Nonlinear Effects in Three-minute Oscillations of the Solar Chromosphere. II. Measurement of Nonlinearity Parameters at Different Atmospheric Levels

Chae, Jongchul; Cho, Kyuhyoun; Song, Donguk; Litvinenko, Yuri E. (IOP Publishing LTD, 2018)

Recent theoretical studies suggest that the nonlinearity of three-minute velocity oscillations at each atmospheric level can be quantified by the two independent parameters—the steepening parameter and the velocity amplitude ...
