Using 2-layer model which is the special case of the multiple layer model defined by Charney and Phillips, investigation is made, from the view point of numerical weather prediction, on the role of the tilt of trough relative to the vertical for the development of the pressure pattern. At the same time, the mechanism of the transition between the tilted and the non-tilted trough is discussed. Finally, corresponding to the above development, the energetics of westerly wave, i. e., the energy exchange between the potential and the kinetic energy is investigated. Here, the simple expression for the change of these energies is obtained.
