That is because the blades, being behind the pole and at an Angle to it, can be given more freedom to yaw about than they would have in an upwind turbine.

那是因为叶片轮处于极轴的后方并以一定的角度倾斜，这样比逆风涡轮机有更大的自由度来偏离原来的位置。

This means that near the north or South Pole you are actually closer to the centre of the earth-where the Angle is being measured from-than you would be at the equator.

这就意味着，如果你身处南极或北极附近，你离地心的距离就比在赤道更近一些——纬度的测量就与地心有关。
