The synthetic test of an air pressure wave traveling at 310 m/s passing over a 5° updip slope from a depth of 4 km to a depth of 1 km. a The wave profiles of air pressure (upper row), sea surface (middle row), and bottom pressure (lower row) along x-direction extracted at y = 556 km. The times on the top of the air pressure wave indicate the origin time of the snapshots of the solid or dotted lines. The waves marked with 1, 1′, and 2 are the incident pressure-forced wave, transmitted pressure-forced wave, and the generated ocean gravity wave, respectively. A, B, and C in the left column indicate the locations where we measured the time-series waveforms shown in b. b The waveforms at locations A (left), B (middle), and C (right). The red, green, and blue lines represent the waveforms of the air pressure wave, sea surface height, and bottom pressure, respectively
