  "Description": "Rossby wave ray paths are traced from a determined source,\nspecified wavenumber, and direction of propagation.\n\"raytracing\" also works with a set of experiments changing\nthese parameters, making possible the identification of Rossby\nwave sources automatically. The theory used here is based on\nclassical studies, such as Hoskins and Karoly (1981)\n<doi:10.1175/1520-0469(1981)038%3C1179:TSLROA%3E2.0.CO;2>,\nKaroly (1983) <doi:10.1016/0377-0265(83)90013-1>, Hoskins and\nAmbrizzi (1993)\n<doi:10.1175/1520-0469(1993)050%3C1661:RWPOAR%3E2.0.CO;2>, and\nYang and Hoskins (1996)\n<doi:10.1175/1520-0469(1996)053%3C2365:PORWON%3E2.0.CO;2>.",
