英语翻译The patterns of atmospheric circulation shown in figure

英语翻译
The patterns of atmospheric circulation shown in figure 2.5b suggest that air movement is directly north and south.However,this dose not reflect what we observe from the earth's surface as the earth rotates from west to east.An observer at tropical latitudes observes winds that blow from the northeast in the Northern Hemisphere and from the southeast in the southern Hemisphere(fig.2.6).These are the northeast and southeast trades.Someone studying winds within the temperate belt between 30 and 60 latitude would observe that winds blow mainly from the west.These are the westerlies of temperate latitudes.At high latitudes,our observer would find that the predominant wind direction is from the east.These are the polar easterlies.
\x05 Why don't winds move directly north to south?The prevailing winds do not move in a straight north-south direction because of the Coriolis effect.In the Northern Hemisphere,the Coriolis effect causes an apparent deflection of winds to the right of their direction of travel and to the left in the Southern Hemisphere.We say"apparent" deflection because we see this deflection only if we make our observations from the surface of the earth.To an observer in space,it would appear that winds move in approximately a straight line,while the earth rotates beneath them.However,we need to keep in mind that the perspective from the earth's surface is the ecologically relevant perspective.The biomes that we discuss in the next section are as earthbound as our hypothetical observer.Their distributions across the globe are substantially influenced by global climate,particularly geographic variations in the temperature and precipitation.Geographic variation in temperature and precipitation is very complex.How can we study and represent geographic variation in these climatic variables without being overwhelmed by a mass of numbers?This practical problem is addressed by a visual device called a climate diagram.

大气环流的模式如图2.5 b表明空气的流动是直接南北.然而,这贴没有反映我们所观察的从地球表面如地球从西向东旋转.观察员身份出席热带地区观察之外吹来的风从东北在北半球和南半球的东南部(fig.2.6).这些都是东北、东南的交易.有人在学习风温和30至60纬度带会观察到风吹主要来自西方的.这些都是上西风气流温和的纬度.在高纬度地区,我们的观察者会发现主要风向从东方.这些是极地横过.
为什么不直接风北向南移动吗?不要移动盛行风的一个直接南北走向,因为造成科氏力效应.在北半球,造成科氏力效应,导致一个明显的偏向右边的风的方向,左边旅行在南半球.我们说“明显的”,因为我们看到这个挠度变形,如果我们使我们的观测的地球表面.一个观测者的空间,这样看来,风在近一条直线移动,而地球旋转的堕落.然而,我们必须记住,画面,从地球表面的生态相关观点.预测的,我们在下一章节中讨论作为我们的假设是王宝灿观察者.他们的分布全球下面的全球气候,尤其是地理变异气温和降水量.地理变异在气温和降水量非常复杂.我们怎样才能学习和地理变异,代表这些气候变量没有被大量的数字?这个现实的问题是解决视觉装置称为气候图
