gravity wave
2.STUDY OF IONOSPHERIC GRAVITY WAVE DISTURBANCES FROM DRIFT MEASUREMENTS OF A DIGISONDE
3.DISPERSIVE THEORY AND NUMERICAL COMPUTATION OF THE ACOUSTIC-GRAVITY WAVE IN TWO-LAYER MODEL
4.The gravity wave is trapped by Dabie Shan Mountainin the process of propagation and the edge front is formed at the east side of Dabie Shan Moun-tain. The propagation of edge front shows the feature similar to Kelvin wave. The character oflarge amplitude gravity wave in the boundary layer is very obvious.
