So we hoped that using smart algorithms and wind data from around the world, we could maneuver the balloons a bit, getting them to go up and down just a tiny bit in the stratosphere to grab those winds going in those different directions and speeds.
所以我们希望用 巧妙的算法和世界风向数据 来轻微地操纵气球， 让他们可以在平流层 上升或下降一点点 以借助不同速度和方向的风。
