A study of spectral line profile of Hα was conducted on Alpha Orionis based on data taken from Elodie archive data. In this paper we analyse the Hα absorption line profiles and study the correlation between wind component and the changes in pattern of Hα absorption lines of Alpha Orionis. The physical reasons of this phenomenon are discussed.
