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.

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 experimental studies on two wing body junctions and wakes were carried out in a low turbulence level wind tunnel.

"I think we're going to get the upper level winds carrying that ash down for a few more days yet until the upper wind patterns change which will probably not happen until the time frame Thursday-Saturday.

In both instances, the Met Office failed to predict the movements of the jet stream - the high-level wind that races round the world 10km above the surface.

One turbine can produce up to 1, 000 liters of water every day, depending on the level of humidity, temperature and wind speeds, says Janin.

The organisation said decisions on wind projects at local level were being made faster than they were last year, suggesting that developers, communities and local government were "working together better than ever before".
