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。
In the first stage the jet stream lies well to the north and it takes a general west-east direction.
在第一阶段急流远在其北且一般为由西向东的方向。
If a change in the jet stream really is a leading indicator of solar activity, then no new cycle is on the horizon.
如果高速气流的变化真地是太阳活动最重要的指示物，那么新的太阳活动周期还未露端倪。
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。
The immediate cause of the problems is the behaviour of the jet stream, a band of high-level wind that travels east around the world and influences much of the weather below it.
引起这些问题的直接原因是急流[注1]的运动方式 ----在高空、绕地球向东流动并能给下面的天气造成很大影响的一股风。
Studies the jet stream field under different point angles and boundary conditions.
研究了不同圆锥顶角及边壁条件下射流流场。
It is emphasized that the direct feed-back effect of heavy rain on the jet stream is to increase the isallobaric wind.
明确了暴雨对急流反馈的直接效果就是增加其变压风。
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。
The calculated results show that the calculated diagnostic wind fields are more similar to climatology than the geostrophic wind fields, especially, in the jet stream area.
通过对结果的分析，发现用此方法得到的诊断风场比地转风场更接近实际，特别是急流区。
