Notes on the Energy Dispersion in the Atmosphere

[摘要] In this paper, the dispersion of atmospheric disturbances has been studied analytically. Particularly, the formation of a new trough over North America following an intense cyclogenesis in the Gulf of Alaska and the blocking action of atmospheric disturbances have been investigated, the former as a boundary value problem and the latter as an initial value problem. In the former problem. the method of Sommerfeld and Brillouin which was used in their study of the propagation of signals in a dispersive medium has been utilised.In the latter problem, using Airy's integral, we have obtained approximate solutions, some of which agree well with those obtained numerically by T. C. Yeh.
