geographic pole meaning in English

地极
南北极

Complicating this issue is that either magnetic or geographic pole is not static
使这个问题复杂化的是磁极或地极中任何一个位置都不是静止不变的。
The location of the north geographic pole wanders in a small erratic circle - like path called the chandler wobble
北地极的位置以一个被称作张德勒摆动的小的、无规律的、似圆形的路径漂移。
When the twist causes the reversed flux patch to lie closer to the geographic pole than the normal flux patch , the result is a weakening of the dipole , which is most sensitive to changes near its poles
如果扭曲所造成的反向通量斑块，比正常通量的斑块更靠近地理极点，则会使磁偶极减弱，因为磁偶极对于在极点附近的变化最敏感。
For an actual planetwide polarity reversal to occur , such a reversed flux patch would grow and engulf the entire polar region ; at the same time , a similar change in overall regional magnetic polarity would take place near the other geographic pole
如果整个行星的磁极要真的反转，反向通量斑块需扩大到涵盖整个极区；同时，另一个地理极点附近也会发生类似的区域极性全面变化。
