Abstract
An efficient methodical approach is proposed to the study of pulsation-type motions in the atmospheres of hot stars. Several well-studied stars are used as examples to demonstrate the appropriateness of the method, which allows to study in detail the kinematics of the atmosphere and do asteroseismological forecasts. This approach makes it possible to separately analyze different kinematics of the rising and falling layers of the stellar atmosphere, and to spectroscopically reveal different rotation of the star if such is the case. The differential rotation of atmospheric layers of HD 93521 is confirmed by the model computations.
