Scaling of motion and governing equations for baroclinic large-scale motions in equatorial ocean

摘要

An obvious characteristic of the baroclinic large-scale motions in the equatorial ocean is that the meridional scale H of motion is far smaller than the zonal scale L. The scaling of motion carefully with this striking characteristic in this paper results in two conclusions, i.e.. the Coriolis terms associat- ed with the horizontal component of the rotation vector cannot be neglected in the governing equations; and the use of the absence of heating is not suitable to the equatorial region. In this paper the equatorial β-plane nondimensional governing equations with the small parameters δ_0 and δ_1 have been obtained.
