The semi-prognostic method, which introduces a correction term for potential temperature and salinity to the horizontal momentum equation, is applied to an idealized three-dimensional model of buoyancy-driven flow in a single hemisphere. The magnitude of the meridional overturning circulation(MOC) with realistic stratification as well as vertical diffusivity is small, suggesting that the magnitude of the MOC might be overestimated by the previous measurements, and/or that a substantial part of the MOC might be driven by dynamical processes other than vertical diffusion.

半预测方法将潜在温度和盐度引入水平动量方程式引入校正项，应用于单个半球中理想化的浮力驱动流量的三维三维模型。具有逼真的分层以及垂直扩散率的子午倾覆循环（MOC）的大小很小，这表明MOC的大小可能被先前的测量值高估了，并且/或MOC的大量部分可能由MOC驱动。除垂直扩散以外的动态过程。
