The absolute velocity was decomposed based on the law of velocity triangle , the absolute tangential velocity , the relative velocity and the relative tangential velocity were presented in this paper 在测得转轮内部的绝对速度矢量后,按速度三角形原理进行分解,得到了绝对速度切向分量、相对速度及相对速度切向分量。
The relationship between the spatial scale dimensions of the initial mesoscale vortex and the variation of typhoon intensity is also discussed . the results show that the interaction can intensify the maximum tangential velocity of typhoon under the condition of certain parameter ranges 结果表明:在一定的合理的参数条件下,中尺度涡旋和台风涡旋的相互作用可以使台风切向风速最大值增加,增加值为4 . 0m / s ,这个结论比m (
Compared with any vibrating systems involving normal impacts , an oblique - impact vibrating system features not only the non - smooth characteristic of impacts , but also complicated dynamics owing to the relative tangential velocity and corresponding friction between two colliding objects 斜碰撞振动系统不但具有正碰撞振动系统力学状态的非光滑特性,还由于相对切向速度和摩擦引起碰撞物体的切向变形,因而具有更大的研究难度。
The most distinct intensification in maximum azimuthally mean tangential velocity occurs when the convective patch is positioned in rmw , the second in the interior region . this intensification exhibit distinct vibration with 6 ~ 7h period and the vibration in inner region diminishes with shorter period Rmw附近扰动使最大平均切向风速增大最明显,其次是内核区,而且这种增强表现出显著的震荡特征,震荡周期约为6 7h ,内核区的震荡较弱,震荡周期略短。
