Barotropic Disturbance


1. An atmospheric wave in a two-dimensional nondivergent flow, the driving mechanism for which lies in the variation of vorticity of the basic current and/or in the variation of the vorticity of the earth about the local vertical. When the basic current is uniform, the wave is a Rossby wave . Also called barotropic wave .
2. An atmospheric wave of cyclonic scale in which troughs and ridges are approximately vertical.
