在旋风波和长波的尺度上，热量和动量的运动传递是从它们的力学知识中推导出来的。熵的水平传递规律与混合的概念无关，但与非各向同性扩散的规律相似。这一规律准确地反映了北半球热通量的年变化。微扰理论揭示了传递的现实空间变化，并为计算传递系数提供了合理的基础，从而可用于计算其他保守量的通量。最重要的是，位涡的赤道方向通量被很好地定义，并被证明可以决定动量uv的水平通量。然后确定平均地面风和平均经向环流（被认为是摩擦驱动的）。一般环流模式是由这些特性定义的，并对一个简化情况进行了综合分析，并与在墨西哥湾流、中间层、碟盘实验以及对流层中观测到的运动进行了比较。
The transfer of heat and momentum by motion on the scale of cyclone waves and long waves is deduced from a knowledge of their mechanics. The law of horizontal transfer of entropy is independent of notions of mixing but is similar to that for non‐isotropic diffusion. The law accurately represents the annual variation of heat‐flux in the Northern Hemisphere. Perturbation theory suggests realistic spatial variations for the transfer and provides a rational basis for calculating transfer coefficients which can then be used to find the flux of other conservative quantities. Most importantly the Equatorward flux of potential vorticity is well defined and is shown to determine the horizontal flux of momentum uv. The mean surface winds, and the mean meridional circulation (which is seen to be frictionally driven) are then determined. A model of the general circulation is defined by these properties, and this is integrated analytically for a simplified case and compared with motion observed in the Gulf Stream, the mesosphere, and dishpan experiments as well as the troposphere.
