When east wind stress anomaly and meridional wind stress anomaly happen the La Nina events occur. 当东风应力异常偏强及经向风应力异常向赤道南北两侧辐散偏强则与LaNina事件对应。
The magnitude of seasonally meridional migration in the location of the primary Polar Front ( PF1) is much less than that of the climatic monthly mean zero wind stress curl, but is near the mean position of zero wind stress curl. 第一极锋(PF1)位置的经向季节变化幅度远小于气候月平均零旋度线的经向季节变化幅度,但位于零旋度线的平均位置附近。
We suggested that the meridional structures and the east structures of Sichuan form at the same time, and that the asymmetry distribution of the structure force in the southeastern edge of Sichuan basin, that the stress direction move to south continuously. 提出近南北向构造是川东构造形成时期,四川盆地东南部边缘构造力的不均匀分布,导致应力向南不断转向而形成的。
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。
We also draw a conclusion that the zonal wind stress is more important than the meridional wind stress in creating El Nino/ La Nina evolution. 说明在生成ELNino/LaNina事件的重要性上,纬向风应力的振荡成分比经向风应力的更重要,作用也更显著。
In addition, warm water is recruited to the equator district strongly at the west boundary, which indicates that meridional wind stress may have warm water conveyed to the equator. West wind stress has warm water at the west boundary conveyed easterly. 另外,在西边界处存在很强的暖水补充到赤道的现象,经向风应力有使暖水向赤道输送的作用,而西风应力使西边界处的暖水向东输送。
West wind stress anomaly and meridional wind stress anomaly occur in the east of tropic Pacific, which can boost the formation of EL Nino events. The stronger wind stress anomaly, the stronger the corresponding EL Nino event. 热带太平洋东部伴随着西风应力异常以及向赤道辐合的经向风应力异常,能够有利于驱动ELNino事件的形成,而且当风应力异常强则对应的那次ELNino事件也偏强;
Diagnostic results show that the westerly wind stress anomaly and convergent meridional wind stress anomaly over the tropical Pacific correspond to the every El Nino, and the easterly anomaly and divergent meridional wind stress anomaly correspond to the vanishing of El Nino. 通过研究表明,每次ELNino事件在热带太平洋都伴随着西风应力异常以及向赤道辐合的经向风应力异常,东风应力异常及向两极辐散的经向风应力异常与ELNino消亡对应。
So the meridional wind stress in the ECS Kuroshio area is calculated. Its seasonal variation is very similar with the upper transport across the PN section. 计算了东海黑潮区域的平均经向风应力,季节变化与东海黑潮上层输送量的季节变化类似。
With the help of POD method, more wind pressure series can be regenerated, by the way of finite element analysis, dynamic displacement and meridional stress response of cooling-tower shell is obtained. 采用POD方法对冷却塔表面风压的测点进行加密,并进行有限元的时程响应分析,计算得到了冷却塔位移、子午向应力等响应的平均值和脉动值。
