Rossby Wave Ray Tracing

Description

Rossby wave ray paths are traced from a determined source, specified wavenumber, and direction of propagation. "raytracing" also works with a set of experiments changing these parameters, making possible the identification of Rossby wave sources automatically. The theory used here is based on classical studies, such as Hoskins and Karoly (1981) , Karoly (1983) , Hoskins and Ambrizzi (1993) , and Yang and Hoskins (1996) .
