Before revision: With this approximation, the primitive equations (linearized) become the following: the continuity equation (accounting for the effects of horizontal convergence and divergence and written with geopotential height): the U-momentum equation (zonal wind component): the V-momentum equation (meridional wind component): .Holton, James R., 2004: An Introduction to Dynamic Meteorology.
