The aim of both teams is to tap into high-altitude wind, which is an energy source that is more abundant and reliable than the ground-level wind on which normal turbines depend.

两个研究小组的目的是一致的：利用更加丰富、稳定的高海拔风能发电，而普通的涡轮发电机则依赖于地表风能。

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.
