A correlation between lower excitation potential and radial velocity of violet-displaced absorption components in the spectra of Wolf-Rayet stars is established. The relationship supports the concept of a radially expanding stratified atmosphere in which the expansion velocity increases outwards. The outermost layers of the atmosphere of one star (HD 151932, WN7) display oscillations with a periodicity of about 3.5 days.
