northern and southern hemispheres的意思|示意

WHO has been monitoring epidemiological and virological evidence from all parts of the world, including both Northern and Southern Hemispheres, to determine when the pandemic is over.

世卫组织一直在监测来自世界所有地区(包括南、北半球)的流行病学和病毒学证据，以决定大流行的结束时间。

The moon travels in an elliptical orbit in relation to the equator, swinging back and forth over the northern and southern hemispheres.

月球在与赤道相对的椭圆形轨道上运行，往返于南北半球的上空。

But from both the northern and southern hemispheres, cold air is constantly pouring towards the equator in order to fill the vacuum thus produced.

这样，来自北半球和南半球的冷空气就会不断地涌入赤道附近，补充由于热空气上升造成的真空。

At this time, the sunlight shines vertically on the equator, equally dividing the day and night in both the southern and northern hemispheres.

在这个时候，太阳直射赤道，南北半球昼夜平分。

These preliminary results give us a possible hint to study some global tectonic phenomena, e. g. the asymmetry of the southern and northern hemispheres and the earth's differential rotation.

目前的工作还只是初步的，但为我们探讨全球大地构造上的某些现象，例如南北半球的不对称性和差速旋转问题提供了一种可能的研究思路。

This means the northern and southern hemispheres will sometimes point toward or away from the sun depending on the time of year, varying the amount of light they receive and causing the seasons.

这意味着南半球和北半球会在一年的不同时间段朝向太阳或背向太阳，引起接受的光照量的变化和并产生季节变化。
