Abstract: In this paper， the time-frequency characteristics of ocean ambient noise from 0：00 on May 3 to 0：00 on May 17 2001 were studied used the data obtained from the Asian Seas International Experiment. There was a tropical storm Cimaron occurred during the experiment， thus the approaching and leaving Cimaron caused sea surface wind and wind-generated ocean ambient noise rise and fall obviously. For instance， the ocean ambient noise level at 1 250 Hz showed a period of obvious increasing， stabilization and slowly decreasing. The correlation between ocean ambient noise level and wind speed based on the reanalysis data shows that at high frequency 1 250 Hz the correlation between the ocean ambient noise level and the wind speed is 0.50. At the low frequency 50～400 Hz， the correlation between the ocean ambient noise level and the wind speed is -0.2～0.2. In addition， based on a linear relation between ambient noise level and logarithmic wind speed the regression analysis between ambient noise level and wind speed was performed and fitting coefficient， with inversion error between 5% ～ 20%， established for the inversion of surface wind speed．
