本文研究了小Rossby数情况下大气环流的纬向非对称定常分量。该分量的方程关于平均流线性化。当纬向风和平均流的静稳定度与垂直坐标无关时，得到了纬向风的解析解。该解被用来计算角动量和热量的输运。角动量输运产生Rossby数量级的净收敛，并由纬向平均科里奥利力矩平衡。然而，热传输在这个数量级上消失了。
SummaryThe zonally asymmetric stationary component of the general circulation is studied for small Rossby number without the beta-plane approximation. The equations for this component are linearized about a mean flow. An analytic solution for the meridional wind is found when the zonal wind and static stability of the mean flow are independent of the vertical coordinate. The solution is used to compute the transports of angular momentum and heat. The angular momentum transports give rise to a net convergence of the order of Rossby number and are balanced by the zonal mean Coriolis torque. However, the heat transports vanish at this order of magnitude.
