air movement Air movements within the Earth's atmospheric circulation; also called planetary winds. Two main components are recognized: first, the latitudinal meridional component due to the Coriolis force (a deflecting motion or force discussed by G.G. de Coriolis in 1835. The rotation of the Earth causes a body moving across its surface to be deflected to the right in the N hemisphere and to the left in the S hemisphere); and secondly, the longitudinal component and the vertical movement, resulting largely from varying pressure distributions due to differential heating and cooling of the Earth's surface (地球大气循环中的空气流动，也叫行星风。主要由两个力分量引起：第一，纬度子午线上的力分量即地球自转偏向力(由G.G. de Coriolis在1835年提出的一种偏向运动或偏向力：地球的自传导致横越其表面的物体移动在北半球的时候向右偏转，在南半球向左偏转)；第二，经度纵向分量和垂直运动，主要由地球表面温度差分加热和冷却造成的不同压力分布所引起。) |
