Ocean noise recorded during a typhoon can be used to monitor the typhoon and investigate the mechanism of the windgenerated noise. An analytical expression for the typhoon-generated noise intensity is derived as a function of wind speed.A “bi-peak” structure was observed in an experiment during which typhoon-generated noise was recorded. Wind speed dependence and frequency dependence were also observed in the frequency range of 100 Hz–1000 Hz. The model/data comparison shows that results of the present model of 500 Hz and 1000 Hz are in reasonable agreement with the experimental data, and the typhoon-generated noise intensity has a dependence on frequency and a power-law dependence on wind speed.
