raytracing

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) doi:10.1175/1520-0469(1981)038%3C1179:TSLROA%3E2.0.CO;2, Karoly (1983) doi:10.1016/0377-0265(83)90013-1, Hoskins and Ambrizzi (1993) doi:10.1175/1520-0469(1993)050%3C1661:RWPOAR%3E2.0.CO;2, and Yang and Hoskins (1996) doi:10.1175/1520-0469(1996)053%3C2365:PORWON%3E2.0.CO;2.
