Eventually this equatorial air mass ceases ti rise and spreads north and south.This high-altitude air is dry,since the moisture it once held fell as tropical rains.As this air mass flows north and south,it cools,which increases its density.Eventually it sinks back to the earth's surface at about 30 latitude and spreads north and south.This air draws moisture from the lands over which it flows and creates deserts in the process.
\x05Air moving from 30 latitude toward the equator completes an atmospheric circulation cell at low latitudes.As figure 2.5b shows,there are three such cells on either side of the equator.Air moving from 30 latitude toward the poles is part of the atmospheric circulation cell at middle latitudes.This warm,moist air flowing from the south rises as it meets cold polar air flowing from the north.As this air mass rises,moisture picked up from desert regions at lower latitudes condenses to from the clouds that produce the abundant precipitation of temperate regions.The air rising over temperate region spreads northward and southward at a high altitude,completing the middle-and high-latitude cells of general atmospheric circulation.

最后,赤道气团停止Ti上升,改向南北扩散.这种高空空气是干燥的,因为降雨量一旦形成,就像热带雨林一样.由于这种气团向南北流动,会变冷,改变了它的密度.最后气团大概在30纬度处扑向地球表面,并向南北扩散.气团带走它所经过陆地上的湿气,并同时形成沙漠化.
空气从30纬度到赤道移动过程中,在低纬度地区形成大气环流圈.如图2.5 b显示,在赤道两边有三个这样的环流圈.空气从30个纬度向两极移动的部分,包括在中纬度地区的大气环流圈之内.当遇上来自北方极冷气流时,这种来自南方的温暖又潮湿的空气会上升.由于它的上升,从沙漠地区挥发出来的降雨量,在低纬区凝结成云,在温带地区产生丰富的降雨.在温带地区上升的空气在高海拔区域向北向南蔓延,完成中高纬度的大气环流.

这个这么长，还要求不用机译，那你也太抠了吧，就5分？
