A GENERAL EQUATION OF HORIZONTAL MASS DIVERGENCE IN THE ATMOSPHERE

Abstract

A general equation of horizontal mass divergence is derived from the general equation of motion without approximation, except neglect of friction. The sphericity of the earth's surface is included in the derivation. The new equation contains fourteen terms, three of which are already known. It gives a complete picture of the divergence field. The divergence field due to horizontal motion and that due to vertical motion, which have so far been treated separately, are thus linked together.
