外围最显著，其次是rmw附近，当扰动位于涡旋内核区时几乎没有螺旋臂结构形态出现，表明，初始扰动离tc中心越远，其强迫涡旋rossby波形成的螺旋带结构越明显，反之越弱。
