( 5 ) the decadal variations of quasi - quadrennial and quasi - biennial components of wind stress fields make west wind anomaly of east pacific and meridional wind stress anomaly converging upon the equator stronger since 1980s ( 5 )风应力距平场具有空间非对称性，同时又有时间非对称性： 80年代以后，太平洋中部的西风异常偏强；从赤道两侧向赤道辐合的经向风应力异常偏强。
In addition to the thermal reasons , the advection of arctic sea ice ( pacific section ) , which is the result of dynamic factors , is closely related to the frequency shift that occurred in chukchi sea 楚科奇海海冰范围的年际变化中存在由低频向高频变化的现象，该现象除了在局地气温变化中存在之外，在北冰洋区域风涡度、波弗特海纬向风、东西伯利亚海经向风等动力因素中也有所体现。
The flow propagates northward and marches across the equation , then passes through the trough of summer monsoon over south china sea and finally gets to the yangtze river valley , which sequentially effect the southwest airflow of the west side of subtropical high ( 3 )在副高西伸过程中，南半球澳大利亚高压北侧的冷空气向北推进，经向风扰动持续向北传播，从而影响副高西侧的偏南气流。
Below 600hpa , the front of east asia was mei - yu front ; mei - yu equatorial front and polar front from the south to the north ; while above 600hpa , there was only mei - yu front . upon these conclusions , we put forward a conception model of east - asia front 在600hpa以下，东亚地区的经向方向锋区从南到北依次表现为梅雨锋，梅雨赤道缝和极锋；而在600hpa以上，只是极锋型的梅雨锋的单一结构。
When south indian ocean in southern hemisphere - zonal ( meridional ) circulation developing in middle latitude and in high latitude of australian , the precipitation in middle and lower reaches of yangtze river rather big ( small ) after some relative process affecting 当南半球南印度洋?澳大利亚中高纬度地区纬向(经向)环流发展时，通过一系列的环流过程影响，长江中下游梅雨期降水偏多(偏少) 。
With the reduction of the leading time , the location of the zonal wind stress area influencing nino3 ssta expands toward the middle pacific from the eastern pacific , as well as the meridional wind stress in the eastern pacific and the western pacific 影响nino3区ssta的纬向风应力区域的位置随风应力超前的时间缩短由东太平洋向中太平洋扩展，经向风应力区域的位置由东太平洋和西太平洋向中太平洋移动。
The latitudinal gradient of coriolis parameter is also an important factor that affects the strength of baroclinic stability , the larger its value is , the smaller strength of the baroclinic stability is . i . e . , the higher the latitude is , the more strength of the baroclinic stability is 科氏参数经向梯度的大小又是影响斜压稳定性强度的一个重要因子，其值越大，斜压稳定性强度越小，即较高纬度的斜压稳定性要强于低纬度。
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。
Moreover , as for average state , the crucial areas of wind stress acting on the two kinds of el nino exist different sites , and the zonal wind stress play a important role on eastern el nino models , the meridional wind stress , however , play a significant effect on the middle el nino models 此外，平均而言，风应力场对两类elnino作用的关键区也有所不同，而且纬向风应力对东部型elnino有重要作用，经向风应力对中部型elnino的产生则起着至关重要的作用。
