Abstract
We investigate the influence of the solar atmospheric temperature stra tification on the amplitude of waves at different heights and its depe ndence on frequency and wave number. Special interest is taken in the influence of atmospheric layers on the appearence of the recently obse rved p-mode crossing features and their location in the Fourier domain . We consider four stratification models. One of them is the standard model with convection-zone, VAL-atmosphere and corona. The others are modifications of this model in order to discuss the influence of speci fic layers of the atmosphere. The changes in the temperature structure significantly influence the velocity amplitude at certain frequency-w ave number combinations at certain heights.
