Some Peculiarities in Excitation and Propagation of the Gravity Waves in Solar Photosphere

摘要

Using the data of observations in the Fe I line, the spatial-time variations of pressure in solar photosphere are reproduced, and local internal gravity waves are identified through the filtration. Based on the power spectra of gravity waves, some integral features of excitation and propagation of g-modes in real solar photosphere are studied which are excited by the dynamical processes near the boundary region of penetrative convection.
