Аннотация:We consider a dynamo wave in a solar convective shell for the kinematic -dynamo model. The spectrum and eigenfunctions of the corresponding equations are derived analitically with the aid of WKB-method. Our main aim here is to investigate dynamo wave behaviour in the vicinity of the solar poles. Explicit expressions for the incident and reflected waves are obtained. In particular, we show, that the reflected wave is very weak, in comparison with the incident wave, and it decays propagating equator-wards. In addition, phase shifts and ratio of amplitudes of these two waves are derived.
