1·The meridional stress in the gore centerline is considered, and a biaxial stress model is got.

考虑伞衣中线上的子午向应力，得到了一个双轴应力模型。

2·The results show that the oscillations of zonal wind stress have 35 47 57 months, the oscillations of meridional wind stress have 28 38 months.

结果显示：纬向风应力有35、47和57个月周期的传播型振荡； 经向风应力有28和38个月周期的传播型振荡。
