查询词典 wind shear

There were the same load characteristics of 1MW, 1.5MW and 2MW blade model, which the tensile stress, shear stress and torque of section were linearly increased with increasing of wind speed; and tensile stress of all test sections of the blade was changed greatly, but shear stress was basically the same in the same wind speed. The shear stress and tensile stress were increased obviously in the place of 388mm to centre of gyration of wind rotor comparing with other section where the phenomenon of stress concentration had for 1.5MW blade model.

对1MW、1.5MW、2MW叶片模型有相同载荷特性，各截面处的拉应力、剪应力、扭矩随风速增大而增大，呈线性增加规律；在相同风速下，叶片各测试截面的拉应力值变化较大，而剪应力值基本相同，但对1.5MW叶片模型，在距风轮回转中心388mm处与其它截面处的剪应力、拉应力比较明显增大，有应力集中现象。

It is forecast that NARI will strengthen at less than climatological rate before crossing the ridge axis due to the combined effect of improving poleward outflow and restricted equatorward outflow, together with generally warm sea surface temperatures and moderate vertical wind shear.

The analyses of the meterological and oceanographical data from seriel observations aboard R/V Xiangyanghong 5 during the voyage of joint AMEX experiment by Australia,China and the United States show that (1) there is high level of humidity within middle and low layers of troposphere at the initial stage of a typhoon's formation,and once a typhoon has fully developed,the highest level of humidity remains within middle layer of tropisphere;(2) although small vertical wind shear is a requisition for a t...

对中、美、澳三国AMEX试验期间&向阳红5号&定点观测到的气象和海洋资料分析得出：①台风形成前，大气整个中、低层空气湿度较大，台风一旦形成，大气湿度最大层主要集中在中空；②风速垂直切变小，对形成台风是一个必要条件，但并非整个对流层风速切变都小，而且不同地区形成的台风，风速切变状况是不同的；③厄尔尼诺年南半球与北半球对应位置同期的θ_G、θ_8、Q_b相差不大，但是南半球的θ_c较北半球的大。
