Jet streams are a symptom of the overall atmospheric movement, not a driving force.
急流是整个大气运动的征兆，而不是驱动力。
At high altitude you have jet streams, and the wind velocity is not the same at all altitudes.
在高海拔处会有高速气流，风速在不同的海拔处，并不相同。
All this affects the movement of the jet streams, which reflect but do not create air movement.
所有这些都会影响急流的运动，急流的运动只是反映了而不是创造了空气的流动。
That indicates that there will be little or delayed activity in that cycle, said Hill, who tracks jet streams.
这预示着这次的周期太阳活动要么不剧烈，要么会延迟。
These experts are especially concerned that new patterns of air movement in the Arctic could disrupt the Northern Hemisphere's jet streams - which are apparently weakening and moving northward.
这些专家尤其关注北极的空气流动的新模式可能会扰乱北半球的急流——很明显的是，这种气流正在削弱并向北方移动。
The supergeostrophic behavior of low level jet streams is caused by the nonequilibrium relating to the jet strengthening or weakening instead of the quasi-equilibrium of the saturated moist air.
暴雨地区急流的超地转现象并不是饱和湿空气的难平衡现象，而是与急流加强减弱有关的不平衡现象；
The impinging jet injection device improves combustion efficiency. If the fuel streams impinge with the airstreams directly at the exit of air-inlet, it makes negative effect on combustion efficiency.
燃气射流与空气流在进气道出口直接撞击不利于燃烧效率的提高。
