1·During the summer the jet stream (air currents at 7, 000-12, 000m above sea level which affect the winds and weather) changed its course.
夏季，急流(海拔在7,000 - 12,000米的气流，影响风和天气)改变了航向。
2·Observational analysis is conducted of the effects of winter Pacific SSTA on the storm track and jet stream.
利用观测资料分析了冬季太平洋海表温度异常对风暴轴和急流的影响。
3·By using dynamical analysis technique and combining with observational facts of airplane turbulence, a formation mechanism on airplane turbulence in upper jet stream is studied.
作者应用动力学分析方法，结合观测飞机颠簸的事实，对高空急流区飞机颠簸的一种形成机理进行了理论探讨。
4·The main affecting systems include landfall typhoon, low-level jet stream and west trough.
主要影响系统为登陆台风、西风低槽和低空急流。
5·The cold and warm currents meet at the southern side of the shear line and the left side of the low-level jet stream to produce an upward movement of intensive convergence and trigger the rainstorm.
冷暖气流在切变线南侧、低空急流左侧交汇，产生强烈辐合上升运动，触发了强降水。
1·The analysis also tracked weather changes that contributed to massive floods in Pakistan and a heat wave in Russia, saying an "unusually strong jet stream" from June to August was to blame.
该数据还分析了天气变化对巴基斯坦大洪水和俄罗斯热浪的推动作用，认为六月到八月的一场“异常强烈的（对流层顶的）射流”是最终原因。
2·Up near the jet stream above New York, the wind power density can reach 16 kilowatts per square meter.
在纽约上空的射流层（对流层顶）附近，风能密度可达16千瓦每平方米。
