从地球赤道平面向北量度的纬度。符号为N,自北纬0°~90°。地球上的纬度的一种,地面上的点在参考椭球体上的纬度,即过该点的参考椭球体的法线同地球赤道平面的交角。它不考虑地球内部物质分布不均和地形的影响,故不同于天文纬度。但地理纬度是由天文纬度订正而得。它同天文纬度的差值不超过30″。
自从一万年前冰河时代结束,气温回升到北纬地区,许多物种都向北迁移。
Since the Ice Age ended ten thousand years ago and warmer temperatures returned to the northern latitudes, many species have migrated north.
在北纬13度、经度230度到250度之间也发现了类似的特点。
A similar feature is found at 13 degrees north between 230 degrees and 250 degrees longitude.
虽然在北纬88°以北其较为罕见,但有证据表明,它们的活动范围甚至一直延伸到北极,向南则延伸到加拿大的詹姆斯湾。
While they are rare north of 88°, there is evidence that they range all the way across the Arctic, and as far south as James Bay in Canada.
