Numerical studies on the approximation of horizontal diffusion using sigma coordinate system

Lee, Jong Wook / Teubner, Michael D. / Nixon, John B. / Cho, Yong-Sik

Abstract In this paper, horizontal diffusion using sigma coordinates was examined numerically. To transform the horizontal diffusion equation, the chain rule was applied twice resulting in extra terms that are cumbersome to treat computationally. Two publisheddirect modifications to the transformed equation were chosen, and numerical solutions using these modified equations are compared to those using the fully transformed equation. Our numerical studies have shown that only the fully transformed equation produces realistic solutions.
