A computer code that solves the transfer equation in moving atmosphere is prepared for analysis of variability in circumstellar spectral lines. This model gives a theoretical line shape, which consists of a symmetric photospheric line and superposed on it a P-Cyg type component originated in the envelope. Comparison between calculated and observed line profiles will be used to analyze 6 A/mm spectra of F-K supergiants.
