| THE NON-PERIODIC SEA LEVEL VARIATION IN RELATION TO WIND AND PRESSURE AT THE BOHAI BAY |
|
|
| Abstract: |
| Stochastic process theory is used to make a spectral analysis of the sea level, wind stress and air pressure at the Bohai Bay. It is found that the sea level has two spectrum peak frequencies at 1/120 and 1/67 cph., and the sea level is closely depedent on the force of wind stress in dominant. Coherence function, multiple coherence function, characteristic function of frequency and phase variation are employed to analyze and discuss the relationship between the sea level and wind force. |
